Abstract

Silicone polyether microemulsions are disclosed containing i) at least 20% by weight of a water immiscible dispersed phase comprising certain polydialkylsiloxane-polyoxyalkylene copolymers having 0.1 to 10 wt % ethylene oxide (C2H4O) groups, optionally a water immiscible silicone or hydrocarbon fluid, and ii) at least 5% by weight of an emulsifier. The silicone polyether microemulsions are optically transparent and have an average particle size of less than 100 nanometers. They may be used in a variety of personal care product formulations. In particular, the silicone polyether microemulsions may be used to prepare “clear” personal care products.
