Pseudoternary phase diagrams of microemulsions with ethyl oleate as the oil phase. (A) represents the pseudoternary phase diagrams of microemulsions with Tween®-80 as surfactant (S) and ethanol as cosurfactant (Cos); (B) represents the pseudoternary phase diagrams of microemulsions with Cremophor® EL as surfactant and ethanol as cosurfactant (Cremophor EL/ethanol, S/Cos); (C) represents the pseudoternary phase diagrams of microemulsions with Cremophor EL as surfactant and polyethylene glycol 400 as cosurfactant (Cremophor EL/PEG400, S/Cos); Km represents the weight ratios of surfactant to cosurfactant.
