Primary Examiner-Stanley J. Friedman Attorney, Agent, or Firm-Hammond & Littell [5 7 ABSTRACT A hair cosmetic preparation containing the acylation products of protein aminolyzates which have been prepared by reacting natural proteins with diand/or poly-amines containing 2 to 10 carbon atoms and containing additional N-hydroxyalkyl groupings.

9 Claims, No Drawings HAIR COSMETIC PPARATION PRIOR ART It is known to add modified proteins to cosmetic preparations, especially to hair treatment compositions. Thus, for example, acylated or sulfonated protein hydrolyzates or aminolyzates which have surface-active properties are used in hair shampoos or hair waving preparations. Protein hydrolyzates, which are obtained by alkaline hydrolysis or enzymic decomposition of natural proteins, have previously been extensively utilized as effective ingredients of the protein type in hair treatment compositions. The capacity of these products to be substantially absorbed by the hair is however relatively small, so that relatively high concentrations of peptide derivatives are necessary in the treatment compositions in order to obtain useful results. In addition to this, the absorptive capacity is strongly dependent on pH, as well as upon the relationships between the various components of the respective formulations; and these relationships are not yet clearly understood.

OBJECTS OF THE INVENTION It is an object of the present invention to overcome all of the above described disadvantages by providing a hair cosmetic preparation containing modified protein aminolyzates.

It is a further object of the present invention to provide a hair cosmetic preparation comprising a composition containing from about 0.1 to by weight of the acylation product of protein-aminolyzates having at least one additional N-hydroxyalkyl substituent, said protein-aminolyzate being the reaction product of a natural protein with an amine selected from the group consisting of diamine with 2 to 10 carbon atoms, polyamine with 2 to 10 carbon atoms and the mixtures thereof.

It is another object of the present invention to provide a process for treating human hair comprising applying to said hair an effective amount of a composition containing from about 0.1 to 10% by weight of the acylation product of protein-aminolyzates having at least one additional N-hydroxyalkyl substituent, said protein-aminolyzate being the reaction product of a natural protein with an amine selected from the group consisting of diamine with 2 to 10 carbon atoms, polyamine with 2 to 10 carbon atoms and the mixtures thereof, in an aqueous preparation.

These and other objects of the present invention will become apparent as the description thereof proceeds.

DESCRIPTION OF THE INVENTION The present invention is directed to a hair cosmetic preparation comprising a composition containing from about 0.1 to 10% by weight of the acylation product of proteinaminolyzates having at least one additional N- hydroxyalkyl substituent, said protein-aminolyzate being the reaction product of a natural protein with an amine selected from the group consisting of diamine with 2 to 10 carbon atoms, polyamine with 2 to 10 carbon atoms and the mixtures thereof.

The present invention is further directed to a process for treating human hair comprising applying to said hair an effective amount of a composition containing from about 0.1 to 10% by weight of the acylation prodnet of protein-aminolyzates having at least one additional N-hydroxyalkyl substituent, said proteinaminolyzate being the reaction product of a natural protein with an amine selected from the group consisting of diamine with 2 to 10 carbon atoms, polyamine with 2 to 10 carbon atoms and the mixtures thereof, in an aqueous preparation.

The protein aminolyzates starting materials are known from the literature, and their preparation may be carried out, for example, according to the procedure described in the German Pat. No. 1,959,651. These protein aminolyzates preferably have molecular weights from 300 to 1000.

A preferred method of preparing the proteinaminolyzates used as starting materials in the process and products according to the invention, the protein may be derived from any vegetable or animal proteins, for example glue, gelatin, albumin, collagen, keratin, casein, feather protein, hair protein, cottonseed protein or soya protein. For the aminolysis of such proteins, diamines and/or polyamines with 2 to 10 carbon atoms are used. These amines are preferably those aliphatic amines having the formula:

in which n 2 to 10 and m l to 5 with the proviso that the total number of carbon atoms does not exeed 10. Examples of these preferred aliphatic amines are ethylenediamine, 1,4-diaminobutane, diethylenetriamine, 1,6-diaminohexane, triethylenetetramine, or tetraethylenepentamine.

