Abstract
Abstract A hair treating method for imparting curl retention to hair in which at least one film forming ingredient is applied to the hair. The improvement utilizes as the film forming ingredient an organosilicon compound which is a hydrocarbon solvent free water soluble pre-hydrolyzed organofunctional silane having silsesquioxane characteristic. Hair care and fixative compositions including the silane are also disclosed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
210 words
A method of making a prehydrolyzed silsesquioxane having the formula: (Z--Y--X--R--SiO.sub.3/2).sub.n wherein X is a radical selected from the group consisting of amino, ammonium, quaternary amino, carbonyl, sulfonyl, and amido, or an oxygen atom; Y is an oxygen atom, a radical selected from the group consisting of alkylene, arylene, alkylarylene, aryleneoxy, alkylaryleneoxy, carbonyl, and phosphoryl, or a covalent bond; Z is hydrogen or a radical selected from the group consisting of alkyl, alkenyl, aryl, amino, amido, ammonium, hydroxy, carboxy, vinyl, vinylbenzene, epoxy, vinylbenzylamino, alkylacrylo, metal hydroxyl, alkylcarbonyl, arylcarbonyl, morphilino, and oxazolino; R is a radical selected from the group consisting of alkylene, arylene, alkylarylene, and alkenylene, or an oxygenated, aminated, amidated, or thiolated substitution thereof; and n is an integer having a value of from one to ten thousand, comprising (i) adding a silane to an alcohol in a vessel; (ii) mixing the silane and the alcohol; (iii) adding water to the silane and alcohol; (iv) mixing the silane, alcohol, and water; (v) isolating a solid silsesquioxane product by heating the vessel to evaporate the alcohol and water; (vi) cooling the vessel and removing the solid silsesquioxane product from the vessel; the silane being a compound selected from the group consisting of ethylenediaminopropyltrimethoxysilane; propyltrimethoxysilane; 3-(trimethoxsilyl)-propyldimethylammonium chloride; sodium-3-trihydroxysilylpropylmethyl phosphonate; and aminopropyltrimethoxysilane.
Claim 2
Independent Claim
210 words
A method of making a prehydrolyzed silsesquioxane having the formula: (Z--Y--X--R--SiO.sub.3/2).sub.n wherein X is a radical selected from the group consisting of amino, ammonium, quaternary amino, carbonyl, sulfonyl, and amido, or an oxygen atom; Y is an oxygen atom, a radical selected from the group consisting of alkylene, arylene, alkylarylene, aryleneoxy, alkylaryleneoxy, carbonyl, and phosphoryl, or a covalent bond; Z is hydrogen or a radical selected from the group consisting of alkyl, alkenyl, aryl, amino, amido, ammonium, hydroxy, carboxy, vinyl, vinylbenzene, epoxy, vinylbenzylamino, alkylacrylo, metal hydroxyl, alkylcarbonyl, arylcarbonyl, morphilino, and oxazolino; R is a radical selected from the group consisting of alkylene, arylene, alkylarylene, and alkenylene, or an oxygenated, aminated, amidated, or thiolated substitution thereof; and n is an integer having a value of from one to ten thousand, comprising (i) adding a silane to an alcohol in a vessel; (ii) mixing the silane and the alcohol; (iii) adding water to the silane and alcohol; (iv) mixing the silane, alcohol, and water; (v) isolating a solid silsesquioxane product by heating the vessel to evaporate the alcohol and water; (vi) cooling the vessel and removing the solid silsesquioxane product from the vessel; the silane being a compound selected from the group consisting of ethylenediaminopropyltrimethoxysilane; propyltrimethoxysilane; 3-(trimethoxsilyl)-propyldimethylammonium chloride; sodium-3-trihydroxysilylpropylmethyl phosphonate; and aminopropyltrimethoxysilane.
Claim 3
Dependent Claim
23 words
The method of claim 1 in which the alcohol is a compound selected from the group consisting of ethanol, isopropanol, n-octanol, and n-decanol.
Claim 4
Dependent Claim
29 words
The method of claim 1 in which the silsesquioxane has the formula (NH 2 CH 2 CH 2 NHCH 2 CH 2 CH 2 SiO 3/2 ) n .
Claim 5
Dependent Claim
37 words
A method of providing curl retention to hair comprising flaking the solid silsesquioxane produced by the method of claim 1; dissolving the flaked solid silsesquioxane in water to form a solution; and applying the solution to hair.
Claim 6
Dependent Claim
38 words
A method of providing curl retention to hair comprising flaking the solid silsesquioxane produced by the method of claim 1; dissolving the flaked solid silsesquioxane in an alcohol to form a solution; and applying the solution to hair.
Claim 7
Dependent Claim
24 words
A method according to claim 5 in which the alcohol is a compound selected from the group consisting of ethanol, isopropanol, n-octanol, and n-decanol.
