Description

Synthetic detergent and preparation method thereof

The invention relates to a super concentrated, high-density solid synthetic detergent, in particular to a laundry solid synthetic detergent which rapidly disintegrates in normal temperature or low temperature water and a preparation method thereof, which are suitable not only for hand washing, traditional washing machine washing fabric, but also It is suitable for the washing of so-called environmentally friendly washing machines without washing powder. Background technique

There are two main types of products in the global detergent industry: First, fertilizer (fragrance) soap. It accounts for approximately 14% of the global market for detergents. Second, synthetic detergents. It accounts for approximately 86% of the global market for detergents. In synthetic detergents, detergents account for about 2/3, and liquid detergents account for about 1/3. Solid synthetic detergents are extremely rare.

In the field of textile washing, soaps, granules or powdered laundry detergents, clear liquids or slurried liquid detergents are most common. Among them, soap is a sodium salt or a potassium salt of various fatty acids, and is generally formed by saponification of fats and oils, by a full boiling method, a semi-boiling method, a cooling method, a carbonate method, or the like. For example, according to the full boiling method, the oil and alkali are placed in a saponification kettle, heated and boiled, and then saponified, transferred to a salting-out tank, salted with concentrated brine, and processed into a solid soap product by the upper soap; As a by-product. In terms of raw materials, soap can be selected from tallow, sheep fat, bone fat, coconut oil, leather oil, linseed oil, cotton oil, peanut oil, wild vegetable oil, etc. In practice, soap is consumed by a large amount of caustic soda (caustic soda), salt, soda ash. , caustic potash, sodium citrate, sodium bicarbonate, disodium phosphate, and the like. For example, in the whole boiling method of soap making, it is necessary to add 30-40 kg of caustic soda per 100 kg of net oil.

Soap has many drawbacks. First, it consumes a lot of oil. Each production of a piece of soap consumes about three or two natural oils. The use of petroleum products to synthesize fatty acids can replace animal and vegetable oils, but the soap has poor decontamination ability and the textiles tend to be sticky after washing. Second, the washing effect is poor and there may be significant dirt remaining. When the soap encounters minerals in hard water, it will chemically react to produce powdery scum, which is easy to adhere to the clothes and affects the cleaning effect. Especially when washing light or monochrome clothes, the residual dirt may be more obvious. For example, when washing textiles with hard water, soap and calcium ions in the water, magnesium ions to form calcium soap, magnesium soap, not only waste soap, but also make the textile color yellow, fabric knot. Third, the versatility is poor. Soap making requires the use of large amounts of caustic soda, which makes the soap alkaline and corrosive, not suitable for washing silk, wool fabrics, and certain chemical fiber fabrics. Fourth, quality is difficult to guarantee. For example, in soap If the hard oil is too much and the freezing point is high, the product is prone to cracking and squashing, and the washing performance is seriously degraded. Fifth, there is a pungent smell. The soap itself often has a pungent smell. This odor will remain on the textile without repeated rinsing and long-term exposure. Sixth, irritating the skin. The sodium hydroxide content of the soap is usually high, which makes the soap alkaline and corrosive. On the contrary, human skin is generally a weak acid environment. When hand washing, soap irritates and damages the skin, and soap-washed underwear also irritates the skin, causing discomfort and fever. Seventh, it is not easy to measure usage. Soaps are generally not used by automatic disintegration, dissolution, and are often applied to the surface of the textile by mechanical friction. How much soap is used in a single piece of textile, which has no measurable measurement standards. When too much soap is used, the textile fibers are easily damaged and the odor is more residual. If too little soap is used, the textiles are not easily washed. Due to the above drawbacks of soap, synthetic detergents have gradually become the main products in the field of textile washing in recent years.

The detergency of a synthetic detergent is related to the molecular structure of the actives it contains. The active material is derived from various surfactants, and its basic molecular structure is that one end is composed of a longer hydrocarbon chain to form a hydrophobic group or a lipophilic group, which is insoluble in water and soluble in oil; the other end is composed of a shorter pole. A group such as a carboxylic acid group -COOH or a sulfonic acid group -S03H constitutes a hydrophilic group or an oleophobic group, is soluble in oil, and is insoluble in water. When the surfactant is added to the water, the lipophilic portion of the molecule repels the water and extends to the air, and the hydrophilic portion is attracted by the water molecules to cause adsorption, and a dense layer of lipophilic groups is formed on the surface of the solution. In this way, the surface of the aqueous solution forms a hydrocarbon chain interface, which greatly reduces the surface tension of the solution and enhances the wetting, penetrating, emulsifying and decontaminating ability of the solution. Synthetic detergents mainly include washing powder and liquid lotion.

The washing powder is mainly made up of a large amount of inorganic auxiliaries such as pentasodium, sodium silicate, sodium carbonate, sodium sulfate, etc. by linear sodium decylbenzenesulfonate and sodium alkylbenzene sulfonate, and is made into a fluffy and dry powder by spraying. Then, it is mixed and added with a washing aid or the like for bagging. At present, some new washing powder products have appeared on the market, such as adding a small amount of nonionic surfactants and enzymes to the washing powder to improve the washing effect. However, washing powder generally contains a large amount of sodium tripolyphosphate. Sodium tripolyphosphate is an important detergent component. Its main functions are: softening water, preventing metal ions from damaging surfactants; dispersing, emulsifying, and peptizing stains; avoiding re-precipitation of stains and maintaining the vivid color of the washed objects; Provide a certain amount of alkalinity, maintain the washing liquid at a suitable pH value, reduce the irritation to the skin; absorb moisture to prevent the washing powder from agglomerating, and keep dry and granular. However, the discharge of phosphorus-containing washing powder waste into the environment is likely to lead to severe eutrophication, which causes the water ecosystem to be broken, resulting in deterioration of water quality. For example, about 4 million to 700,000 tons of sodium tripolyphosphate is used in China's annual production of 4 million tons of detergent. These phosphates are eventually discharged into the river with wastewater. The rivers and lakes make the water eutrophication, causing the algae in the water to rapidly and massively multiply, eventually producing red tides in the offshore waters, causing economic losses of about 10 billion people per year.

At present, there are non-phosphorus washing powders on the market at home and abroad. It mainly uses 4A zeolite instead of sodium tripolyphosphate as a builder. 4A zeolite can adsorb calcium ions in water well, but its adsorption to magnesium ions is poor, so its cleaning performance is limited. Further, the 4A zeolite is insoluble in water, and the detergent synthesized with 4A zeolite tends to adhere to the laundry when washing the laundry, which is disadvantageous for rinsing. Developed countries such as Europe and the United States generally use layered sodium silicate as a builder to synthesize detergent. The layer of sodium silicate has excellent hard water softening performance, strong degreasing ability, strong synergistic ability with surfactant, good permeability to soil, dispersibility, emulsifying property, sterilization, rust prevention and corrosion resistance. The industrial detergents have the least environmental pollution and are currently the most suitable detergent builders to replace phosphorus-containing builders. The layer of sodium silicate has good adsorption properties for Ca and Mg ions in water, especially the adsorption of Mg ions far exceeds that of 4A zeolite, so its washing effect is obviously better than that of 4A zeolite, and layer silicic acid is used. The dissolution performance of sodium detergent as a builder is better than that of 4A zeolite, which is good for rinsing and reduces secondary pollution to clothing. However, in the mild washing environment of weak acid and weak alkali, especially in the mild washing environment of normal temperature and low temperature water, the washing performance of the layer sodium silicate is weak.

