Effects of blending homogeneous octaoxyethylene-monododecyl ether and pure lipophilic surfactants on cloud point (Cp), PIT and emulsifying properties have been studied.
Cp is proportional to HLB value of mixture. The efficiency of PIT reduction is different with respect to structure of lipophilic surfactant, and the lower HLB lipophilic surfactans have smaller efficiency of PIT reduction. PIT is linearly decreased with increasing the fraction of MGS in mixture, and efficiency of PIT reduction is larger at high fraction of BL-3 SY in mixture. BL-2SY and DGS have better O/W emulsifying properties. (BL-nSY: homogeneous POE dodecylether, MGS: glyceryl mono-stearate, DGS: glyceryl di-stearate)
