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 personal care composition, said composition comprising a silicone elastomer, said silicone 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 personal care composition of claim 1, wherein the composition is in the form of water-in-oil emulsion, an oil-in water emulsion or an anhydrous emulsion.

3. The personal care composition of claim 1, further comprising one or more components selected from emollients, pigments, vitamins, sunscreen compounds and sunblock compounds.

4. An antiperspirant composition comprising one or more active antiperspirant agents and a silicone elastomer, said silicone 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.
