Effects of blending hydrophobic surfactants and polar oils on PIT (Phase Inversion Temperature) and emulsifying power were studied. PIT increased by blending paraffin wax and decreased by blending ester oil and showed a minimum by blending triglycerides. The effect of adding batyl alcohol on PIT was bigger than glyceryl mono stearate in mineral oil and smaller in polar oil. Stearic acid and cetanol gave a little effect on PIT but a large effect on emulsifying power. On containing stearic acid and cetanol fine emulsion was obtained at wider HLB range.
