Hair care compositions
View Patent ↗Hair care compositions are disclosed which comprise a silicone polyurethane polymer, an ester, and a fluorosilicone. The compositions are useful for improving color retention of artificially colored hair.
1. A method for improving color retention of artificially colored hair comprising applying to hair that has been dyed with an oxidative dye, after it has been dyed but prior to a first shampooing, a composition comprising
(i) a silicone polyurethane polymer, comprising Bis-hydroxypropyl Dimethicone/dicyclohexylmethane-4,4′-diisocyanate (SMDI) copolymer (INCI)
(ii) a film-forming ester comprising a tri-ester of a C 6 -C 72 tricarboxylic acid with a branched C 8 -C 24 alcohol;
(iii) fluorosilicone, and
(iv) a vehicle;
wherein said silicone polyurethane polymer, said film-forming ester, and said fluorosilicone are dispersible but not soluble in said vehicle.
2. The method according to claim 1 , wherein said composition comprises from 1 to 5 parts of said silicone polyurethane polymer, from 1 to 5 parts of said film-forming ester, and from 1 to 5 parts of said fluorosilicone, on a weight basis.
3. The method according to claim 1 , wherein the weight ratio of silicone polyurethane polymer to film-forming ester to fluorosilicone is about 1:1:1.
4. The method according to claim 1 , wherein the molecular weight of said film-forming ester is greater than about 1000.
5. The method according to claim 4 , wherein said film-forming ester is Triisostearyl Trilinoleate (INCI).
6. The method according to claim 1 , wherein said fluorosilicone has the structure:
where m is an integer from 1 to 5,000,
where n is an integer from 0 to 4,999, and
where x is an integer from 0-to 12.
7. The method according to claim 1 , wherein the fluorosilicone comprises Perfluorononyl Dimethicone (INCI).
8. The method according to claim 1 , wherein the vehicle comprises water and a thickener.
9. The method according to claim 8 , wherein said thickener is a cationic thickener.
10. The method according to claim 9 , wherein said cationic thickener is Polyquaternium-37 (INCI).
11. The method according to claim 1 , wherein said silicone polyurethane polymer, said film-forming ester, and said fluorosilicone, collectively comprise from about 1% to about 20% by weight of the composition.
12. The method according to claim 1 , wherein said silicone polyurethane polymer, said film-forming ester, and said fluorosilicone, collectively comprise from about 1% to about 10% by weight of the composition.
13. The method according to claim 1 , wherein said composition is re-applied to the hair after the first shampooing but prior to a second shampooing.
14. A method for improving color retention of artificially colored hair comprising applying to hair that has been dyed with an oxidative dye, after it has been dyed, a composition comprising:
(i) Bis-Hydroxypropyl Dimethicone/SMDI copolymer;
(ii) Triisotearyl Trilinoleate;
(iii) Perfluorononyl Dimethicone; and
(iv) a vehicle;
wherein at least one of said Bis-Hydroxypropyl Dimethicone/SMDI copolymer, said Triisotearyl Trilinoleate, and said Perfluorononyl Dimethicone are dispersible but not soluble in said vehicle.
15. The method according to claim 14 , wherein each of said Bis-Hydroxypropyl Dimethicone/SMDI copolymer, Triisotearyl Trilinoleate, and Perfluorononyl Dimethicone are dispersible but not soluble in said vehicle.
16. The method according to claim 14 wherein said vehicle comprises water and a cationic thickener.
