The relation between the phase diagrams and the formation of so-called microemulsions (swollen micellar solutions) have been studied. The relation of the amount of oil, water, ionic surfactant, and cosurfactant necessary to obtain transparent one-phase solutions is clearly understood from the phase diagrams. The changes of interfacial tension in hydrocarbon-water systems containing ionic surfactants as a function of added pentanol or octylamine also were studied in connection with phase diagrams. The interfacial tension is very small, and solubilization is maximal when the mixing ratio of ionic (hydrophilic) surfactant and (lipophilic) cosurfactant is optimum. (18 refs.)
