This application is a continuation-in-part of U.S. patent application Ser. No. 10/056,964, filed Nov. 7, 2001 now U.S. Pat. No. 6,642,194, the disclosure of which is incorporated in its entirety herein by reference.
The concept of cleansing and conditioning detersive products has drawn great attention since its launch in the early 1980's. From a technical point, cleansing and conditioning are contradictions, since conditioning has to deposit some ingredients on an object and cleansing has to remove the deposited ingredients from the object. To combine cleansing and conditioning in detersive products means when the product removes the dirt from the object, the product also simultaneously deposits some conditioning ingredients on the object. The conditioning effects depend on the equilibrium between the removed dirt, conditioning ingredient and deposit conditioning ingredients. For hair products, conditioning involves depositing certain agents onto the hair to give it the protection, softness, shine and detangling effects. Less deposition means less conditioning and more deposition means more conditioning or over conditioning.
To achieve proper conditioning formulations, chemists are faced with the challenge of choosing the appropriate conditioning ingredients, the proper ratio of conditioning ingredients to surfactants and methods of incorporating conditioning ingredients into the detersive system to form stable products.
A conditioning ingredient should have the basic characteristic of being water-insoluble, easy to be spread and have some affinities with the application objects. Polysiloxane, such as dimethicone, and derivatives are water-insoluble and are widely used conditioning ingredients. Furthermore, polysiloxanes usually give good hair protection, softening, shine and detangling effects.
The various technical methods for incorporating polysiloxanes, such as dimethicone, into the detersive products have been patented. The focus is on the particle size distribution of dimethicone surfactant emulsion and stability of the shampoo. Smaller particle size means more stability and more deposition to the targeted object.
Although some success has been achieved in being able to incorporate polysiloxanes, such as dimethicones, into detersive compositions, other challenges still remain. It remains a challenge to be able to formulate a stable conditioning/detersive composition, especially when a polysiloxane (e.g. dimethicone) is employed. Considering the regular viscosity of the detersive composition and the relatively lightweight of the conditioning ingredients, it is very difficult to achieve a long-term stability of the products. For example, the products tend to separate with the conditioning ingredients settling on top of the water-detergent solution. Furthermore, it remains a challenge to be able to formulate a clear stable conditioning/detersive composition, especially when the conditioning ingredient is a polysiloxane.
There continues to be a need to have a more stable formulation having a conditioner and a detersive composition. In particular, there is a need to have a clear detersive formulation which comprises a polysiloxane.
The present invention meets this need and provides for a stable, clear detersive composition having a polysiloxane component. In one embodiment, the present invention provides for a clear detersive composition comprising a conditioner. A clear conditioning/detersive composition includes, for example, a conditioning shampoo which is substantially clear.
The term “clear” as used herein means a substantial amount of light may pass through. Alternatively, the term “clear” means transparent or translucent, as opposed to opaque.
In accordance with the invention, a composition comprising an emulsifier component and a polysiloxane component is provided. The polysiloxane component comprises at least one side chain component A having the general formula:
Further in accordance with the present invention, the composition further comprises a detersive component. For example, the composition comprises about 5% to about 60% of the detersive component, about 0.01% to about 10% of the emulsifier component, and about 0.01% to about 10% of the polysiloxane component.
Still further in accordance with the present invention, a method of making a clear shampoo is provided. The method comprises the steps of forming a micro-emulsion of a polysiloxane component, and combining the micro-emulsion with a detersive component. The micro-emulsion is formed by combining a non-ionic emulsifier with a polysiloxane component.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art.
Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
The present invention is, in part, based upon the surprising discovery that a polysiloxane component may be combined with a detersive component to form a clear composition, preferably a clear shampoo. In a broad embodiment, the composition comprises an emulsifier component and a polysiloxane component.
Without wishing to limit the invention to any theory or mechanism of operation, it is believed that a clear composition, for example, a clear shampoo composition, may be produced by combining a detersive component with performed micro emulsion comprising a polysiloxane component. The micro emulsions may or may not remain intact after it is combined with a detersive component.
In one embodiment, a composition of the present invention remains stable (for example remain clear) for about 360 days after manufacturing.
In one embodiment, the micro emulsions are formed by mixing the emulsifier components with the polysiloxane components, preferably in the presence of water. For example, micro emulsion are formed by homogenizing emulsifier components with polysiloxane components in a tank at about 40 to about 70 degrees C. In one embodiment, a homogenizer employed is model number ME 100 LC by Charles Ross and Son, Hauppauga, N.Y. In one embodiment, the ratio (by weight) of the emulsifier component to the polysiloxane component in a micro emulsion is about 1:1, 1:2, 1:3, or 1:4.
