The present invention provides a substance that has low irritation to the skin and promotes transdermal absorption of pharmacologically active ingredients. At least one selected from the group consisting of isopulegol, 2- (menthoxy) ethanol, and 2-methyl-3- (menthoxy) propane-1,2-diol is blended as a transdermal absorption enhancer. Furthermore, it is possible to obtain an external preparation for skin with improved transdermal absorbability, preferably by blending pharmacologically active ingredients such as psychotropic ingredients, anti-inflammatory ingredients, analgesic ingredients, antipyretic ingredients, whitening ingredients, and hair growth ingredients.
