Abstract

The cross-linked hydrosilylation reaction product of an alkenyl functional silicone compound, a silylhydride functional silicone compound, and one or more allyl started, hydrogen, alkyl, aryl or acyl terminated polyether compounds exhibits stability, compatibility with polar organic solvents and is useful as a component in personal care compositions.

Claims

1. A silicone composition, comprising:

a liquid medium, said liquid medium comprising an organic liquid; and

a silicone elastomer dispersed in the liquid medium, said elastomer comprising the cross-linked hydrosilylation reaction product of (i) an alkenyl functional silicone compound;

(ii) a silylhydride functional silicone compound; and

(iii) one or more allyl started, hydrogen, alkyl, aryl or acyl terminated polyether compounds.

2. The silicone composition of claim 1, wherein the composition is subjected to shear force to break the silicone elastomer into particles.

3. The silicone composition of claim 1, wherein the composition comprises, based on 100 parts by weight of the composition, from 1 part by weight to 99 parts by weight of the liquid medium, from 1 part by weight to 99 parts by weight of the silicone elastomer.

4. The silicone composition of claim 1, wherein the liquid medium comprises an organic liquid and a silicone fluid that is miscible with the organic liquid.