With the popularization of high-grade fabrics, especially wool, cashmere, silk, hemp, blended, and advanced chemical fiber fabrics, washing and care of textiles in a mild acid, weak base, neutral mild washing environment has become a new technical requirement. . It is particularly noteworthy that Chinese people's washing habits are different from those in the West. Chinese people like to wash textiles in normal temperature and low temperature water. In general, when the water temperature rises, the surface tension of the washing water is lowered, and the required detergent is reduced. When the water temperature is lowered, the surface tension of the washing water is increased, and the required detergent is increased. It is always one of the important research directions of Chinese technicians to find efficient synthetic detergent components and compatibility methods for the mild washing environment of normal temperature and low temperature water.

In addition to the above technical development needs, there are other deficiencies in washing powder:

First, it is highly degreasing and easily damages clothing fibers and skin. For example, a person's hand touches the washing powder with a burning sensation, which can cause rough and dry skin.

Second, waste water and electricity. The types of surfactants used in different washing powders are different, and some surfactants still have good foaming ability in a very small amount and are not easy to wash. Washing powder produces a lot of foam, and it takes a lot of water to rinse the laundry, which is much more wasteful than soap.

Third, it is easy to have residue and easily damage clothing. The amount of washing powder is too much. The excess washing powder can not only increase the detergency, but it is easy to remain on the clothes, which is not easy to clean. It also irritates the skin. For example, washing powder contains bleaching effect. Excessive use will cause the clothes to fade and damage.

Fourth, the washing concentration is not easy to control, and the washing effect is poor. The washing concentration depends on the amount of washing powder, the volume of washing water, etc., and it is very difficult to control. Under normal circumstances, the amount of washing powder will be too large, which is easy to cause waste, and improperly increase the amount of washing powder, which will reduce the detergency. For example, when the detergent reaches a certain concentration and the surface activity of the aqueous solution reaches a maximum value, the detergency will no longer increase as the amount of detergent added increases, but will decrease. Scientific experiments have shown that the optimal washing concentration of washing powder is generally

0.1%-0.3%, this solution has the highest surface activity and better decontamination effect. When the concentration exceeds 0.3%, the detergency of washing decreases. Excessive washing powder will not increase the decontamination effect, and it will damage the clothes fiber due to the increase of alkalinity in the solution.

Fifth, the density is small, and the size of the plastic loading tool is very large. After being damp or squeezed, the washing powder tends to agglomerate and affect the washing effect. Washing powder is generally fluffy and has a density of only about 0.28-0.45 g/ml. Therefore, the plastic loading device is relatively bulky, generally a soft plastic bag. The plastic bag is generally no longer sealed after opening, so that the washing powder is easily agglomerated by moisture. In addition, the laundry powder is a hollow granule which is easily squeezed in a soft plastic bag to be broken and agglomerated. The agglomerated washing powder does not easily dissolve, thereby damaging the washing effect.

Sixth, washing powder is not easy to measure. The volume and density of the washing powder are not easily controlled, which is mainly caused by the preparation process. Factors such as detergent slurry concentration, slurry pressure, spray gun diameter, inlet air volume, airlift volume, and post-mixing may affect the volume and density of the washing powder, making it difficult to measure the amount of washing powder required for a single piece of clothing. Moreover, due to the different specific gravity of the particles, the distribution of enzymes, bleaches, zeolites, etc. in the loose detergent particles is not uniform. Even if the user accurately measures the amount of detergent powder to be dispensed in a single washing task, the content of each component, such as detergent, detergent builder, etc., tends to deviate from the actual required value. Therefore, how to package each washing component corresponding to a specific washing task in a single detergent monomer is a very urgent requirement of the user.

Seventh, after the opening, the washing powder is easily deteriorated. In a cool, dry environment, sealed detergent can be stored for six months to nine months. After unsealing, the moisture in the air will agglomerate the washing powder and degrade the function of some components, such as enzymes and bleaches, especially the enzymes. The free acid in the washing powder will destroy the protein structure of the enzyme, making it The function is greatly reduced. Generally, after six months of storage, the washing function will decline by 15% -60%. In some cases, such as washing powder stored at high temperatures, the enzyme will completely lose its activity. In addition, the essence will quickly evaporate after the washing powder is opened, and may be completely volatilized after changes in conditions such as time and temperature. Eighth, the versatility of washing powder is poor. Washing powder is suitable for washing cotton, linen, chemical fiber and its blended fabric. However, washing powder is generally alkaline, which denatures proteins and causes damage to hair, silk, and the like. Therefore, most washing powders are not suitable for washing wool, silk fabrics or their blended fabrics. Its versatility is poor.

Ninth, the time during which the components of the washing powder function is not easily regulated. The dirt on the clothes mainly contains solid dirt, oily dirt, liquid dirt, etc., and the manner and order in which the various soils are removed during the washing process are different. For example, solid soluble soils are mostly soluble in water and can be quickly removed by soaking and mechanical rubbing. Insoluble soils are generally removed by detergents, and some require the use of solvents, oxidizing bleaches, reducing bleaches, and the like. During the washing process, the manner in which the surfactant exerts the functions of wetting, emulsifying, dispersing, solubilizing, foaming, defoaming, and sterilizing is not completely the same. The granulation mixing and coating relationship between the components is appropriately set in accordance with the fiber characteristics and the decontamination principle, thereby setting the manner and order of dissolution and release of the washing components, which is very advantageous for improving the washing effect. However, after the washing water is dissolved, the components of the washing powder are almost in contact with the washing water or the laundry at the same time, and the above setting cannot be provided. In summary, the physical structure and preparation process of the washing powder does not allow people to make the above settings.

In addition to washing powder, another important synthetic detergent is a liquid lotion. Liquid lotion is a combination of a variety of surfactants and 40-80% water. Since the surfactant has good water solubility, the biggest feature of the liquid lotion is that it has excellent water solubility and has excellent washing characteristics at low temperatures. In addition, liquid lotions are less irritating to human skin and have no alkali burning sensation. However, liquid lotions also have some disadvantages.

First, liquid detergents are greatly affected by the solubility limit and the compatibility of surfactants. Therefore, in the liquid lotion, some good additives cannot be added or only added in a small amount, which greatly reduces the washing effect of the liquid lotion. For example, up to 40-60% of inorganic builders can be added to the detergent formula. The amount of inorganic builder added to the liquid lotion is typically 3-10%.

Second, the liquid lotion has a strong foaming ability, which leads to rich foam, which makes the laundry difficult to rinse, and wastes a lot of water and electric energy.

Third, 40-80% of water is generally added to the liquid lotion, whereas the amount of the detergent component is not large, which makes the liquid lotion product consume a large amount of water and transportation costs. In addition, liquid detergents are generally delivered in plastic bottles and drums, and as with detergents, they also produce large amounts of plastic waste.

