324 JOURNAL OF COSMETIC SCIENCE cations. For high-salinity systems, the amount of co-oil required to form a single-phase microemulsion increases as well as the surfactant concentration. This is an important consideration in the formulation of optimal skin cleansers, as the concentration of salt and the amount of sebum oil produced on human skin, as well as skin temperature, can be highly variable. Thus, a thorough understanding of phase behavior can be used to control the microstructure that forms in situ during skin cleansing. ACKNOWLEDGMENTS This research was supported by Mary Kay, Inc.