The aminolysis of the proteins with the abovementioned diamines and/or polyamines may be effected in known way by heating the proteins with at least an equal amount by weight of diamine and/or polyamine under reduced pressure at temperatures between and 200C until an aliquot part of the reaction mixture is soluble in dilute acid.

An especially preferred embodiment for carrying out the aminolysis, which leads to products with improved color quality, comprises adding an amount by weight of water, equal to or greater than the amount by Weight of protein, to an amount by weight of diamine or polyamine which is equal to the weight of protein, heating the amine water mixture to C to C in a protective gas and then introducing the protein therein. The temperature was then, also in presence of protective gas, raised to C. As soon as the reaction product was soluble in acid, water and excess amine which might be present were removed under reduced pressure.

The molecular weights of the aminolyzates from proteins and the above-described diamines and/or polyamines generally lie in the range of 300 to 1000. Preferred starting substances for the process according to the invention are proteinaminolyzates with a molecular weight lying in the range from 350 to 700.

The substances contained in the compositions according to the invention are preparable from the protein-aminolyzates by reacting them with epxoides containing 3 to 24 carbon atoms in the molar ratio 1:(0.5 to 1.5) at elevated temperature and acylating the reaction products. The term acylation products relates to corresponding derivatives of carboxylic acids with 10 to 24 carbon atoms. The N-hydroxyalkyl substituents present in the substances preferably contain 3 to 24 carbon atoms. The acyl substitutent having 10 to 24 carbon atoms may be added thereto by means of carboxylic acids or suitable carboxylic acid esters of corresponding chain length. The amount of the acylating agent should be in the range of about 0.5 to 1.5 mol per mol of protein-aminolyzate used. Examples of suitable epoxides which may be used are: glycide, penteneoxide-l ,2, octeneoxide-2,3, deceneoxide-l,2, dodeceneoxidel ,2, octadeceneoxidel ,2, docoseneoxidel ,2, tetracoseneoxide-l,2 alkylglycidyl ethers in which the alkyl has 7 to 21 carbon atoms.

Examples of suitable acylating agents include for example alkanoic acids of to 24 carbon atoms such as capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, behenic acid, and lignoceric acid, alkenoic acids of 10 to 24 carbon atoms such as oleic acid and erucic acid, hydroxy-alkanoic acids of 10 to 24 carbon atoms such as hydroxy-stearic acid, hydroxy-alkenoic acids of 10 to 24 carbon atoms such as ricinoleic acid, alkadienoic acids of 10 to 24 carbon atoms such as linoleic acid, alkatrienoic acids of 10 to 24 carbon atoms such as linolenic acid, and the mixtures thereof. Preferred are the naturally occurring fatty acids having 10 to 24 carbon atoms. Other suitable acylating agents include caryboxylic acids such as 2-methyl-stearic acid and l-undecenoic acid-1 l.

The acylation may be effected at temperatures between 100C and 150C. A portion of the substances contained in the hair treatment compositions according to the invention can be prepared in an especially simple manner by reacting the abovementioned proteinaminolyzates with a glycidyl ester of a carboxylic acid which contains 10 to 24 carbon atoms in the acyl substituent and which correspond to the above mentioned carboxylic acids, at temperatures of 70 to 150C. According to this procedure the protein-aminolyzates are reacted with glycidyl esters of carboxylic acids of the general formula:

in which R signifies an aliphatic hydrocarbon containing 9 to 23 carbon atoms. The aliphatic hydrocarbon R may be a straight or branched chain and be saturated or unsaturated. Preferably R is a straight chained member selected from the group consisting of alkyl of 9 to 23 carbon atoms, alkenyl of 9 to 23 carbon atoms, alkadienyl of 9 to 23 carbon atoms, hydroxy alkyl of 9 to 23 carbon atoms, hydroxyalkadienyl of 9 to 23 carbon atoms, and alkatrienyl of 9 to 23 carbon atoms, and the mixtures thereof.

The relative proportions of the protein aminolyzate and the glycidyl ester of a carboxylic acid may vary Within specified limits, depending on the type and molecular weight of the aminolyzate used. However, the range of 1 to 3 mol of glycidyl esters per mol of aminolyzate are preferable, since the products produced are more easily dispersible in water/alcohol mixtures.

