even when the skin is wet, to provide a cosmetic oil composition can be readily familiar for makeup dirt is washed away and refreshing leaves no oily feel by washing with water. Cosmetic oil composition of the present invention of the formula (1) R 1 O- (C 3 H 6 O 2) n 1 -H (1) (Wherein represents an average degree of polymerization of glycerin, R 1 is 1.0 to 4.5 .n 1 is a hydrocarbon group having 12 to 22 carbon atoms which may have a hydroxyl group) formulas 1 to 30% by weight of polyglycerol monoalkyl ether represented by the formula (2) R 2 O- (C 3 H 6 O 2) n 2 -H (2) (Wherein represents an average degree of polymerization of glycerin, R 2 is 5 to 20 .n 2 is a hydrocarbon group having 8 to 22 carbon atoms which may have a hydroxyl group) 1 to 30% by weight of polyglycerol monoalkyl ether represented by the formula, containing 40 to 98% by weight of the oil at least one component selected from silicone oils, ester oils, and triacylglycerols.皮膚が濡れた状態でも、メイク汚れに対し容易になじみ、水洗により油性感を残さずさっぱりと洗い流すことができる化粧料用油組成物を提供する。本発明の化粧料用油組成物は、式(1)R1O-(C3H6O2)n1-H (1)(式中、R1はヒドロキシル基を有していてもよい炭素数12~22の炭化水素基を示す。n1はグリセリンの平均重合度を示し、1.0~4.5である)で表されるポリグリセリンモノアルキルエーテルを1~30重量%、式(2)R2O-(C3H6O2)n2-H (2)(式中、R2はヒドロキシル基を有していてもよい炭素数8~22の炭化水素基を示す。n2はグリセリンの平均重合度を示し、5~20である)で表されるポリグリセリンモノアルキルエーテルを1~30重量%、シリコーン油、エステル油、トリグリセロールから選ばれる少なくとも1種類の油性成分を40~98重量%含有する。
