Abstract

A hair care composition which comprises (a) one or more polymer systems in the form of discrete particles, wherein said particles are swollen with a non-aqueous solvent; and (b) water or a hydroalcoholic solution carrier, are described. A method for treating hair which comprises contacting said hair with compositions of the invention is also described.

Claims

1. A hair care composition which comprises

(a) one or more polymer systems in the form of discrete particles, wherein said particles are swollen with a non-aqueous solvent and

(b) water or a hydroalcoholic solution carrier;

wherein the one or more polymer systems is a polymonomethyl siloxane derived from R₁SiO_1.5 units wherein R is selected from the group consisting of alkyl, alkenyl, aralkyl and aryl.

2. A hair care composition which comprises

(a) one or more polymer systems in the form of discrete particles wherein said particles are swollen with a non-aqueous solvent, and

(b) water or a hydroalcoholic solution carrier;

wherein said one or more polymer systems is a mixture of polydimethyl siloxanes and polymonomethyl siloxanes; and

wherein the polydimethyl siloxanes are derived from R₃SiO_0.5 units and R₂SiO units; and

the polymonomethyl silaxanes are derived from R₁SiO_1.5 wherein each R is independently selected from the group consisting of alkyl, alkenyl, aralkyl, and aryl.
