Abstract
Oil-in-water emulsions are provided by a process which involves the mixing of the oil and water in the presence of three nonionic surfactants having certain HLB values. The process is particularly useful for emulsifying an oil having a viscosity exceeding 50,000 centipoise (50 pascal-seconds). Any oil can be emulsified by this process, including hydrocarbon oils like mineral oil and petrolatum, and silicones, including fluids, gums and resins. A particularly useful emulsion prepared by this process is an emulsion of a bi-modal silicone which contains substantial amounts of a volatile silicone and a silicone gum.
