ABSTRACT:
An improved skin conditioner, incorporating alpha hydroxy acids, is an emulsion stabilized by the combination of a high molecular weight polyethylene glycol and a quaternary ammonium salt phosphate cationic surfactant, specifically, an alkyl amidopropyl PG-Dimonium Chloride phosphate type cationic surfactant. The composition may include other active agents, non-ionic emulsifying surfactants, emollients and additives. The resulting composition has a desirable "feel" and storage stability, even at relatively high temperatures.
