Abstract

A hydroalcoholic cosmetic composition is provided which when topically applied to the face can shrink skin pores. The composition is focused upon denatured ethyl alcohol utilizing menthol as denaturing agent. Further included in the composition are humectants, preservatives and water. Also described is a method for reducing skin pore size.

Claims

1. A hydroalcoholic cosmetic composition comprising:

(i) from about 1 to about 60% denatured ethyl alcohol by weight of the composition and containing from about 0.3 to about 3% menthol by weight of the alcohol;

(ii) from about 0.5 to about 80% humectant by weight of the composition;

(iii) from about 0.00001 to about 3% preservative by weight of the composition; and

(iv) from about 10% to about 85% water by weight of the composition.

2. The composition according to claim 1 wherein the denatured ethyl alcohol is present in an amount from about 5% to about 25% by weight of the composition.

3. The composition according to claim 1 wherein the denatured ethyl alcohol is present in an amount from about 10% to about 40% by weight.

4. The composition according to claim 1 wherein menthol is present from about 1.3 to about 2% by weight of the denatured ethyl alcohol.

5. The composition according to claim 1 further comprising a solubilizer which is a polypropylene glycol copolymer of a C₈-C₂₄ fatty alcohol or acid.

6. The composition according to claim 5 wherein the polypropylene glycol copolymer is PPG-2-lsoceteth-20 Acetate.

7. The composition according to claim 1 which is transparent or translucent.

8. The composition according to claim 7 which is a gel having suspended therein from 1 to 1,000 gas bubbles per cc³, the bubbles having an average diameter ranging from about 0.001 to about 2 mm.

9. The composition according to claim 1 wherein the humectant is selected from the group consisting of glycerol, propylene glycol, dipropylene glycol, polypropylene glycol, polyethylene glycol, sorbitol, hydroxypropyl sorbitol, hexylene glycol, 1,3-butylene glycol, 1,2,6-hexane triol, ethoxylated glycerol, propoxylated glycerol, maltitol, isoprene glycol and mixtures thereof.

10. A method for reducing size of skin pores comprising topically applying to an external surface of a face composition comprising:

(i) from about 1 to about 60% denatured ethyl alcohol by weight of the composition and containing from about 0.3 to about 3% menthol by weight of the alcohol;

(ii) from about 0.5 to about 80% humectant by weight of the composition;

(iii) from about 0.00001 to about 3% preservative by weight of the composition; and

(iv) from about 10% to about 85% water by weight of the composition.