In addition to the above-mentioned laundry products such as the above-mentioned soaps, washing powders, and liquid lotions, a small solid detergent is described in the patent documents such as GB911204, US3953350, JP60-015500A, and EP711827A. However, these detergents are basically small soaps, Small pressed washing powder blocks, etc. Compared with the present invention, the volume is very large, the weight of the monomer is generally more than 100 grams, the density is slightly higher than the washing powder, the minimum is not less than 50 grams, the effective content is low, the washing effect is poor, and the market prospect of the market is lacking. Similar small solid detergents are also disclosed in other documents. For example, Xu Baocai, Zhou Yawen, Wang Hongzhong's "Detergent Formulation Process Manual", Chemical Industry Press, January 2006, first edition, page 239, discloses a small solid wash weighing about 30 grams and a diameter of about 2 mm. Agent. Liao Wensheng's "Detergent Materials and Formulations", Chemical Industry Press, March 2006, first edition, pages 102-103 also discloses some solid detergents with a monomer weight of up to tens of grams, but basically It belongs to the pressed washing powder block or soap bar, and it is bulky and lacks the application prospect of the market. Due to the lack of technology and market development expectations for small solid detergents in the scientific and commercial world, other scientific literature has not paid attention to it. For example, none of the following documents mention such detergents. Tang Yumin, ed., Synthetic Detergent and Its Application, China Textile Press, 2006. The first edition of the month. Ma Zhengsheng, "Phosphorus-Free Washing Auxiliaries", Chemical Industry Press, March 2005, first edition. Editor-in-Chief Li Dongguang, Handbook of Detergent Materials, Chemical Industry Press, Second Edition, January 2006. Hua Zhangxi, Xu Qing, "Detergent Enzyme Application Manual", China Light Industry Press, first edition, July 1999. Bai Jinquan, Bao Yuquan, “Application of Surfactants in the Washing Industry”, The First Edition of the July 2003 issue of the Chemical and Applied Chemistry Publishing Center.

However, the principle and application formula of surfactants edited by Zhong Pinghai, Jiangxi Science and Technology Press, May 2005, the first edition of 33 pages pointed out that the main development trend of detergents is super concentrated, high density, low temperature and low foam, It is environmentally and human safe and has various functions. Despite this, the book does not disclose solid detergents that meet this trend. The invention can overcome the shortcomings and defects of mainstream washing products such as soap, washing powder and liquid lotion, and utilizes unique formula and process to manufacture ultra-concentrated, high-density, low-temperature and low-bubble, environmental and human body safety and various functions. Gentle wash products.

In addition, electrolysis and electromagnetic washing machine technology without the use of chemical detergents have appeared in large numbers. For example, CN03143941.1 relates to a washing machine washing method without detergent. It can temper or activate the washing water, then carry out electrolysis, control the mechanical strength or time of washing, and the pH of the electrolyzed water, so that washing without chemical detergent can be achieved. The document CN03143942.X relates to a washing machine. It uses a washing method that does not use detergent. The claimed washing method of the patent is to electrolyze the wash water to a pH between 9.5-10.6. Using alkaline water produced by electrolysis, the washing machine can be washed efficiently and dispensed with rinsing. The washing machine can sterilize, disinfect, care, etc. the fabric by using the acidic water produced by electrolysis. A so-called tap water modifier without detergent The environmentally friendly washing machine enhances the washing effect. The components of the tap water modifier and their uses are disclosed, for example, in the patent application CN200310113629.9, the patent ZL03143941.1, and other non-patent documents.

A washing machine without detergent is not only a direction of patent deployment, but also a commercial development direction of the washing industry. In the business world, Sanyo Corporation of Japan first introduced an electrolyzed water washing machine without washing powder. In 2004, Haier also introduced an electrolyzed water washing machine that does not use washing powder. At present, Haier's turbine and drum washing machines have new models that do not use washing powder. The current so-called washing machine without washing powder can mainly achieve decontamination and sterilization functions. However, the washing process is not only decontamination and sterilization. The role of detergent builders such as proteases, flavors, and bleaching agents in synthetic detergents is irreplaceable. Adding a specific detergent or builder to this washing machine allows for better washing results. The present invention relates not only to hand washing, solid detergents used in washing clothes for conventional washing machines, and preparation processes thereof, but also to related art inventions of so-called environmentally friendly washing machines which do not use washing powder. Summary of the invention

(1) Technical problems to be solved

SUMMARY OF THE INVENTION The object of the present invention is to provide a solid synthetic detergent for the above-mentioned deficiencies.

The invention also provides a method for preparing a solid synthetic detergent.

In the present invention, "clothing", "fabric", "textile" and the like generally refer to various products which can be washed by hand washing and washing machine, and "solid detergent" refers to an independent solid monomer capable of maintaining its physical shape and structure. It can be a homogeneous or multi-phase monomer. The technical solution of the present invention is to select a specific component, preferably a high effective substance content multifunctional component, according to a preset active release mode and time, to perform targeted compounding and pass the component. The original mixing, granulating, tableting and other preparation processes produce ultra-concentrated, high-density ultra-small solid micro-detergents, which enable all the washing components of mild, fully biodegradable washing of single-piece washing objects in low-temperature washing water. Such as high-efficiency washing components, mild washing components, main washing and dissolving inorganic washing, washing and washing components, functional washing components, disintegration and dissolution-assisted sterilization components are accurate, stable, efficient, safe and meticulous. Intelligently sealed in a solid detergent monomer. Moreover, the selection, compatibility, mixing, granulation, and tableting process of the components actually "memorize" the functional relationship information such as disintegration, compounding, and washing between the washing components, and the manner in which the performance of each washing component is exerted. With time information. These are preset by people The information is actually the "instructions" that people set up for solid detergents by physical and chemical methods, which are also stored and packaged in a solid detergent monomer. The above-mentioned sealed substances are successively released from the application of the monomer to the washing water, and the stored or encapsulated information or instructions are dissolved, disintegrated, wetted, solubilized, foamed, defoamed, emulsified, and demulsified. The washing process of dispersing, agglomerating, flocculation, separation, disinfection, sterilization, care, conditioning, bleaching, etc. is released and executed. In this way, the washing process becomes an informational instruction execution process that is pre-controlled by artificial intelligence. Among them, artificial intelligence has set up almost all physical and chemical processes, and the user only needs a simple placing action and a command to start washing, so that the process can be actually reproduced. Accordingly, the present invention is actually directed to a refined solid synthetic detergent for presetting and storing a washing manual instruction information system, and a refinement processing method for storing and packaging the information system. The present invention enables a one-time precise delivery of the detergent to be free of any auxiliary measuring instrument or gauge.

In the solid synthetic detergent of the present invention, the components are "precisely, stably, efficiently, safely, carefully, and intelligently encapsulated in a solid detergent monomer". "Precision" means that the components required to wash one or more pieces of clothing are properly dosed; "stable" means that the components required to wash one or more pieces of clothing are physically and chemically Sealed in solid monomer, does not volatilize, inactivate, combine, hydrate, escape, deposit, move, etc., its physical and chemical state remains basically unchanged; "efficient" means that the efficiency and effect of sealing is very good, in soap In other types of lotions such as detergents, liquid detergents, etc., such sequestration is unlikely to occur and is not effective; "safety" refers to conventional pressure shock, shock, flipping, squeezing, exposure, moisture, unsealing, Beating or the like does not change or destroy the state of the above-mentioned storage; "fine" refers to the specific fiber, weight, volume of clothing, each component is finely compatible and sealed, compatibility and storage process presets for future washing needs Almost all physical and chemical processes, which are not possible in other lotions; "intelligence" refers to the selection, compatibility, mixing, granulation, tableting process of components Recalling the functional relationship information such as disintegration, compounding and washing between the washing components, as well as the performance and time information of the performance of each washing component, so "storing" is used to set and reproduce the physical and chemical processes. Intelligent storage. It can be said that the solid synthetic detergent of the present invention is actually an intelligent lotion.

The technological innovations and the technical biases they overcome are:

First, according to the conventional technology prejudice, the pressed monomer detergent is to press a conventional detergent such as washing powder and soap into a more compact washing block. The solid detergent of the invention does not use washing powder or soap, but independently selects detergents, detergent auxiliaries, etc., prepares unique granules through a unique granulation process, and finally suppresses one or more granules, or presses The mixture of granules and powder produces a unique solid detergent.

