Application of W/O Emulsions to Cosmetic Foundations

摘要

W/O emulsions are suitable for cosmetic foundations, as they are excellent in water repellency. In particular when silicone oils are used for the oil a felling of W/O emulsions is good. In order to obtain the structure condition as W/O type surfactants to prepare stable W/O silicone emulsions, glycerylether derivatives with silicone chains were focused on. And stable low-viscosity W/O emulsions were prepared by using the most suitable glycerylether modified silicone. In this paper the stabilization mechanism and the application example for cosmetic foundations are described.
