Miniemulsions were prepared using mixed emulsifiers comprising of fatty alcohols ROH (C_5OH-C_(16)OH) 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=C_5-C_8) could spontaneously form O/W miniemulsion in kerosene-water system.

Key words: Miniemulsion, Spontaneous emulsification
