ABSTRACT:
A unique method for the preparation of oil-in-water microemulsions is described. In carrying out this method, microemulsions are prepared in a four-step process: (1) a surfactant is selected which is just barely soluble in the oil phase; (2) the surfactant thus selected is dissolved in the oil to be emulsified in an amount effective to yield a fine emulsion of the emulsified oil in an aqueous phase; and (3) the oil, together with its dissolved surfactant, is added to the water phase and shaken or stirred; and (4) finally, there is provided a second surfactant in the water phase which is somewhat more soluble in water than the first surfactant to produce a substantially clear microemulsion of oil in water.
