COMPOSITIONS AND METHODS FOR RESHAPING KERATIN-RICH SUBSTRATES AND FORMING ADHERENT FLEXIBLE FILMS
Compositions and methods for reshaping keratin-rich substrates while forming adherent flexible films contain emulsified or soluble mixtures of silanols and hemiaminals or the reaction products of silanols and hemiaminals including silylated hemiaminals. A method for treating split-ends in hair is also described.
1 . A composition comprising at least one organosilanol component and at least one organic hemiaminal component.
2 . The composition according to claim 1 , wherein the at least one organosilanol is a monomeric, polymeric, or resinous organosilanol.
3 . The composition according to claim 1 , wherein the at least one organosilanol is a hydroxy-terminated polymeric diorganosiloxane.
4 . The composition according to claim 1 , wherein the at least one organosilanol is an organosilanetriol or diorganosilanediol.
5 . The composition according to claim 1 , wherein the at least one organic hemiaminal is selected from the group consisting of a hemiaminal ether, a hemiaminal silyl ether, and a hemiacetal silyl ether.
6 . The composition according to claim 5 , wherein the at least one organic hemiaminal is selected from the group consisting of imidazolidinyl urea, diazolidinyl urea, and polyoxymethylene urea.
7 . The composition according to claim 1 , further comprising an amine bound to a polymeric siloxane.
8 . The composition according to claim 1 , wherein the at least one organosilanol component comprises an organosilanetriol and a diorganosiloxane.
9 . A method for treating split-ends in hair comprising:
(a) applying a substrate-activating composition to the hair;
(b) warming and drying the hair;
(c) applying a fixative composition to the hair; and
(d) warming and drying the hair;
wherein the fixative composition comprises a mixture comprising at least one silanol and at least one siloxane, and at least one organic hemiaminal; and
wherein the substrate-activating component is an aqueous solution having a pH of about 1 to 4 or a pH of about 10 to 13.
10 . The method according to claim 9 , wherein steps (b) and (c) are performed simultaneously.
