POLYMERIC MICELLE CARRIER COMPOSITION AND POLYMERIC MICELLE COMPOSITION

摘要

A polymeric micelle carrier composition comprising (i) a block copolymer having a hydrophilic polymer chain segment and a hydrophobic polymer chain segment, (ii) a charged surfactant and (iii) a fat or oil. The carrier composition can be used as a base material for a cosmetic composition or a pharmaceutical composition, and has excellent properties of carrying a non-lipophilic drug. One example of the non-lipophilic drug is a hair growth-promoting peptide.
