  • Patent number: 5605694
    Abstract: The invention relates to a stabilized, cosmetically and/or dermatologically acceptable emulsion intended to moisturize the skin. This emulsion contains a fatty phase, an aqueous phase, at least one emulsifying agent and at least one moisturizing agent. The aqueous phase contains at least one phosphated compound capable of releasing, via an enzymatic reaction when it is in contact with the skin, an active agent other than the moisturizing agent, which promotes moisturization of the skin, and the fatty phase contains at least one silicone-containing gum and/or one perfluoro oil. The emulsion according to the invention makes it possible to combat ageing of the skin, acne, pigmentation of the skin and/or hair loss.
