Abstract
A novel monophosphate and a novel diphosphate prepared by a phosphatidyl transfer reaction of a phospholipid and an alcohol in the presence of phospholipase D are disclosed. The phosphates can independently or together form small and stable liposomes which can include active components therein. Cosmetic compositions comprising these phosphates or liposomes penetrate well into the hair and the skin, and exhibit long-lasting excellent moisture-retaining, beauty, skin-activation effects.
