The invention provides a cosmetic material with unprecedented and innovative characteristics that the UV protection effect is not reduced by contact with water such as water or sweat or heat applied in the use environment, but the effect is improved. The present invention relates to a cosmetic comprising (A) an ultraviolet protective agent, (B) one or more selected from (i) alkylene oxide derivatives and (ii) polyhydric alcohols which are water-soluble and have an IOB of 5.0 or less, And (C) oil phase tackifier, the mass ratio of (A) component/(B) component is 20 or less, and the above (B)(i) alkylene oxide derivative is a polymer represented by the following formula (I) Oxyalkylene-polyoxyethylene copolymer dialkyl ether: R 1 O-[(AO) m (EO) n ]-R 2 (I) (wherein R 1 and R 2 each independently represent a carbon atom Hydrocarbon groups of 1 to 4 or hydrogen atoms, AO represents an oxyalkylene group having 3 to 4 carbon atoms, EO represents an oxyalkylene group, and 1≦m≦70, 1≦n≦70, and m+n≦40).本發明提供一種具有藉由與水或汗等水分之接觸或於使用環境下所施加之熱，紫外線防護效果不但未降低，反而效果提昇之前所未有之革新特性的化妝料。本發明係關於一種化妝料，其包含(A)紫外線防護劑、(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、及(C)油相增黏劑，(A)成分/(B)成分之質量比為20以下，且上述(B)(i)環氧烷衍生物為下述式(I)所表示之聚氧伸烷基-聚氧乙烯共聚物二烷基醚：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，且1≦m≦70、1≦n≦70、且m＋n≦40)。
