an oil - in - water emulsion is prepared with certain siloxane - oxyalkylene copolymeric surfactants which have in the emulsion a combined hlb value of between about 4 - 7 . the oil phase includes silicone oils which are volatile and silicone oils or gums which are non - volatile , or mixtures of silicone oils and gums . what is unexpected and unusual about the invention is that conventional wisdom dictates that surfactant packages having a combined hlb value of 4 - 7 result in water - in - oil emulsions rather than oil - in - water emulsions .