In one embodiment, emulsifier components include a non-ionic emulsifier. In another embodiment, the emulsifier components include a non-ionic emulsifier and at least one of an anionic emulsifier and an amphoteric emulsifier. The anionic amphoteric emulsifiers are selected from the anionic and amphoteric surfactants, respectively.

In one embodiment, the composition comprises about 0.01% to about 10% of an emulsifier component, preferably about 0.01% to about 8%, more preferably 0.1% to about 5%, even more preferably 0.1% to about 5%. Preferably, the emulsifier components form micro emulsions with the polysiloxane components.
In one embodiment, the composition comprises about 0.01% to about 10% of a non-ionic emulsifier, preferably about 0.01% to about 8%, more preferably 0.1% to about 5%, even more preferably 0.1% to about 5%. Preferably, the emulsifier components form micro emulsions with the polysiloxane components.
In one embodiment, the composition comprises about 0.01% to about 5% of a non-ionic emulsifier and at least one of about 0.01% to about 5% of an anionic emulsifier/surfactant and an amphoteric emulsifier/surfactant.
In one embodiment, the composition comprises about 0.01% to about 10% of a polysiloxane component. Preferably, the composition comprises about 0.05% to about 6%, more preferably 0.1% to about 5% of the polysiloxane component.
The popularity of polysiloxane, or dimethicone and dimethicone derivatives, in shampoo compositions originate from their chemical and physical properties. There is a weak inter-molecular interaction between polysiloxane molecules and continuing rotation around Si—C and Si—O bonds of the polysiloxane molecules because of the longer Si—C and Si—O than C—C and C—O in regular organic compound. Thus, there is much more space around the silicon atoms and therefore render the polysiloxane excellent spreadbility. Polysiloxane and derivatives also have high refractive index. Furthermore, polysiloxane and derivatives can deliver a smooth feel, detangling and sheen effect to hair.
In one embodiment, the polysiloxane component has the general formula:
In a preferred embodiment, the polysiloxane component has the general formula:
In a preferred embodiment, the polysiloxane component comprises about 2 to about 1000 Si, preferably about 4 to about 500 Si, more preferably about 10 to about 300 Si.
In one embodiment, the polysiloxane component comprises at least one side chain component A having the general formula:
In one embodiment, the cyclic moiety of the side chain component is saturated. In another embodiment, the cyclic moiety is substituted. For example, the a side chain component A of the polysiloxane component may include the general formula:
For example, a side chain component A of a preferred polysiloxane component of this invention has the general formula:
Side chain component A employed in accordance with this invention preferably has a “hindered amine”, or a secondary restricted monoamine function group. Preferably, the molecules can be partially protonated at normal shampoo pH range (pH 4-7). The hindered amine functional group is believed to render several beneficial effects. For example, it is believed that the hindered amine polysiloxane (or dimethicone) has more hair or skin affinity and give more conditioning effects. Furthermore, a shampoo comprising a polysiloxane component with a hindered amine functional group is more stable gives more hair softness, smoothness and shine than a shampoo which does not have a hindered amine group.
In one embodiment, the ratio of the Si to the side chain component A in a polysiloxane component is 1:1, preferably 1:0.1, more preferably 1:0.01, even more preferably 1:0.001.
In one embodiment, every other Si of the polysiloxane component has a side chain component A. In another embodiment, every third Si has the side chain component A. In yet another embodiment, every forth, fifth or sixth Si has a side chain component A.
In one embodiment, a polysiloxane component comprises a set of adjacent Si's of the polysiloxane component having side chain component A followed by a set of adjacent Si's having side chain components which are not side chain component A. See, for example, the molecule M below:
In one embodiment, the polysiloxane component has a viscosity in the range of about 1 cps (centistoke) to about 1,000,000 cps (centistoke). Preferably, the polysiloxane component has a viscosity in the range of about 100 cps to about 500,000 cps. More preferably, the polysiloxane component has a viscosity in the range of about 1,000 cps to about 100,000 cps. For example, the polysiloxane component may have a viscosity of about 3,000 cps to about 4,000 cps, preferably about 3,500 cps.
In one embodiment, the polysiloxane component has a viscosity in the range of less than about 1,000,000 cps (centistoke). Preferably, the polysiloxane component has a viscosity of less than about 500,000 cps. More preferably, the polysiloxane component has a viscosity of less than about 100,000 cps. Even more preferably, the polysiloxane component has a viscosity of less than about 10,000 cps.
In one embodiment, the polysiloxane component has a viscosity in the range of more than about 1 cps (centistoke). Preferably, the polysiloxane component has a viscosity of more than about 1,000 cps. More preferably, the polysiloxane component has a viscosity of more than about 3,000 cps. Even more preferably, the poly siloxane component has a viscosity of more than about 10,000 cps.
