The invention provides a cosmetic material with unprecedented and innovative characteristics that the UV protection effect is not reduced by the contact with water such as water or sweat or the heat applied in the use environment. 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). |
