Abstract

Methods and compositions for whitening or brightening skin comprising at least one whitening active contained in association structures.

Claims

1. A topical composition for whitening skin comprising at least one whitening active contained in association structures.

2. The composition of claim 1 wherein the association structures are liposomes, vesicles, liquid crystals, micelles, reverse micelles or combinations thereof.

3. The composition of claim 2 wherein the association structures are vesicles.

4. The composition of claim 3 wherein the association structures are unilamellar vesicles and wherein the whitening agent is a diphenyl methane.

5. The composition of claim 3 wherein the association structures are multilamellar vesicles and wherein the whitening agent is a botanical extract.

6. The composition of claim 1 wherein the association structures are formed from polar lipids in aqueous media.

7. The composition of claim 4 in the form of a serum or gel.

8. An aqueous emulsion topical composition comprising at least one whitening active contained in association structures, an aqueous phase and an oil phase.

9. The composition of claim 8 wherein the aqueous phase contains at least one aqueous phase structuring agent and the oil phase contains at least one oil phase structuring agent.

10. The composition of claim 8 wherein the whitening active contained in association structures is in the aqueous phase of the emulsion.

11. The composition of claim 9 wherein the aqueous phase structuring agent is polysaccharide, acrylate copolymer, a high molecule weight PEG or polyglycerin, or mixtures thereof.

12. The composition of claim 9 wherein the oil phase structuring agent is a silicone elastomer, a silicone gum, a silicone wax, a polyamide, a natural or synthetic wax, a montmorillonite mineral, or mixtures thereof.

13. The composition of claim 8 wherein the composition is a skin cream or lotion and is in the form of an emulsion comprising at least one volatile silicone, at least one oil phase structuring agent, at least one aqueous phase structuring agent, and at least one nonionic surfactant.

14. A method for whitening skin comprising applying to skin desired to be whitened a topical composition comprising at least one composition containing a whitening active in association structures.

15. A method for treating skin for improvement comprising applying to skin in need thereof a topical composition comprising at least one whitening active contained in association structures and at least one sunscreen.