The amine contents of the polysiloxane components vary with viscosity. The particular value of amine content corresponding to a certain range of viscosity may be determined readily by one of ordinary skill in the art. The amine content of the polysiloxane component may be about 200 to about 40,000 (ppm, N) at about room temperature.
In one embodiment, the polysiloxane component comprises the molecule M and has a viscosity of about 500 to about 6,000 cps at room temperature. In a preferred embodiment, the polysiloxane component comprises the molecule M and has a viscosity of about 1,000 to about 5,000 cps at room temperature. In a more preferred embodiment, the polysiloxane component comprises the molecule M and has a viscosity of about 2,000 to about 4,000 cps at room temperature. In an even more preferred embodiment, the polysiloxane component comprises the molecule M and has a viscosity of about 3,000 to about 4,000 cps, for example about 3,500 cps at room temperature.
In one embodiment, the polysiloxane component is water insoluble. In one embodiment, the polysiloxane component is a colorless, viscous liquid. In one embodiment, the shelf life of the polysiloxane is up to 12 months from date of manufacture.
In one embodiment, the composition comprises about 0.01% to about 10% of an emulsifier component and about 0.01% to about 10% of a polysiloxane component. In one embodiment, the emulsifier component is a mixture of non-ionic emulsifier and an anionic emulsifier (and/or amphoteric emulsifier). For example, the emulsifier component may comprise more than about 90%, more than about 80%, more than about 50%, more than about 30% or more than about 10% of non-ionic emulsifier.
Preferably, the emulsifier component and the polysiloxane component form a micro-emulsion. For example, an emulsifier component comprising an anionic emulsifier (e.g. Capryeth-3) and a non-ionic emulsifier (e.g. Undeceth-5) is added to propoxytetramethyl piperidinyl dimethicone and water to form a micro-emulsion of propoxytetramethyl piperidinyl dimethicone.
The mixture containing the micro-emulsion may be designated as “phase A”. Phase A may be added to a detersive component, designated as “phase B”, to form a clear composition. A detersive component comprises a chemical or formulation which is effective for cleaning, preferably cleaning hair. For example, the detersive component may comprise one or more of the anionic surfactants or amphoteric surfactants identified herein. In one embodiment, a detersive component may also include emulsifier components, for example the non-ionic emulsifiers above.
In one embodiment, the composition comprises about 5% to about 60% of the detersive component, preferably about 10% to about 50%, more preferably about 20% to about 40%, even more preferably about 20% to about 30%.
A detersive component may further comprise a shampoo additive component. Shampoo additive components include any chemical or formulation that adds to the beneficial qualities of a shampoo. Shampoo additive components include, without limitation, ingredients for boosting foam, protecting the integrity of composition, increasing viscosity, covering the odor of raw material and increasing the attraction of the shampoo. Non-limiting examples of shampoo additive components include alkylamide MEA or alkylamide DEA. Sodium Chloride, preservatives, fragrance and colors.
In one embodiment, the composition comprises about 5% to about 60% (by weight) of the detersive component, 0.01% to about 10% (by weight) of the emulsifier component and about 0.01% to about 10% (by weight) of the polysiloxane component. Preferably, the polysiloxane component comprises a propoxytetramethyl piperidinyl dimethicone.
In one embodiment, the ratio (by weight) of phase a:phase B is about 0.1:99.9, 1:99, 2:98.

The invention is further illustrated by the following exemplar formulations, which are intended as illustrations only. The thermal and physical stabilities have been tested at both ambient and elevated (40° C.) temperatures. Examples 1-7 are the clear detersive formulations. Examples 1-7 use the pre-emulsified microemulsion in the formula; therefore, it is easy to make stable and clear Propoxytetramethyl Piperidinyl Dimethicone detersive emulsion. The composition is obtained by preparing phase A at 60-70° C. and incorporating silicone phase A into phase B at about 40-50° C. for clear detersive composition. The examples 8-11 are the opaque formulations and were made by directly dispersing the hindered amine silicone into surfactant system. The fragrance, preservatives and color are added and then mixing at 40-50° C. afterwards. The pH for inventive detersive composition should be within 4-7 pH ranges. “q.s.” means quantum sufficit, or as much as suffices.
Each of the percentages of the ingredients identified in the Examples below may be individually varied to be higher or lower by about 5% to about 40%, preferably about 5% to about 20%, more preferably about 5% to about 10%, and would still be considered to be within the scope of this invention.
In each of the Examples below, the viscosity of the identified polysiloxane component may be about 1 cps to about 1,000,000 cps (centistoke). For example, the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 1 may be about 2,000 cps; the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 2 may be about 3,000 cps; the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 3 may be about 3,500 cps; the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 4 may be about 4,000 cps; the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 5 may be about 100,000 cps; the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 6 may be about 200,000 cps; the propoxytetramethyl piperidinyl dimethicone (Molecule M) of Example 7 may be about 400,000 cps.