Second, according to conventional techniques, the dissolution and disintegration of solid detergents is equivalent to a simple acid-base neutralization reaction, and the acid-base ratio should be chemically balanced. The dissolution and disintegration process of the present invention is suitable for increasing the capillary content, and by using a swelling type, an effervescent type, a high solubility substance, and the like, and a mixing method thereof to achieve dissolution and disintegration of the detergent. Moreover, in the foaming type disintegration, the chemical ratio of the acid-base substance is preferably unbalanced, for example, the amount of acid exceeds the acid amount of the acid-base reaction by more than one time. Due to this imbalance, the contact speed and probability of acid-base components between different particles are greatly improved, thereby greatly increasing the disintegration speed. Among them, the excess acid or base preferably has a washing and washing function.

Third, according to conventional technology bias, low foaming detergents have poor detergency. The detergent of the present invention can achieve less foaming and enhance detergency by a new component and a compatibility method which are preferably low in foaming power but strong in detergency. Poor foaming power, which can greatly reduce the number of rinses and water consumption. For silk, cashmere, etc., the user can finish the washing process without rinsing, and the water saving effect is better.

Fourth, according to traditional technology bias, anionic and cationic surfactants are not compatible. For example, Mr. Ping Pinghai's "Surfactant Principles and Application Formulas", Jiangxi Science and Technology Press

The first edition of May 2005, page 3, states that cationic surfactants cannot be used directly in combination with anionic surfactants. In traditional lotions, especially liquid lotions, anionic and cationic surfactants are generally not suitable for direct compatibility. However, in the present invention, the anionic and cationic surfactants can be directly used together, and after the disintegration of the detergent, the anionic surfactant is rapidly immersed in the fiber to exert the desired effect, and the cationic surfactant can be controlled and sustained release, and is substantially unaffected. In the case of anionic surfactant interference, it functions independently of insecticide and antistatic.

- Fifth, according to the traditional technology bias, the release method and time of the washing component cannot be preset after the detergent is dispensed at one time. The invention sets different component combinations in the steps of mixing, spraying, granulating, etc., and can effectively control the release mode and time of the washing component. For example, after the mixture of the anionic surfactant and the detergent builder is granulated, the secondary granulation of the fast-disintegrating component is sprayed, which can rapidly release the above-mentioned washing component. On the contrary, the cationic surfactant can be slowly collapsed. Spraying, so that the relevant components are released slowly.

Sixth, according to the conventional technical prejudice, detergents of less than 5 grams, especially less than 3 grams, and even less than 1.5 grams, cannot be washed in an adult dress. The prior patents and non-patent documents do not disclose a single solid detergent which washes 5 grams of a single adult dress, especially 3 grams, or even less than 1.5 grams. The ultra-concentrated, high-density solid detergent is designed in the present invention with a high effective content component and a reasonable ratio. After repeated calculations, in this detergent, The most effective amount of a surfactant may not be less than 50%. From the viewpoint of the amount of use of the solid detergent, the present invention achieves the first micro-washing, that is, washing using a trace synthetic detergent.

Seventh, according to the conventional technology bias, when a solid detergent is dispensed at one time, the user cannot achieve a controllable ratio of the components in the detergent. When a solid detergent such as laundry detergent is applied at a time, the distribution of enzymes, bleach, zeolite, etc. having different specific gravities between the hollow particles of the washing powder is uneven, which causes the components in the detergent to fail to achieve a controllable ratio. This situation has been changed with the advent of the present invention. Since the components having different specific gravities are encapsulated in the particles or monomers of the solid monomers, the above ratios have been completely controllable.

Eighth, according to the conventional technical bias, without relying on any auxiliary measuring instruments or gauges, the volume, weight and density parameters of the user's single-discharge detergent cannot simultaneously correspond to the fiber content, volume or weight of a single washing object. In the field of washing powder, liquid lotion, etc., unless the auxiliary measuring instrument or measuring tool is used, the volume, weight and density parameters of the user's single-discharge detergent do not correspond to the fiber content, volume or weight of a single washing object at the same time. The invention enables a garment to be delivered corresponding to a solid detergent. This allows people to get rid of any auxiliary measuring instruments or gauges for targeted and precise delivery.

Ninth, according to the conventional technology prejudice, the solid detergent itself cannot seal the components such as enzymes and flavors, thereby preventing the deterioration of the detergent quality. After the solid detergent such as washing powder is unpacked, the enzyme activity is generally attenuated by about 50% before the washing powder is used up, and the essence is basically evaporated. In the granulation and granulation process, the enzyme, the essence and the like are sealed in the granule or the body to prevent the moisture from reacting, deteriorating, attenuating or escaping. Especially in solid detergents with protective coatings, the relevant components are sealed and protected more well.

Tenth, according to the conventional technology prejudice, the solid detergent should be mixed with a small amount of binder, form a paste and then press-formed, and there is a technical prejudice that the solid detergent should be prepared by a soap making process. The invention uses a biomedical technology combined with a detergent compounding technology to open up a new process for producing a solid detergent. The invention needs to carry out reprocessing on raw materials, and explores the best technical route of one spray, four mixing and three granulation. In particular, the present invention utilizes a boiling spray process in the manufacture of liquid solid detergents to enable the use of high performance liquid surfactants in the preparation of solid detergents. According to the present invention, the components are mixed four times and three times according to the disintegration mode and time design, the active ingredient release mode and the time setting, and finally the particles are mixed at a high speed to press the solid detergent of the present invention at a high speed. This combination and granulation method is an innovation of the present invention, and the obtained granules and detergent body are also innovations of the present invention. The technical difficulties overcome by the present invention mainly include: controlling the dissolution rate of the solid detergent in combination with the temperature conditions and the requirements of the washing process; combining the manner and time of releasing the components, preparing the granulation and solid detergent; The type and degree of washing objects and scale, the reasonable design of components, proportions, and processes; the integration of solid washing and fabric conditioning properties; the solid detergent to achieve a hand-washing effect that does not hurt the hand; injecting natural bio-extracted protein Solid detergents, a new technical point of view for replenishing and remedying fabric fiber damage; selecting disintegrants and disintegrating methods according to requirements, especially achieving rapid disintegration of high-density detergents, rapid disintegration in specific areas, and specific groups Rapid or sustained release disintegration of the fraction.

(2) Technical plan

The invention first relates to an ultra-concentrated, high-density solid synthetic detergent granulated and compressed by a high effective content surfactant, wherein one or more water-soluble surfactants act as a disintegration group on the periphery of the particles. And the volume, weight and density parameters of the individual detergents simultaneously correspond to the fiber content, volume or weight of the individual washing objects, preferably one detergent washes one piece of fabric, and the active ingredient content of one of the most used surfactants is not low. At 50%. Through trial and error and calculations, the present invention teaches that an ultra-small portable solid synthetic detergent monomer having less than 5 grams and less than 1 cubic centimeter requires at least one surfactant having an effective content of not less than 50%. According to the components, compatibility and process of the present invention, less than 5 grams of ultra-concentrated, high-density solid synthetic detergent monomer can be disintegrated in two seconds to nine minutes after the washing water is introduced, preferably five seconds to one minute. Disintegration is completed within. However, some of the detergent builders are coated with the disintegrated particles and can take longer to release. The combination of lauroyl sarcosine sodium and sodium dodecyl sulfate is the first time the detergent is used in the present invention. Tests have shown that the sum of the weights of the two components can achieve a good washing effect between 5% and 80% of the total weight of the detergent, preferably between 40% and 70%, and the detergent performance is more prominent. It is estimated that the components and compatibility requirements applicable to the present invention, and the components of the granulation and tableting process of the present invention may be powders or granules, and the average particle diameter of the powder is between ΙΟηιη-ΙΟμιη, and the average particle size of the particles is Between ΙΟμηι- Ι ΐΏΐΏ. Through trial and error, the present invention indicates that the single solid washing detergent corresponding to the small underwear to the down jacket can be between 0.3 g and 5 g, and the density is between lg/ml and 20 g/ml. For normal laundry, the weight is between 0.8 and 1.5 grams and the density is between 1.07 g/ml and 6 g/ml.

