Benefits of technology

The invention is a cosmetic product made up of a mixture of resveratrol and other ingredients. It has a smooth texture and is easy to apply. The product also has a suitable viscosity for storage in standard cosmetic containers. The oil phase structuring agent helps give the product a pleasant feel when applied.

Problems solved by technology

However, one problem with resveratrol is that it is generally unstable in cosmetic formulations.
Accordingly, if used in cosmetic formulas, it can only be used in very small amounts.
If present in too large an amount, the resveratrol will hydrolyze and cause the cosmetic formulation into which it is incorporated to become discolored.

Abstract

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

Description

[0001]This application claims priority from U.S. provisional patent application Ser. No. 60 / 952,874, filed Jul. 31, 2007.TECHNICAL FIELD[0002]The invention is in the field of emulsion cosmetic compositions for application to keratinous surfaces.BACKGROUND OF THE INVENTION[0003]Resveratrol, also referred to as 3,5,4′-trihydroxystilbene, is a polyhydroxy-substituted compound having the general formula:[0004]It is present in red grapes, raspberries, blueberries, and certain other plant berries or extracts. It has been reported that resveratrol has anti-aging, anti-cancer, and antiviral effects. Because of its perceived fountain-of-youth properties, resveratrol has been incorporated into a variety of cosmetic formulations, such as skin creams. However, one problem with resveratrol is that it is generally unstable in cosmetic formulations. Accordingly, if used in cosmetic formulas, it can only be used in very small amounts. If present in too large an amount, the resveratrol will hydrolyz...
