Abstract: A sunscreen cosmetic achieves high ultraviolet ray protection effect even when restricting a blended amount of the liquid ultraviolet ray absorbing agents ethylhexyl methoxycinnamate and octocrylene, that is stable and has excellent texture, and does not resulting in an unnatural whiteness on application. A sunscreen cosmetic comprises: (A) 0.5 to 10.0 mass % of t-butyl methoxydibenzoylmethane and/or diethylamino hydroxybenzoyl hexyl benzoate; (B) 0.5 to 5.0 mass % of bis-ethylhexyloxyphenol methoxyphenyl triazine; (C) 0.5 to 5.0 mass % of ethylhexyl triazone; (D) 5 to 50 mass % of an ester oil to which the ingredients (A), (B) and (C) have a solubility, at 25° C., of 10% or more; and (E) 1.5 to 12 mass % of an ultraviolet ray scattering agent; wherein the total blended amount of the ingredients (A), (B) and (C) is 1.5 to 15 mass % and the total blended amount of ethylhexyl methoxycinnamate and octocrylene is 3 mass % or less.
