Abstract

A skin treatment composition is provided which includes a crosslinked non-emulsifying siloxane elastomer, a skin conditioning agent, a volatile siloxane and no more than 5% water. Hydrocarbons such as petrolatum and polyols such as glycerin are the preferred skin conditioning agents. Inclusion of the elastomer provides a non-traditional smooth/silky feel to the skin upon application with a non-draggy rub in.

Claims

1. A semi-solid skin treatment composition consisting essentially of:

(i) from 0.1 to 30% of a crosslinked non-emulsifying siloxane elastomer formed from a divinyl compound reacted with Si-H linkages of a polysiloxane;

(ii) from 1 to 50% of a skin conditioning agent which is a polyol;

(iii) from 30 to 80% of a volatile siloxane; and

(iv) from 0 to 5% of water.

2. The composition according to claim 1 further comprising a material selected from the group consisting of exfoliants, emollients and mixtures thereof.

3. The composition according to claim 2 wherein the emollient is a hydrocarbon.

4. The composition according to claim 3 wherein the hydrocarbon is petrolatum.

5. The composition according to claim 1 wherein the the polyol is selected from the group consisting of glycerin, propylene glycol, polyethylene glycol and mixtures thereof.

6. The composition according to claim 2 wherein the exfoliant is selected from the group consisting of alpha-hydroxycarboxylic acid, beta-hydroxycarboxylic acid and salts thereof.

7. The composition according to claim 1 wherein water is present from 0 to 3% by weight.
