POLYMER MICELLE CARRIER COMPOSITION AND MEDICINE-CONTAINING POLYMER MICELLE COMPOSITION

摘要

Provided are a polymer micelle carrier composition and a medicine-containing polymer micelle composition that enable improvement of efficiency of penetration of a medicine to the skin. This polymer micelle carrier composition includes: an aqueous medium; and a block copolymer that forms a polymer micelle structure in the aqueous medium and that has a hydrophilic polymer chain segment and a hydrophobic polymer chain segment. The polymer micelle carrier composition further contains a penetration accelerator at concentration a such that the contact angle ratio calculated according to formula A is less than or equal to 0.82.
