Abstract
The present invention concerns compositions that comprise alcohol-free microemulsions and methods for their use that include a surfactant, a lipophilic linker, and/or a hydrophilic linker. These compositions can be used, for example, in cosmetic or hair applications. In certain aspects, compositions of the invention have the ability to microemulsify sebum while providing enhanced cleansing of cosmetic products from the skin or hair. In addition, the compositions have the ability to enhance the penetration of skin or hair active ingredients, such as emollients, humectants, anti-oxidants, lipids, vitamins, botanicals, dyes, tanning compounds, etc.