In the component selection, the washing powder is generally selected from a large amount of alkali inorganic salts and anionic surfactants, and a small amount of nonionic components. Liquid lotions are generally anionic, with a small amount of nonionic and trace inorganic salts, and a large amount of water components. In contrast, the present invention is A wide range of surfactants, such as anionic, nonionic, cationic, zwitterionic, can also be achieved by the choice of one or more surfactants. The present invention creatively achieves direct compatibility of anionic and cationic surfactants compared to current general laundry detergents and liquid lotions. In the effective substance content, the anionic, nonionic surfactant active content of the washing powder is generally 10-20%, and the liquid lotion is generally 20-30%, and in the present invention, the effective content of at least one surfactant Not less than 50%, and preferably having a surfactant content of 92 to 97%. '

Different from washing powder and liquid lotion, the present invention selects components which are harmless, environmentally friendly and biodegradable to the human body. For example, in terms of an anionic surfactant, the present invention may be selected from sodium α-alkenylsulfonate, sodium lauroyl sarcosinate, and sodium dodecyl sulfate. In terms of cationic surfactants, the present invention may be selected from the TA101 softener (bisoctadecyldimethylammonium chloride). In terms of nonionic surfactants, the present invention may be selected from fatty alcohol amides and plant erucamide slip agents. In the case of inorganic auxiliaries, sodium hydrogencarbonate, succinic acid, sodium perborate, sodium percarbonate may be used in the present invention. In terms of functional auxiliaries, proteases, herbicides, HQS proteins, flavors and the like can be used in the present invention. In the present invention, the application of succinic acid, polyvinylpyrrolidone, sodium lauroyl sulfonate, TA101 softener, HQS natural protein and herbicide component on the washing fabric is the first case, in washing powder and liquid lotion. Not used. The invention also relates to the first application of DRIETNE collagen and niacinamide components in skin care solid detergent tablets.

Traditional detergents often use decontaminating components, and the selection criteria are often components that combine degreasing and detergency. Such components are just prone to damage various fibers, and all the traces of lanolin (about 0.3 to 1.5%) contained in fibrous collagen and even natural cashmere and wool are washed away from the fibers, thereby seriously damaging the fabric fibers. In fact, modern people's clean and hygienic habits have changed dramatically. From monthly wash to weekly wash to daily wash, how to choose a mild wash product that cares for fabric fibers is already a new technical requirement. It has been found that the combination of sodium α-alkenyl sulfonate and sodium lauroyl sarcosinate can achieve the goal of mild washing and decontamination without fat loss. Sodium lauroyl sarcosinate is seven times more mild than sodium lauryl sulfonate SLES, but it is more potent and has an inhibitory effect on bacteria. Using the above components, the pH of the washing liquid can be stabilized between 5 and 7.5. Thus, a neutral acid neutral wash environment protects human skin and fabric fibers. After washing, the fabric fibers are elongated, strong, and free from any damage, and have a special effect of preventing fiber pilling and anti-scalding.

The process for preparing a solid synthetic detergent of the present invention is:

First, the boiling spray is granulated in one step. At 60 ° C, the liquid lotion is changed to a fog state, and uniformly sprayed onto the group-bound components to achieve the effect of the surfactant-coated inorganic auxiliary agent. During the spraying process, no chemical reaction occurs in each component, and the surfactant is formed into a film-coated inorganic auxiliary agent to form fine particles having an empty capsule structure at 15 to 25 °C. In the present invention, the mixed components obtained in accordance with this step are each RO-l.

Second, at 70 ° C, small particles or powder components containing or not containing RO-1 are put into a vacuum dryer for drying and mixing, and then granulated by dry granulation. The prepared granules are named RO- 2.

Third, under 40 ° C, small particles or powder components containing or not containing RO-l, RO-2 are vacuum-dried and mixed, and then granulated by dry granulation. The prepared granule composition is named RO- 3.

Fourth, under 30 ° C, small particles or powder components containing or not containing RO-l, RO-2, RO-3 are vacuum-dried and mixed, and then granulated by dry granulation, the prepared particulate components Name it RO-4.

Fifth, at or below 50 °C, select some or all of RO-l, RO-2, RO-3, RO-4, or add additional components for vacuum drying and mixing, and then press-form at high speed under normal temperature conditions. The solid synthetic detergent of the present invention is used.

In terms of process, the present invention overcomes the prejudice that the washing component can be pressed into a solid block or a sheet by mixing the powder into a powder. It has been found that the technical prejudice cannot produce a solid synthetic detergent having a smooth surface, a stable physical structure, and easy demolding, and The technical object of the present invention in terms of disintegration and sustained release cannot be achieved, and a preferred technical route of at least 70% by weight of particles mixed with up to 30% by weight of the powder and then pressed into a solid block or sheet is found.

In addition, the present invention employs a water-soluble surfactant and also uses polyvinylpyrrolidone as a disintegrating agent. Polyvinylpyrrolidone is a polymeric PVP that inhibits the migration of dyes in solution. The invention also selects the octadecyldimethylammonium chloride component, which has good softness to the fiber fabric, can make the fabric soft and fluffy, has a good old feeling and a good feeling. It can also improve the anti-static properties of cotton, nylon, wool and synthetic fibers, so that the ironing clothes have no trace and prevent the fibers from pilling. The invention also utilizes the oxygen release and solubilization function of carbon monoxide and boron peroxide active oxygen. In the present invention, succinic acid is mixed with the α-alkenyl sulfonate nano component to improve the disintegration and washing effect. In the present invention, a polymer chelating dispersant and disodium diamine tetraacetate are used to soften the water quality and to increase the water solubility. The present invention can also use a mixed component of a fatty alcohol amide with sodium hydrogencarbonate, sodium lauryl sulfate, and betaine coconut glucoside to improve dissolution and washing performance.

The solid synthetic detergent prepared according to the invention can quickly disintegrate the washing and washing components under the water temperature environment of 20~40 °C, and wash with 1.5-5 g of single solid synthetic detergent. Net one-piece adult down jacket. The single solid synthetic detergent required to clean a single adult sweater, cashmere underwear, cotton underwear, etc. can be less than 1.5 grams.

Specifically, the components used in the present invention, and their compatibility and preparation methods are detailed as follows: 1. Anionic surfactants

The molecular structure of the water-soluble surfactant has an asymmetrical, polar character. The molecule has both a hydrophilic group and a lipophilic group. The hydrophilic group has a carboxyl group, a sulfonic acid group, a sulfate group, an ether group, an amino group, a hydroxyl group and the like, and is an atomic group which is easily soluble in water or wetted by water. The lipophilic group has affinity with oil, and is commonly used as a hydrocarbon group. Surfactants can be classified into anionic surfactants, cationic surfactants, zwitterionic surfactants, nonionic surfactants, mixed ionic surfactants, and the like, and can be used in the present invention. Among them, anionic surfactants are mainly: First, higher fatty acid soap: R-COONa, can be used as detergent and emulsifier. Second, alkyl sulfate: R-OS03Na, can be used as detergent and foaming agent. It has good stability in hard water. The solution is neutral or slightly alkaline. It is the main raw material of liquid lotion. Third, the alkyl sulfonate: R-S03Na, different thiol chain lengths show different surface activities, according to which can be divided into emulsifiers, wetting agents, penetrants, foaming agents, defoamers, etc., widely used For liquid lotion. Fourth, alkylamide betaine: It is an anionic surfactant synthesized from amino acids. Its formula is RCONHR'COONa, which produces more foam and is stable, and has low irritation. It is suitable for baby shampoos and oral cleansers. Fifth, alkyl phosphates: R-OP03Na, with emulsification, defoaming, antistatic, thickening. Depending on the size of the solid synthetic detergent and the disintegration and washing function requirements, the present invention is preferably sodium a-alkenylsulfonate, sodium lauroyl sarcosinate or sodium decylsulfate as an anionic surfactant.

