OILY COMPOSITION AND ROD-SHAPED MEDICINAL PREPARATION

摘要

An oily composition which gives a medicinal lip preparation through solidification, characterized by comprising (A) one or more N-acylamino acid derivatives comprising, for example, two dialkylamides of an N-acylglutamic acid, (B) a polyamide resin comprising, for example, a copolymer of the bisdioctadecylamide of dimeric dilinoleic acid and ethylenediamine, and (C) a liquid oil comprising, for example, a dimer acid ester. Upon solidification, the composition gives a medicinal lip preparation which can exhibit sufficient transparency and give a satisfactory use feeling.
