ABSTRACT:
Silicone-in-water emulsions are prepared wherein the silicone phase as bi-modal and contains at least 25 percent volatile silicone and at least 1 percent high viscosity silicone fluid. The silicone emulsions are particularly useful in skin care compositions. The silicone-in-water emulsions are prepared by a process which is useful to emulsify any high viscosity silicone or mixture of silicones having a viscosity of less than 50 pascal-seconds. The process involves the formation of a rough emulsion followed by the use of low shear, preferably at about room temperature to form a stable emulsion.
