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.一種聚合物膠束載體組成物，其包含：i)嵌段共聚物，其具有親水性聚合物鏈片段及疏水性聚合物鏈片段；ii)帶電界面活性劑；及iii)脂肪油。該載體組成物可應用作為化妝品組成物或醫藥品組成物之基材，且非親油性藥物之載持性優異。非親油性藥物可舉毛成長促進胜肽為例。
