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 elastomer, comprising the cross-linked hydrosilylation reaction product of:

(i) an alkenyl functional silicone compound;

(ii) a silylhydride functional silicone compound; and
