Alkane and /alpha/-olefin sulfonates can be utilized to produce optimal microemulsion formulations which have very high salinity (including divalent ion) tolerance while maintaining large solubilization parameters and low interfacial tensions. Such molecules require elevated temperatures or higher alcohol concentrations to suppress liquid crystal formulation. As found for other species, solubilization is inversely related to width of the three phase regime, and interfacial tension and solubilization are strongly coupled. 18 refs.