The temperatures to be used lie in the range of 70 to 150C. Basically the reaction may be carried out without use of a solvent. Since, however, the reaction is strongly exothermic and local overheating influences the color quality of the products, the addition of a solvent in which the aminolyzates are soluble or at least dispersible is preferable. Suitable solvents are, for example, lower alcohols and/or water.

The reaction may be carried out by adding the glycidylester portionwise to the aminolyzate heated to the desired reaction temperature, to which a solvent is optionally added, and thoroughly mixing the reaction material. After the termination of the glycidyl ester addition, heating and thorough mixing of the reaction mixture possibly after increasing the temperature is continued until epoxide oxygen is no longer detectable. The separation of the solvent, which may be present, may be effected by distillation before or during the period subsequent to the reaction.

However no claim is being made to the processes for the preparation of the protein aminolyzate.

In the simplest case, the compositions according to the invention may contain 0.1 to 10% by weight, preferably 0.1 to 1.5% by weight of an aqueous or aqueousalcoholic dispersion of the described substances and in this form may be used, for example, as an after-rinsing preparation. The compositions may be adapted to for other uses, such as for example, hair shampoos, hair dressings, hair setting agents, and would therefore contain the customary components used in the usual proportions in these compositions.

Accordingly, the compositions may contain from 0 to about 50% by weight of surface-active components, usually being the anionic sulfate surface-active compounds such as higher fatty alcohol sulfates, higher fatty alcohol ether sulfates with 3 to 4 ethylene oxide units in the molecule, higher alkylphenol ethoxylated sulfates, monoglyceride sulfates, and also higher fatty acid-protein condensation products,- higher fatty acid sarcosides and higher fatty acid methyl taurides. Also suitable for special preparations are amphoteric surface-active compounds, such as for example, the imidazole derivatives known by the name miranoles. The abovementioned anionic surface-active compounds are present preferably in the form of their alkali metal, such as sodium, and triethanolamine salts and in certain cases such as, for example myristyl alcoholethoxylated sulfate, also in the form of the magnesium salts.

Emulsifying agents which may be present in the compositions from 0 to about 10% by weight according to the invention are soaps of stearic, lauric and oleic acids in the form of their sodium, potassium or alkanolamine salts, as well as the above mentioned anionic sulfate surface-active compounds, and polyol-fatty acid esters, for example glycerine monostearate, propylene glycol monostearate, diethyleneglycol monostearate, some in admixture with anionic emulsifiers, fatty alcohol mixtures in combination with anionic emulsifiers; nonionic emulsifiers such as polyethylene oxide glycol esters, for example polyhydroxyethylene stearate, -laurate or -oleate, polyethylene oxide sorbitan esters, with higher fatty acids, simple sorbitan esters such as sorbitan monolaurate, -oleate, -sesqui-oleate, sterols, polyoxyethyleneglycol esters of higher fatty acids, as, for example the monoand di-laurates, -oleates or -stearates of polyoxyethyleneglycol with molecular weights of 200 to 600; cationic emulsifiers such as lauryl ammonium chloride, cetyl pyridinium chloride, cetyl trimethylammonium bromide, diisobutyl-phenoxyethoxyethyldimethylbenzylammonium chloride, alkyl-dimethylbenzylammonium chloride with 10 to 14 carbon atoms in the alkyl residue, N- (stearylcolaminoformylmethyl)-pyridinium chloride or the like; examples of amphoteric emulsifiers are ethylenecycloimidol -lauryl-2-hydroxyethylene-sodium alcoholate, triethanolamine-B-alanine,

N-laurylaminopropionate, N-lauryliminodipropionate, lauryl-diethyl-triaminoacetic acid, etc.

The usual substances may also be added as thickeners, which are present from O to about 5% by weight, such as, for example, sodium alginates, fatty acid alkylolamides and some partial tylose slimes; also higher molecular weight polyoxyethylene-glycol-monoor -diesters of higher fatty acids, such as stearic acid and lauric acid. In some cases, electrolytes such as sodium chloride or ammonium chloride are also used as thickeners in combination with alkyl polyoxyethylene sulfates.