Sodium a-alkenyl sulfonate has excellent water solubility and high efficiency of decontamination, and the effective content can be as high as 90 to 97%. In the present invention, the sodium α-alkenylsulfonate and the succinic acid are mixed and granulated with each other, which can greatly improve the decontamination ability and improve the water solubility of the solid synthetic detergent. This is because the combination of succinic acid and sodium α-alkenyl sulfonate produces a synergistic decontamination effect and also enhances the disintegration effect. The composition of sodium α-alkenylsulfonate is complicated, mainly olefin sulfonate, hydroxydecyl sulfonate, and a small amount of disulfonate. When the concentration is 40% or more, the adhesive is easy. It is acid and alkali resistant and insensitive to hard water. Its biodegradability is good. It usually takes only five days to biodegrade. It is less irritating, less toxic, and the fabric feels good after washing, which can prevent the powdery detergent from agglomerating. It has good penetration and wettability is the strongest with Cl ₂ . Sodium α-alkenylsulfonate can be used as a heavy duty detergent, a wool detergent, a hand washing agent, and the like. Sodium α-alkenyl sulfonate has good low-temperature decontamination and stain removal performance in a phosphorus-free, carbonate-containing detergent, and is resistant to hard water. It is characterized by excellent wettability, detergency, good foaming power, foam Stability, emulsifying power; Very soluble in water, strong calcium soap dispersing power, hard water resistance; Good biodegradability, mild to skin; Good compatibility; Suitable for sodium α-alkenyl sulfonate The washing effect is delicate, feels good, and is easy to rinse. ·

Sodium lauroyl sarcosinate is generally a colorless, clear liquid. It is derived from natural fatty acids and Ν-methylglycine and has the function of conditioning fabric fibers. It is characterized by foaming and stabilizing foam, and can reduce the inhibitory effect of other conditioners on foam; The surfactant is compounded to increase the activity and reduce the irritation of the product; the maximum surface activity is obtained when the pH value is 4 to 7, which can show a strong bactericidal effect; the dissolved lotion can be stabilized, and the transparency is increased. Sense; in the skin care products can form a layer of hydrophobic protective film to protect the skin from harmful substances, to prevent the loss of skin moisture. It also has excellent biodegradability and is suitable for storage and use between 10 ° C and 49 ° C. In general, it is an anionic surfactant which is powerful but extremely mild in nature, and in the present invention, its active ingredient content can be as high as 95%. In the preparation process of the invention, it is mixed with the cationic TA101 nonionic slip agent (bisoctadecyldimethylammonium chloride) and HQS protein in the formulation under low temperature vacuum drying, and the components are mutually contained and maintain their respective functions, suitable for Low temperature mixing and tableting, preferably do not participate in dry granulation.

Sodium decoxide sulfate is an anionic emulsification, decontamination, and foaming agent with a suitable pH of 6-7. In the present invention, it can be used in combination with the above two anionic surfactants.

Second, cationic surfactant

Cationic surfactants generally do not have detergency, but are used in the case where the fabric fibers have a cationic charge, such as silk and wool fabrics, which are washed in a weakly acidic solution, and the cationic active agent has a good washing effect. It has good bactericidal ability, can adsorb on the solid surface and significantly reduce the friction coefficient of the fabric fiber. It can be used as a fabric softener, and can also be used as leveling agent, fixing agent, insecticide and antistatic agent. It is generally not directly compatible with anionic surfactants, and there is no precedent for the direct compatibility of anionic and cationic surfactants in detergents and liquid lotions. The main cationic surfactants are: First, quaternary ammonium salts: mainly used as softeners, antistatic agents, insecticides, demulsifiers, etc., non-toxic and odorless, non-irritating to the skin. Second, pyridine halide: It has the ability to kill typhoid bacillus and Staphylococcus aureus, and is used as a detergent disinfectant in food processing, restaurants, farms, swimming pools, etc. Third, imidazoline: It is a typical cyclic amine compound, mainly used as a hair moisturizer, conditioner, fungicide, antistatic agent, fabric softener, and the like. Fourth, alkyl phosphate substituted amine: can be used as an emulsifier, conditioner and antistatic agent.

A preferred cationic surfactant of the invention is TA101 softener (double 18 fluorenyl) Methyl ammonium chloride). It can be used as antistatic agent, fabric softener, disinfectant, asphalt emulsifier, acrylic fiber leveling agent, fiber conditioner and dye additive. In the present invention, it can be used as a component of mixed granulation to effectively improve the washing effect. Dioctadecyldimethylammonium chloride has good compatibility with cationic, nonionic surfactants or dyes, and should not be compatible with anionic surfactants, dyes or auxiliaries. In view of this, the preparation process of the present invention selects octadecyldimethylammonium chloride to avoid mixing with anionic surfactants, dyes or auxiliaries, and avoids the manner and time of release of the active ingredients. Open anionic surfactants, dyes or auxiliaries.

Third, nonionic surfactants

Nonionic surfactants are not ionic in aqueous solution, have high stability, are not affected by acids and bases, and are compatible with other types of surfactants. It is easily soluble in water, stable to acids and bases, has no binding to fibers, is easy to clean after use, and can be used in combination with cationic and anionic surfactants. In medium, acid and alkaline solutions, it has good washing action, strong emulsifying power, excellent decontamination, emulsifying, dispersing, wetting, solubilizing and anti-reprecipitation, and generally has antistatic effect. It has generally less foam and is suitable for making low foaming detergents. Nonionic surfactants mainly include fatty alcohol polyoxyethylene ethers, alkylphenol ethoxylates, ester types, fatty amines and the like.

Preferred fatty alcohol amides are the invention. It has strong detergency, foaming power and soft, soft fabric. In the preparation process, it can be mixed with other liquid essences, and a hydrocarbon spray or the like is coated with a boiling spray, coated, cooled, granulated, and then mixed with other components and then pressed at a high speed. The process can improve the detergency and dissolving power of the lotion. The plant erucamide slip agent can also be used as a nonionic surfactant for granulation and tableting.

Fourth, inorganic additives

Inorganic auxiliaries such as succinic acid, sodium hydrogencarbonate, sodium perborate, and sodium percarbonate may also be used in the present invention. For example, succinic acid has good intumescent disintegration performance, and can also be used as a detergent builder to soften fibers, disinfect and sterilize. The invention can use the sodium α-alkenyl sulfonate and the succinic acid to contain the granules, and preferably the succinic acid is coated with the succinic acid to prevent succinic acid and sodium bicarbonate from prematurely foaming. Teng reaction. Moreover, it is preferred in the present invention that the succinic acid content exceeds twice the succinic acid content required for the effervescent disintegration chemical reaction. This greatly increases the contact speed and probability of the components required for effervescence in the wash water, thereby greatly increasing the disintegration rate of the solid detergent. In addition, sodium bicarbonate has an intumescent disintegration effect, as well as a builder and promotes powder granulation, and is a main adsorbent in which a liquid component is combined into a solid. It can be selected in a plurality of granulation steps. In the preparation process of the present invention, a liquid surfactant package in which sodium hydrogencarbonate is formed into a film by a plurality of sprays is preferred. After granulation, the mixture is granulated. This allows the effervescent disintegration reaction of sodium bicarbonate with succinic acid to occur in a controlled stage and environment. Percarbon, sodium perborate has oxygen release, solubilization, disintegration, disinfection, and bleaching fabrics to make it bright.

