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. 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. 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. |
