The present invention provides an oily cosmetic with an unprecedented and innovative characteristic that the ultraviolet protection effect is not reduced by the heat applied in the use environment, but the effect is improved. The present invention relates to an oily cosmetic comprising (A) an ultraviolet protective agent, and (B) one selected from (i) alkylene oxide derivatives and (ii) polyhydric alcohols which are water-soluble and have an IOB of 5.0 or less the above, The above (B) (i) alkylene oxide derivatives are the following formula (I): R 1 O-[(AO) m (EO) n ] -R 2 (I) (In the formula, R 1 and R 2 independently represent a hydrocarbon group having 1 to 4 carbon atoms or a hydrogen atom, AO represents an oxyalkylene group having 3 to 4 carbon atoms, EO represents an oxyethyl group, 1 ≦ m ≦ 70, 1 ≦ n ≦ 70, and m + n ≦ 40) The represented polyoxyalkylene · polyoxyethylene copolymer dialkyl ether, and the water content in the oily cosmetic is 5 mass% or less.本發明提供一種具有紫外線防禦效果不因於使用環境下施加之熱而降低，反而效果提昇之前所未有之革新特性的油性化妝料。本發明係關於一種油性化妝料，其包含(A)紫外線防禦劑、及(B)選自水溶性且IOB為5.0以下之(i)環氧烷衍生物及(ii)多元醇中之1種以上，上述(B)(i)環氧烷衍生物係下述式(I)：R1O-[(AO)m(EO)n]-R2(I)(式中，R1及R2分別獨立地表示碳原子數1～4之烴基或氫原子，AO表示碳原子數3～4之氧伸烷基，EO表示氧伸乙基，1≦m≦70，1≦n≦70，且m+n≦40)所表示之聚氧伸烷基·聚氧乙烯共聚物二烷基醚，且該油性化妝料中水之含量為5質量%以下。