In specified cases, superfatting agents may also be added to the compositions according to the invention, in amounts of from to about by weight for example polyhydroxyethylated lanoline derivatives, lecithin derivatives or the aiready mentioned alkylolamides, to which a certain oiling action belongs. The latter may also serve as foam stabilizers in shampoos.

The compositions according to the invention may also contain lower aliphatic alcohols as solvents, such as lower alkylols of 1 to 6 carbon atoms for example ethanol or isopropanol. So-called builder components may be added from O to about by weight, such as paraffin, fats, lanolin and wool fat alcohols. Other usual components may be added from 0 to about 7% by weight, such as preservatives, especially formalin, sorbic acid and dehydroacetic acid, 6-acetoxy-2,4- dimethyl-dioxane, esters of p-hydroxybenzoic acid; biogenic substances such as plant extracts and vitamin complexes. Solution aid components may be added from O to about 10% by weight, such as lower alkylene glycols, for example 1,3-propanediol, 1,3- butyleneglycol, diethyleneglycol. Film forming components may be added from 0 to about 2% by weight such as polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymers, polymers of the acrylic acid series, dimethylhydantoinformaldehyde resins, polymers of the 2-alkyl-2-oxazoline series. Acid adjusting agents, especially fruit acids, such as citric acid and/or lactic acid may be added from 0 to about 2 by weight.

Relatively small contents of the protein-aminolyzate derivatives described above impart to hair cosmetic preparations of various compositions a good hair conditioning and structure-improving activity. Generally from about 0.1 to 10% by weight, preferably 0.1 to 1.5% by weight, based upon the total composition weight, is sufficient. For special preparations, which are to be used particularly for the treatment of substantially damaged hair, higher concentrations thereof could be used.

The following examples are merely illustrative of certain uses of the products of the present invention and include hair shampoos, hair dressings, hair after-rinsing compositions and hair setting compositions with a content of the above-mentioned protein-aminolyzate derivatives and the following composition, without being deemed limitative of the present invention in any manner thereof.

The following examples are further illustrative of the present invention without being deemed limitative in any manner thereof.

Protein Derivative A A mixture of 1 kg of diethylenetriamine and 2 kg of water was heated in a round-bottomed flask to 90C. 1 kg of casein was added with stirring during a period of half an hour, and then the reaction temperature was raised to l 10C. The heating was continued until an aliquot part of the reaction mixture was soluble in dilute acid. Water and excess amine were distilled off in vacuo. The protein-aminolyzate product was obtained in the form of a paste after the cooling thereof, and it had an average molecular weight of 550. This proteinaminolyzate was then reacted with about an equimolar amount of hexadeceneoxide-l,2 at a temperature of about C. Then methyl stearate was added in about an equimolar amount and was reacted therewith at 130C under reduced pressure.

Protein Derivative B Utilizing a procedure analogous to that described for obtaining Protein Derivative A, the reaction product of a protein-aminolyzate from gelatin and diethylenetriamine (mol. wt. 510) with hexadeceneoxide-l,2

and methyl stearate in about equimolar proportion, was produced.

Protein Derivative C Utilizing a procedure analogous to that described for obtaining Protein Derivative A, the reaction product of a protein-aminolyzate from albumin and diethylenetriamine (mol.wt. 520) with hexadeceneoxidel ,2 and methyl stearate in about equimolar proportion, was produced.

Protein Derivative D Utilizing a procedure analogous to that described for obtaining Protein Derivative A, the reaction product of a protein-aminolyzate from casein and tetraethylenepentamine (mol.wt. 590) with hexadeceneoxide-l ,2 and methyl stearate in about equimolar proportion, was produced.

Protein Derivative E Protein Derivative F A procedure analogous to that described for obtaining Protein Derivative A was utilized except that the reaction product of a .protein-aminolyzate from gelatin and diethylenetriamine (mol.wt. 385) was reacted at 80 to 90C with glycidyl laurate in the molar ratio 1 :2.

Protein Derivative G Utilizing a procedure analogous to that described for obtaining Protein Derivative F, the reaction product of a protein-aminolyzate from gelatin and diethylenetriamine (mol.wt. 385) with glycidyl oleate in the molar ratio 1:2, was produced.

