Abstract
Disclosed is a hair conditioning composition comprising a silicone system comprising three types of silicones, and a gel matrix, wherein the silicone system comprising a first silicone having a high viscosity, a second silicone having a low viscosity, and a third silicone which is an aminosilicone, and wherein the composition is prepared by the steps of: the three types of silicones are mixed to form the silicone system; and the silicone system is mixed with the gel matrix. The composition of the present invention can provide improved conditioning benefits such as smooth feel and reduced friction.
Claims1
A hair conditioning composition comprising by weight:
- (a) from about 1% to about 10% of a silicone system comprising:
- (i) a first silicone which is non-volatile, substantially free of amino groups, and has a viscosity of from about 300,000 mm2·s−1 to 700,000 mm2·s−1, wherein the first silicone is polydimethyl siloxane;
- (ii) a second silicone which is non-volatile, substantially free of amino groups, and has a viscosity of from about 30 mm2·s−1 to 100 mm2·s−1, wherein the first silicone is polydimethyl siloxane;
- and
- (iii) a third silicone which is an aminosilicone having a viscosity of from about 3,000 mm2·s−1 to 7,000 mm2·s−1;
- wherein the silicone system forms a silicone pre-mixture;
- (b) a gel matrix comprising:
- (i) from about 1.5% to about 5% of behenyl trimethyl ammonium chloride;
- (ii) from about 2% to about 8% of mixture of stearyl alcohol and cetyl alcohol compound;
- and
- (iii) an aqueous carrier;
- wherein the composition is prepared by a method comprising the steps of:
- (a) mixing the first, second, and third silicones to form the pre-mixture of the silicone system;
- and
- (b) mixing the pre-mixture of the silicone system with the gel matrix.