In addition to the above effervescent disintegrating materials, other types of disintegrants may be used in the present invention. The disintegrants which are suitable for use in the present invention can be classified into the following types: a swelling type disintegrating agent, an effervescent type disintegrating agent, a substance having a high solubility, a substance which increases the capillary density, and the like. Swelling disintegrants mainly include: inorganic swelling disintegrants such as bentonite, clay, etc.; organic substances such as starch, cereals, corn, rice, potato starch, starch derivatives, carboxymethyl starch, starch sodium glycolate; , such as beech cellulose, beech-sulfite cellulose, cotton cellulose, pine cellulose, and other kinds of cellulose cellulose derivatives, sodium carboxymethyl cellulose, crosslinked modified cellulose, microcrystalline Cellulose, synthetic organic polymer, polyethylene glycol, crosslinked polyvinylpyrrolidone, and the like. Polyvinylpyrrolidone is preferred as the particle disintegrating agent in the present invention. It is insoluble in water, but has a high water absorption capacity, and the solid synthetic detergent of the present invention can rapidly disintegrate into small particles as it rapidly swells. .

For the effervescent disintegrant, the present invention is not limited to the above components, and may include various weak acids or acid salts in combination with an alkali metal carbonate or a hydrogencarbonate such as citric acid, malic acid, tartaric acid and the like. Further, a highly soluble substance, a substance which increases the capillary density, and the like can also be used as the disintegrating agent of the present invention. For example, Table 1 below describes the water solubility of a partial disintegrant. Among them, urea has high water solubility and is inexpensive, and has been used as a disintegrating agent for washing powder compacted blocks. However, due to the lack of innovation in component selection, compounding methods, and manufacturing methods, and the bulkiness, fluffiness and brittleness, the product has basically disappeared from the market. Depending on the mode of release of the components and the time requirements, the present invention may employ one or more types of disintegrants to modulate the dissolution and disintegration of the solid synthetic detergent.

Table 1 Comparison of water solubility of some substances

Material water solubility ( g/100g )

Sodium citrate dihydrate 72

Potassium carbonate 112

Urea is greater than 100

Sodium acetate (anhydrous) 119

Sodium acetate trihydrate 76

Sodium acetate heptahydrate 71

Potassium acetate is greater than 200 The invention also has the following components: TA101 softener, which makes the fabric soft, anti-static, anti-pilling, and anti-aging after washing; HQS protein can supplement and care for damaged fibrin, prevent pilling and resist Static electricity, improve the gloss of the fabric, restore the texture of the fiber surface, and prevent the ironing marks; Plant erucamide slip agent can improve the smoothness of the fabric; remove the mites, eliminate the mites, and ensure the fabric fiber is good for human health. Wave low-temperature protease, which can biologically soften and polish fabrics to remove specific stains; flavor, can remove fabric odor, and give the fabric a pleasant fragrance after washing.

From the perspective of commercial innovation, the solid synthetic detergent of the present invention can be made into a spherical shape, an oval shape, an elliptical shape, a regular square shape, a long cube shape, a sheet shape, a heart shape, a cylindrical shape, a tipless cone shape, and an animal-like animal. Shape, imitation cartoon character shape, imitation trademark shape or imitation character shape. In addition, for other commercial purposes, at least one surface of the solid synthetic detergent may have a raised or recessed pattern, a security mark, an eco-label, a product description, a safety statement, a trademark, a trade name, a corrugation, a pattern or a picture. In order to provide colored text or graphics or drawings on a solid synthetic detergent, a part of the particles, a part of the surface or the entire surface of the solid synthetic detergent may be coated with a pigment, a dye or other colorant.

The invention further relates to the use of a solid synthetic detergent in a washing machine, wherein the detergent is placed in tap water prior to electrolysis. This detergent can discard large amounts of anionic, nonionic surfactants and can increase the amount of detergent builder and cationic surfactant. In addition, the solid synthetic detergent can also be placed in alkaline water or acidic water after electrolysis. In order to improve the washing effect, the content of anionic surfactant, nonionic surfactant or zwitterionic surfactant in the detergent charged with alkaline water. Relatively high, the amount of cationic surfactant in the detergent charged with acidic water is relatively high.

By adjusting the amount and distribution of the disintegrant, the solid synthetic detergent can be disintegrated after the electrolyzed water comes into contact with the object to be cleaned, or substantially disintegrated before the electrolyzed water comes into contact with the object to be cleaned. From the viewpoint of preliminarily controlling the disintegration effect, in the multicomponent particles of the solid synthetic detergent, the disintegrating component may be close to the surface or core of the particulate matter. Further, in order to prevent the solid detergent from being worn and damp, the solid synthetic detergent of the present invention can be added with a coating which increases the hardness and moisture resistance. The use of succinic acid, polyvinylpyrrolidone, sodium lauroyl creosyl sulfate, TA101 softener, HQS natural protein, and herbicide in the preparation of solid detergents was found by searching. Therefore, the present invention should also cover these technical solutions for use.

In addition to being able to overcome the above-mentioned technical biases in the development of solid detergent products by scientific research and the commercial community, in addition to being able to solve the above-mentioned technical problems encountered in the development of solid detergent products by scientific research and business, the present invention also has the following innovations: First, a component which disintegrates, has functions such as washing, washing, sterilization, and care after dissolution is preferred as a disintegrating agent. The simple disintegration component increases the weight and volume of the solid detergent without significantly improving the washing effect. It is preferred to disintegrate, dissolve, post-wash, sterilize, care, and the like, which reduces the weight and volume of a single detergent for a single piece of laundry. This preferred mode is one of the innovations of the present invention.

Second, completely remove the soap, detergent, liquid surfactant, surfactant components, compatibility, preparation. In addition to surfactants, the present invention utilizes a unique technical design in the selection, compatibility, and preparation of the builder components. For example, in accordance with the micro-washing requirements of solid detergents, the present invention has selected highly effective, highly active, and versatile surfactants by extensive compounding tests. Among them, solid surfactant components suitable for mild and environmentally friendly washing are more common. In addition, through trial and error, the present invention opens up new components in which yin and yang ions can be effectively compounded. In the disintegration of the main washing component and in the surfactant, the effective content can be as high as 92-99.8%. For example, in the following ratioing scheme for 200-800 grams of laundry, the active ingredient content of each of the main base washing components is more than 92%, the weight of the monomer detergent is not more than 3 grams, and the volume is not more than 1 cubic centimeter:

Main wash component 45-55%:

a. Efficient washing components:

1 sodium α-alkenyl sulfonate 10-30%,

Sodium 2-decylsulfonate 3-30%;

b. Mild detergent components:

1 month lauroyl sarcosine sodium 3-10%,

2 alcohol ether carboxylate 1-2%;

c. Inorganic washing:

Sodium bicarbonate 10-30%;

Washing detergent components 5-7%:

a. Polymer chelating dispersant 445G0.3-5%,

b. fatty alcohol amide 1-5%;

c. sodium edetate 0.1-0.3%

Functional washing component 6-10%:

a. Wave low temperature protease 0.6_ ² %,

b. In addition to tincture 0.1-0.3%,

c. Plant-type erucamide slip agent 1-3%,

d. TAlOl softener 3-15%, e.HQS natural protein 0.2-0.5%;

Disintegration and dissolution assisted sterilization components 30-40%:

a. succinic acid 12-30%,

b. sodium percarbonate 5-15%,

c. sodium perborate 5-8%,

d. polyvinylpyrrolidone 0.2-3%,

e. Fragrance 0.1-1%.

