    Abstract: The present invention relates to sunscreen or daily care composition comprising (i) hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate); and (ii) 1-(4-(1,1-dimethylethyl)phenyl)-3-(4-methoxyphenyl)propane-1,3-dione (INCI butyl methoxydibenzoylmethane); and (iii) 2,4-bis-{[4-(2-ethy-hexyoxy)-2-hydroxy]-pheny}-6-(4-methoxypheny)-1,3,5 triazine (INCI bis-ethylhexyloxyphenol methoxyphenyl triazine); and (iv) 4,4′,4″-(1,3,5-triazine-2,4,6-triyltriimino)tris-benzoic acid-tris(2-ethylhexyl)ester (INCI ethylhexyl triazone) and/or 4, 4′-[[6-[[4-[[(1,1-dimethylethyl)amino]carbonyl]phenyl]amino]-1,3,5-triazin-2,4-diyl]diimino]bis-benzoic acid-bis(2-ethylhexyl)ester (INCI diethyl-hexyl-butamidotriazone); and (v) at least one organic particulate UV filter, wherein the composition is free of ethylhexyl-2-cyano-3, 3-diphenyl-acrylate (INCI octocrylene), 2-ethylhexyl-(2E)-3-(4-methoxyphenyl) acrylate (INCI ethylhexyl methoxy cinnamate) and pp benzylidene malonates, and wherein the composition comprises diethylamino hydroxybenzoyl hexylbenzoate and butyl methoxydibenzoylmethane in a ratio of larger or equal to 0.8. Furthermore, the present invention relates to the use of said composition for the administration to sensitive skin. In addition, the present invention relates to the use of said composition to reduce sand adhesion after application of the composition on the skin.