Protein Derivative H Utilizing a procedure analogous to that described for obtaining Protein Derivative F, the reaction product of a protein-aminolyzate from gelatin and diethylenetriamine (mol.wt. 385) with glycidyl stearate in the molar ratio 1:2, was produced.

EXAMPLE 1 The Protein Derivatives A to H were incorporated in hair dressing compositions of the following recipe:

Wool fat Fatty alcohol Glyeeridc mixture lsopropyl myristate Glyeerine Non-ionic emulsifier Plant extract Cationic emulsifier Protein Derivatives A to H part by weight Swelling agent 0.2 Perfume oil 0.3 Water 75 In order to test the above hair dressing compositions, models with structurally damaged hair were selected.

The hair was washed in each case, brushed and parted in the middle. Then the hair dressing compositions were applied to one half of the head and a blank experiment material (hair dressing composition with omission of the protein derivative but otherwise the same composition) was applied to the other half of the head. After a treatment time of 15 minutes the hair was rinsed with warm water, brushed and the wet combability and the body of the hair were judged.

The hair was wound on rollers, dried and, after removal of the rollers, the curls were tested for firmness and elasticity. The judgments, which in each case were carried out by 10 experienced persons, led to the following results. The body of the hair and the wet combability of the hair were improved by the addition of the Protein Derivatives A to H; the hair dried on rollers was firm as compared with the blank experiment and the curls had an improved springiness.

EXAMPLE 2 Hair rinsing compositions of the following recipe were prepared:

Wool fat 1 part by weight Paraffin oil 1 Glyceridc mixture 2 lsopropyl myristate 2 Fatty alcohol 0.4 Glyccrine l0 Cationic emulsifier 0.5 Protein Derivatives A to H l Swelling Compounds 0.2 Perfume oil 0.5

Water 81.4

The technical application test was effected as described in Example 1; the treatment time was 5 minutes in each case. Ten experienced persons judged the body of the hair, the wet combability, the firmness and behavior of the hair dried on rollers. The hair showed noticeable improvements compared with blank experiments and comparative preparations which contained protein hydrolyzates (Trade names WSP X 250 and WSP X 1000), with otherwise the same composition, instead of the protein derivatives of the present inventron.

EXAMPLE 3 Hair shampoos of the following recipes were prepared:

Example 3(a):

Sodium lauryl ethyleneglycol ethersulfatc [0 parts by weight Fatty acid alkanolamide 4 Protein Derivatives A to H l Sodium chloride 2 Perfume oil 0.3

Water 82.7

Example 3(b):

Sodium lauryl sulfate 20 parts by weight Stearic acid 5 Protein Derivatives A to H l Caustic soda 0.7 Perfume oil 0.3

Water 73 The following experiments were carried out with the above-mentioned hair shampoos in which models with slightly roughened hair were chosen. The hair was wetted with water, parted in the middle and half the head given a preliminary wash with 5 g of the hair shampoo to be tested and the other half of the head with 5 g of a protein derivative-free shampoo with otherwise the same composition. The subsequent washing was then carried out in the same way and the final judging was carried outby 10 experienced persons. In all cases an improvement of the wet combability was found; the dry hair felt slightly firm and heavy. The static charging of the hair was noticeably reduced.

Comparative experiments were carried out with preparations according to Comparative Example 3a, which contained, instead of the Protein Derivatives A to H the same amount of commercial protein hydrolyzates (Trade names WSP X 250 and WSP X 1000). The treated hair showed the same quality as one washed with the above described blank sample.

EXAMPLE 4 EXAMPLE 5 Utilizing a hair setting agent of the following composition:

Copolymcrizatc of 60% by weight vinylpyrrolidonc 2 40% by weight of vinyl acetate parts by weight Emulsificr (non-ionic) 0.35 Plant extract 0.40 Protein Derivative O 0.20 Perfume 0.15 lsopropanol 35.00 Water 6|.90

the following experiments were carried out:

Selected models with normal hair were given a hair washing. After brushing, the hair was parted, one-half wetted with 10 ml of the experimental product and the other half with 10 ml of a blank test sample (preparation of the same composition without protein derivative). The hair was wound on rollers and dried. In all cases the hair had an improved firmness.
