摘要： A method for producing a nonaqueous composition for external use on the skin including a strongly hydrophilic amphiphilic solid active ingredient-surfactant complex dissolved or dispersed in an oil phase, the method including the steps of: dissolving a surfactant in an oil phase to obtain a surfactant solution; mixing the obtained surfactant solution with a strongly hydrophilic amphiphilic solid active ingredient to obtain a suspension; and allowing the obtained suspension to stand still to obtain a transparent composition. Unlike conventional methods for preparing S/O formulations, the strongly hydrophilic amphiphilic solid active ingredient can be solubilized in an oil phase without the process of emulsification and freeze drying.
