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.

Efficient sunscreen compositions with diethylamino hydroxybenzoyl hexyl benzoate and butyl methoxydibenzoylmethane free of octocrylene

The present invention relates to sunscreen or daily care compositions comprising butyl methoxydibenzoylmethane, at least one UV filter selected from triazine derivatives, at least one photostabilizer selected from butyl octyl salicylate, benzotriazolyl dodecyl p cresol, ethyl hexyl methoxycrylene, polyester-8, diethyl hexyl syringylidenemalonate, trimethoxybenzylidene pentanedione, diethylhexyl 2,6-naphthalate, a fused ring cyanoacrylate derivative and polyester-25, wherein the composition does not comprise octocrylene and ethyl hexyl methoxy cinnamate.

Sunscreen compositions comprising butyl methoxydibenzoylmethane, triazine derivatives and photostabilizer

The present invention relates to sunscreen or daily care compositions comprising hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate), 1-(4-(1,1-dimethylethyl)phenyl)-3-(4-methoxyphenyl)propane-1,3-dione (INCI butyl methoxydibenzoylmethane) and at least one organic particulate UV filter, wherein the composition does not comprise 2-hydroxy-4-methoxybenzophenone (INCI oxybenzone) and ethylhexyl-2-cyano-3,3-diphenyl-acrylate (INCI octocrylene).

Efficient sunscreen compositions with diethylamino hydroxybenzoyl hexyl benzoate, butyl methoxydibenzoylmethane and organic particulate UV filter

The present invention relates to the use of methylene bis-benzotriazolyl tetramethylbutylphenol, optionally in combination with tris-biphenyl triazine, to reduce fabric staining of a sunscreen or daily care composition, wherein the sunscreen or daily care composition comprises (i) at least one particulate UV-f liter; and/or (ii) at least one oil soluble UV-A filter, wherein the at least one oil soluble UV-A filter is present in an amount of at most 3% by weight, based on the total weight of the sunscreen or daily care composition; and/or (iii) at least one water soluble UV filter. Furthermore, the present invention relates to the use of methylene bis-benzotriazolyl tetramethylbutylphenol, optionally in combination with tris-biphenyl triazine, to facilitate the washability of such sunscreen or daily care compositions from textiles.
