Abstract

Clear emulsion cosmetic compositions are provided that include an aqueous phase having 2-methyl-1,3-propanediol and an oily phase containing silicones, especially cyclomethicone and a cyclomethicone-dimethicone copolyol silicone fluid mixture. These compositions exhibit visual clarity and can be formulated into a cold cream or antiperspirant/deodorant which are highly phase stable and insensitive to shear decomposition while being processed.

Claims

1. A clear emulsion cosmetic composition having an optical clarity of better than 50 NTU at 21°

C. comprising;

(i) from 10 to 97% by weight of an aqueous phase comprising 2-methyl-1,3-propanediol; and

(ii) from 2 to 90% by weight of an oily phase comprising a silicone oil.

2. The composition according to claim 1 wherein the silicone oil comprises from 1 to 50% by weight of the cosmetic composition of a cyclomethicone-dimethicone copolyol silicone fluid mixture having a viscosity at 25°

C. of 100 to 1,000 cst, and from 1 to 50% by weight of the cosmetic composition of cyclomethicone.

3. The composition according to claim 2 further comprising from 0.5 to 10% by weight of the cosmetic composition of a blend of cyclomethicone and dimethiconol.

4. The composition according to claim 1 further comprising from 1 to 50% by weight of the cosmetic composition of a poly (C₂ -C₄ alkoxylate) polymer.

5. The composition according to claim 1 wherein the 2-methyl-1,3-propanediol is present in an amount from 1 to 70%.

6. The composition according to claim 1 wherein the 2-methyl-1,3-propanediol is present in an amount from 10 to 50%.