Third, the combination of specific components by boiling spray coating and then granulation by low temperature drying is an innovative process proposed by the present invention. The process solves the technical difficulties of adding liquid surfactants, fragrances, etc., and coats different effervescent components with this technique to prevent acidic and alkaline components from producing inorganic salts under undesired conditions and environments.

Fourth, the detergent of the present invention can effectively protect the internal components from decay, escape, or other unnecessary physical or chemical changes by the solid dense compact structure. Under normal circumstances, the shelf life of the opened washing powder is only a few months. Unsealed liquid lotions have a shorter shelf life. In contrast, the test proves that the solid synthetic detergent of the present invention can be exposed to a normal temperature and a normal humidity environment for at least three years, and the solid synthetic detergent coated with the coating has a longer shelf life.

The aspects of the present invention that overcome the deficiencies of the prior art in the field of soap and their effects are reflected in the following aspects:

First, soap consumes a lot of oil. The invention does not require the consumption of grease. Second, soap washing is poor. When the soap encounters minerals in hard water, it will chemically react to produce powdery scum, which is easily attached to the clothes and affects the cleaning effect. The present invention does not have this disadvantage. Third, the versatility of the soap is poor. Soap making requires the use of large amounts of caustic soda, which makes the soap alkaline and corrosive, not suitable for washing silk, wool fabrics, and certain chemical fiber fabrics. The invention is suitable for gentle washing of various fabrics. Fourth, the quality of soap is difficult to guarantee. For example, if there is too much hard oil in the soap and the freezing point is high, the product is prone to cracking and squashing, and the washing performance is seriously degraded. The present invention does not have this disadvantage. Fifth, soap has a pungent smell. The present invention does not have any off-flavors, especially unpleasant odors. The invention may also be formulated as an odorless solid wash block or as a scented lotion. Sixth, soap can irritate the skin. The sodium hydroxide content of the soap is usually high, which makes the soap body alkaline and corrosive. The present invention uses a weak base, a weak acid, a neutral problem to wash, and generally does not irritate the skin. Seventh, soap is not easy to measure. Soaps are generally not used by automatic disintegration, dissolution, and are often applied to the surface of the textile by mechanical friction. How much soap is used in a single piece of textile, which is completely unmanageable Measurement standard. In the present invention, a solid synthetic detergent monomer is preferably used to wash a piece of clothing, which is simple to administer and accurate in metering.

(3) Beneficial effects

The invention overcomes the deficiencies of the prior art in the field of detergent powder and its effects are embodied in the following aspects:

First, the washing powder is highly degreasing. The invention is suitable for gentle washing, basically does not degrease, and does not damage the skin. Second, washing powder wastes water and electricity. Washing powder generally produces a lot of foam, and it takes a lot of water to rinse the laundry, which is a waste of water and electricity. The present invention has less foaming, and basically does not require rinsing for silk woven fabrics, cashmere fabrics, wool fabrics, etc., and rinsing other laundry materials is also rare. Third, the washing powder is prone to residues, especially those that are damp or pressed and agglomerated, and the residue is more common and obvious. The solid lotion of the present invention will gradually disintegrate and will not remain. Fourth, the washing concentration of the washing powder is not easy to control, and the washing effect is poor. The invention enables the user to control the washing concentration more accurately and achieve an excellent washing effect. Fifth, the washing powder has a low density, and the plastic loading device is very bulky. After being damp or squeezed, the washing powder tends to agglomerate and affect the washing effect. The lotion of the present invention has a high density, and conventional extrusion, beating, moisture, and the like do not affect the physical and chemical properties of the lotion of the present invention. Sixth, washing powder is not easy to measure. The volume and density of the washing powder are not easily controlled, which is mainly caused by the preparation process. Factors such as detergent slurry concentration, slurry pressure, gun diameter, inlet air volume, airlift volume, and post-mixing may affect the volume and density of the detergent, making it difficult to measure the amount of laundry powder required for a single piece of clothing. Moreover, due to the difference in particle specific gravity, the distribution of enzymes, bleaches, zeolites, etc. in the loose detergent particles is not uniform. Even if the user accurately measures the amount of detergent powder to be dispensed in a single washing task, the content of each component, such as detergent, detergent auxiliaries, etc., is easily deviated from the actual required value. The solid lotion of the present invention securely encapsulates each of the wash components corresponding to a particular wash task in a detergent monomer, eliminating the aforementioned drawbacks of detergent.

Seventh, after the opening, the washing powder is easily deteriorated. In the present invention, 3⁄4 of the solid lotion is encapsulated in a high-density compacted washing monomer, and a moisture-proof, pressure-proof, abrasion-resistant coating is applied on the outside, which is not easily deteriorated. Eighth, the versatility of washing powder is poor. Washing powder is suitable for washing cotton, linen, chemical fiber and its blended fabric. However, washing powder is generally alkaline, which denatures proteins and causes damage to hair, silk, and the like. Therefore, most washing powders are not suitable for washing wool, silk fabrics or their blended fabrics. The solid lotion of the invention is especially suitable for washing wool, cashmere, silk or a blended fabric thereof, and can also wash various other fabrics such as cotton and hemp, and has good versatility. Ninth, the time during which the components of the washing powder function is not easily regulated. this invention According to the fiber characteristics and the decontamination principle, the mixing, granulation and coating relationship between the components of the solid lotion are appropriately set, thereby setting the manner and sequence of dissolution and release of each component, which can greatly improve the washing effect. However, the physical structure and preparation process of the washing powder does not allow people to make such settings.

The invention overcomes the technical difficulties of the solid detergent field and its effects are embodied in the following aspects:

First, controlling the dissolution rate of the solid detergent in combination with the temperature conditions and the requirements of the washing process; the present invention is based on the consideration of the washing temperature conditions and the requirements of the washing process, by selecting the components, the compatibility of the components, and the group of the solid lotion surface. The disintegration ability, the concentration of the disintegrating component on the surface of the solid lotion, and the mixing and granulation combination between the components solve the technical difficulty. Secondly, the preparation and molding of the granulation and the solid detergent are carried out in combination with the manner and time of releasing the components; the present invention selects the manner, time, sequence, etc. of the release of the components by repeated trials of artificially placing different components. In order to achieve such a selected combination, the present invention solves the above technical problems by designing corresponding compounding, group mixing, group granulation, tableting, and coating coating measures for each component. Third, according to the type and degree of washing objects and dirt targeted by a single detergent, designing reasonable components, ratios, and processes; by statistically analyzing the fiber type, volume, weight, and type distribution of the fabric, the solid washing of the present invention The above-mentioned technical problems are overcome by designing the amount of each component, preferably for a single piece of fabric, and then preparing the laundry by a special process. Fourth, the solid washing and fabric conditioning properties are integrated; the solid lotion of the present invention incorporates a conditioning component to enable gentle laundering and effective conditioning of the fabric. Fifthly, the solid detergent is applied to a hand-washing effect which does not hurt the hand; the invention has low alkalinity, can also be neutral or weakly acidic, has no degreasing and corrosive components, and can be added to the components for skin care, Does not hurt the effect of the hand. Sixth, a new technical viewpoint of injecting a natural biological extract protein into a solid washing material to replenish and remedy the damage of the fabric fiber; the present invention encapsulates the natural protein into a solid monomer to protect it from inactivation and deterioration, first A gentle wash target for the maintenance of fabric fibers was achieved.
