Miniemulsions were prepared using mixed emulsifiers comprising of fatty alcohols ROH (C5OH-C16OH) and ionic or noinonic surfactants in low concentration.As a cosurfactant, fatty alcohol served as an aid for decreasing the interfacial tension and increasing the lifetime of oil drops at the oil-water interface. The mixed emulsi fier R(EO)12-NP(EO)2-ROH(R=C5-C8) could spontaneously form O/W miniemulsion in kerosene-water system.
