Studies on the N-lauroyl-N-methylglucamide based microemulsion withε-β fishlike phase diagram

The microemulsion phase behavior of the quaternary system of N-lauroyl-N-methyl-glucamide (MEGA-12)/alcohol/n-octane/water was studied with a ε-β fishlike phase diagram. The composition of the balanced interfacial layer was calculated by the ε-β hydrophile-lipophile balanced (HLB) plane equation. The physicochemical parameters of the system were also obtained. The solubilization power was discussed.
