摘要

BI-MODAL SILICONE EMULSIONS, SILICONEEMULSIFICATION PROCESS AND EMULSIONS THEREFROMABSTRACTSilicone-in-water emulsions are prepared whereinthe silicone phase is bi-modal and contains at least 25percent volatile silicone and at least 1 percent highviscosity silicone fluid. The silicone emulsions areparticularly useful in skin care compositions. Thesilicone-in-water emulsions are prepared by a process whichis useful to emulsify any high viscosity silicone or mixtureof silicones having a viscosity of less than 50 pascal-seconds. The process involves the formation of a roughemulsion followed by the use of low shear, preferably atabout room temperature to form a stable emulsion.
