Abstract

An emulsion cosmetic composition comprising at least one resveratrol derivative, an aqueous phase, and an oil phase, having at least one silicone surfactant, and a method for preparing emulsions capable of delivering active resveratrol to the skin.

Claims

1. An emulsion cosmetic composition comprising at least one resveratrol derivative, an aqueous phase, an oil phase, and at least one silicone surfactant.

2. The composition of claim 1 wherein the resveratrol derivative is dispersed or solubilized in the aqueous phase of the emulsion.

3. The composition of claim 1 wherein the resveratrol derivative is dispersed or solubilized in the oil phase of the emulsion.

4. The composition of claim 1 wherein the silicone surfactant comprises at least one of dimethicone copolyols, alkyl dimethicone copolyols, and emulsifying silicone elastomers.

5. The composition of claim 4 wherein the silicone surfactant is a dimethicone copolyol.

6. The composition of claim 4 wherein the silicone surfactant is an alkyl dimethicone copolyol.

7. The composition of claim 4 wherein the silicone surfactant is an emulsifying silicone elastomer.

8. The composition of claim 1 wherein the resveratrol derivative is a resveratrol ester of an inorganic acid.

9. The composition of claim 1 wherein the resveratrol derivative is an ester of a C_1-40 carboxylic acid.

10. The composition of claim 1 wherein the silicone surfactant has the formula:

wherein p and q are from 0 to 40, wherein PE is (—

C₂H₄O)_a—

(—

C₃H₆O)_b—

H, wherein a is from 0 to 25, b is from 0 to 25, with the proviso that a and b cannot both be 0 simultaneously, and wherein x, y and z are each independently ranging from 0 to 1 million, with the proviso that they cannot all be 0 simultaneously.

11. The composition of claim 1 wherein the composition is a skin cream or lotion and comprises a mixture of volatile and nonvolatile silicones, at least one ester oil, and at least one humectant, and wherein the silicone surfactant is dimethicone copolyol.

12. The composition of claim 1 wherein the composition is a skin cream or lotion and comprises at least one volatile silicone, at least one oil phase structuring agent, at least one aqueous phase structuring agent, and wherein the silicone surfactant is a fatty alkyl dimethicone copolyol.

13. The composition of claim 1 wherein the composition is a foundation makeup composition wherein the oil phase comprises a mixture of volatile and nonvolatile silicones, at least one humectant, and particulates, and wherein the silicone surfactant is an emulsifying silicone elastomer.

14. The composition of claim 13 wherein the particulates comprise a mixture of pigments and powders.

15. The composition of claim 1 which is a mascara.

16. The composition of claim 15 further comprising an oil phase structuring agent, which is a polyamide.

17. The composition of claim 1 which is a skin cream, lotion, or makeup, further comprising a chemical sunscreen.

18. The composition of claim 17 wherein the chemical sunscreen is a UVA sunscreen.

19. The composition of claim 1 wherein the silicone surfactant is selected from the group consisting of dimethicone copolyol;

cetyl dimethicone copolyol;

lauryl dimethicone copolyol;

PEG-11 methyl ether dimethicone;

PEG/PPG-20/22 butyl ether dimethicone;

lauryl dimethicone/polyglycerin-3 crosspolymer; and

mixtures thereof.

20. A method for preparing a stable emulsion capable of delivering active resveratrol to the skin comprising incorporating into the emulsion a resveratrol derivative and a silicone surfactant, wherein one or more of the hydroxyl groups of the resveratrol derivative are protected.
