Hair and skin care composition
View Patent ↗The present invention provides cosmetic compositions that form a durable film or coating on surfaces such as hair or skin. The compositions of the invention comprise one or more anionic silicones and one or more high molecular weight esters, the combination of which provides a durable film. Methods for treatment of hair and skin employing the compositions of the invention are also provided.
1. A composition for forming a film on hair or skin comprising from about 0.05% to about 20% by weight dimethicone PEG-7 sulfate and from about 0.1% to about 10% by weight diisostearyi polyglyceryl-3 dimer dilinoleate.
2. The composition of claim 1 further comprising dimethicone PEG-8 phosphate.
3. A hair care composition comprising:
(a) one or more anionic silicones selected from the group consisting of dimethicone PEG-7 sulfate, dimethicone PEG-7 phosphate, dimethicone PEG-7 phthalate, dimethicone PEG-7 succinate, dimethicone PEG-8 phosphate, and combinations thereof;
(b) one or more high molecular weight esters selected from the group consisting of diisostearyl polyglyceryl-3 dimer dilinoleate, triisostearoyl polyglyceryl-3 dimer triisostearyl trilinoleate, and combinations thereof;
(c) a hair conditioning agent selected from cationic surfactants and quaternary ammonium compounds; and
(d) a suitable vehicle for said hair care composition;
wherein said anionic silicone comprises from about 0.05% to about 20% by weight of the composition and said high molecular weight esters comprise from about 0.1% to about 10% by weight of the composition.
4. The hair care composition of claim 3 wherein said one or more high molecular weight esters comprises diisostearyl polyglyceryl-3 dimer dilinoleate.
5. The hair care composition of claim 3 wherein the anionic silicone comprises from about 0.1% to about 10% by weight of the composition and the high molecular weight esters comprise from about 1% to about 8% by weight of the composition.
6. A method of treating a hair fiber of the scalp comprising applying to said hair fiber a leave-on hair product comprising: (a) one or more anionic silicones selected from the group consisting of dimethicone PEG-7 sulfate, dimethicone PEG-7 phosphate, dimethicone PEG-7 phthalate, dimethicone PEG-7 succinate, dimethicone PEG-8 phosphate, and combinations thereof; and (b) one or more high molecular weight esters selected from the group consisting di-esters of di-acids or tri-esters of tri-acids having a molecular weight of at least 450; with the provisio that said ester is not diisostearyl.
7. The hair fiber of the scalp or eyelashes according to claim 6 , wherein the weight ratio of said one or more high molecular weight esters to said one or more anionic silicones is from about 5:1 to about 1:2.
8. A method of forming a film on a hair fiber comprising applying to said hair fiber a composition comprising:
(1) one or more anionic silicones selected from the group consisting of dimethicone PEG-7 sulfate, dimethicone PEG-7 phosphate, dimethicone PEG-7 phthalate, dimethicone PEG-7 succinate, dimethicone PEG-8 phosphate, and combinations thereof; and
(2) one or more high molecular weight esters selected from the group consisting of diisostearyl polyglyceryl-3 dimer dilinoleate, triisostearoyl polyglyceryl-3 dimer triisostearyl trilinoleate, and combinations thereof;
wherein said anionic silicones comprise from about 0.05% to about 20% by weight of the composition and said high molecular weight esters comprise from about 0.1% to about 10% by weight of the composition.
9. The method of claim 8 wherein said one or more anionic silicones comprises dimethicone PEG-7 sulfate.
10. The method of claim 8 wherein said one or more high molecular weight esters comprises diisostearyl polyglyceryl-3 dimer dilinoleate.
11. The method of claim 8 wherein said one or more anionic silicone comprises from about 0.1% to about 10% by weight of the composition and said one or more high molecular weight esters comprise from about 1% to about 8% by weight of the composition.
12. A method of straightening hair comprising:
(a) wetting said hair;
(b) applying to said wet hair a composition comprising: (i) one or more anionic silicones and (ii) one or more high molecular weight esters having a molecular weight of about 450 or higher selected from the group consisting di-esters of di-acids or tri-esters of tri-acids;
(b) combing or brushing said hair after said composition has been applied; and
(c) drying said hair, optionally by heating said hair;
thereby substantially straightening said hair.
13. The method of claim 12 wherein said hair remains substantially straighter for at least 12 hours following said treatment.
14. The method of claim 12 wherein said hair remains substantially straighter after at least one shampooing or washing.
15. The method of claim 12 wherein said one or more anionic silicones comprises an anionic silicone selected from the group consisting of dimethicone PEG-7 sulfate, dimethicone PEG-7 phosphate, dimethicone PEG-7 phthalate, dimethicone PEG-7 succinate and dimethicone PEG-8 phosphate, and combinations thereof.
16. The method of claim 12 wherein said one or more high molecular weight esters comprise a high molecular weight ester selected from the group consisting of diisostearyl polyglyceryl-3 dimer dilinoleate, triisostearoyl polyglyceryl-3 dimer dilinoleate, diisostearyl dimer dilinoleate, triisostearyl trilinoleate, diisostearyl dimer dilinoleate, and combinations thereof.
17. The method of claim 12 where said one or more anionic silicones comprises dimethicone PEG-7 sulfate and said one or more high molecular weight esters comprise diisostearyl polyglyceryl-3 dimer dilinoleate.
