Abstract
Abstract An endermic liniment comprising a polyoxyethylene dicarboxylate represented by the following chemical formula (1). (In this formula, R1 and R2 are hydrogen or alkyl or branched alkyl groups having 1-4 carbon atoms, and m, n, X, and Y are integers 0-5 which are not all zero at the same time. R3 is a branched or linear chain alkylene group having 0-10 carbon atoms.) The endermic liniment of the present invention achieves superior tactile sensation during use, smoothness in particular, without a sticky sensation, while maintaining a lasting moisture retaining effect by means of blending in a humectant and a polyoxyethylene dicarboxylate.
