US 2002/0119954 A1 · Composition containing stabilized ascorbic acid, and uses thereof

Abstract

The invention relates to a composition containing ascorbic acid and an oily phase, characterized in that the oily phase contains a partially or totally crosslinked, solid elastomeric organopolysiloxane. The presence of the solid elastomeric organopolysiloxane makes it possible to obtain good stability of the ascorbic acid and thus good efficacy of the composition containing it. The composition can be anhydrous or be in the form of a water-in-oil or oil-in-water emulsion or a triple emulsion. It can be used in particular in the cosmetic and/or dermatological fields. The presence of the solid elastomeric organopolysiloxane also makes it possible to stabilize an emulsion containing ascorbic acid.
