Abstract

Abstract A new composition of matter which is an aminofunctional silicone resin. The aminofunctional resin is formed by the reaction of an aminofunctional silane and a silicone resin. A hair treating composition is also disclosed which is a mixture of a film forming material and a solvent for the film forming material. The film forming material is the aminofunctional resin formed by reacting an aminofunctional silane and a silicone resin. A hair treating method for imparting curl retention to hair employing the resin as the film forming material is further described.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 110 words
An aminofunctional silicone resin comprising the reaction product of an aminofunctional silane and a silicone resin having a formula selected from the group consisting of RSiO 3/2 (I) (RSiO 3/2 ) w (R'R''SiO) x (SiO 4/2 ) y (II) (RSiO 3/2 ) w (R'R''SiO) x (SiO 4/2 ) y (R₃'''SiO) z (III) wherein R, R', R'' and R''' are selected from the group consisting of alkyl, alkenyl, aryl and alkylaryl radicals having from one to twenty carbon atoms; and w, x, y and z are integers having a value of from zero to about one thousand with the proviso that the sum of w and y is at least one.
Claim 2
Dependent Claim 29 words
The resin of claim 1 in which the aminofunctional silane is selected from the group consisting of 3-aminopropyltrimethoxysilane, N-(2-aminoethyl)-3-aminopropyltrimethoxysilane, N-(aminoethylaminomethyl) phenyltrimethoxysilane, N-(2-aminoethyl)-3-aminopropyl tris(2-ethylhexoxy)silane, bis(2-hydroxyethyl)-3-aminopropyltrimethoxysilane and 3-(trimethoxysilyl) propyloctadecyldimethyl ammonium chloride.
Claim 3
Dependent Claim 139 words
A hair treating composition comprising a mixture of a film forming material and a solvent for the film forming material, the film forming material being an aminofunctional silicone resin which is the reaction product of an aminofunctional silane and a silicone resin, the silicone resin having a formula selected from the group consisting of RSiO 3/2 (I) (RSiO 3/2 ) w (R'R''SiO) x (SiO 4/2 ) y (II) (RSiO 3/2 ) w (R'R''SiO) x (SiO 4/2 ) y (R₃'''SiO) z (III) wherein R, R', R'' and R''' are selected from the group consisting of alkyl, alkenyl, aryl and alkylaryl radicals having from one to twenty carbon atoms; and w, x, y and z are integers having a value of from zero to about one thousand with the proviso that the sum of w and y is at least one.
Claim 4
Dependent Claim 29 words
The composition of claim 3 in which the aminofunctional silane is selected from the group consisting of 3-aminopropyltrimethoxysilane, N-(2-aminoethyl)-3-aminopropyltrimethoxysilane, N-(aminoethylaminomethyl) phenyltrimethoxysilane, N-(2-aminoethyl)-3-aminopropyl tris(2-ethylhexoxy)silane, bis(2-hydroxyethyl)-3-aminopropyltrimethoxysilane and 3-(trimethoxysilyl) propyloctadecyldimethyl ammonium chloride.
Claim 5
Dependent Claim 144 words
In a hair treating method for imparting curl retention to hair in which a film forming material is applied to hair, the improvement comprising utilizing as the film forming material an aminofunctional silicone resin which is the reaction product of an aminofunctional silane and a silicone resin, the silicone resin having a formula selected from the group consisting of RSiO 3/2 (I) (RSiO 3/2 ) w (R'R''SiO) x (SiO 4/2 ) y (II) (RSiO 3/2 ) w (R'R''SiO) x (SiO 4/2 ) y (R₃'''SiO) z (III) wherein R, R', R'' and R''' are selected from the group consisting of alkyl, alkenyl, aryl and alkylaryl radicals having from one to twenty carbon atoms; and w, x, y and z are integers having a value of from zero to about one thousand with the proviso that the sum of w and y is at least one.
