The effect of the distribution of polyoxyethylene chain, and the length of alkyl group on the stability of W/O emulsions made by polyoxyethylene type nonionic surfactants, liquid paraffin, and water were investigated. The stability was examined at temperature of 0 to 100°C
The stable W/O emulsions were given by the surfactants having ethyleneoxide distribution without long chain adducts, and having long chain alkyl group. But it is necessary that surfactants are liquid state in emulsion system at store temperature.
