A sunscreen or daily care composition comprising
- (i) hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate) in an amount of from 1% to 9% by weight based on the total weight of the composition;
- and
- (ii) 1-(4-(1,1-dimethylethyl)phenyl)-3-(4-methoxyphenyl)propane-1,3-dione (INCI butyl methoxydibenzoylmethane);
- and
- (iii) at least one organic particulate UV filter;
- and
- (iv) at least one emollient with a polarity index of <30 mN/m,
- wherein the composition does not comprise 2-hydroxy-4-methoxybenzophenone (INCI oxybenzone), ethylhexyl-2-cyano-3,3-diphenyl-acrylate (INCI octocrylene) and benzylidene malonates according to the following preferred structures:
- wherein
- R1 is methyl, ethyl, propyl or n-butyl;
- if R1 is methyl, then
- R is tert. butyl or a radical of formula
- or a radical of formula
- wherein
- R2 and R3 are independently from each other hydrogen or methyl;
- R4 is methyl, ethyl or n-propyl;
- R5 and R6 are independently from each other hydrogen or C1-C3-alkyl;
- if R1 is ethyl, propyl or n-butyl, then
- R is isopropyl.
Use of hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate) and at least one organic particulate UV filter for photostabilizing 1-(4-(1,1-dimethylethyl)phenyl)-3-(4-methoxyphenyl)propane-1,3-dione (INCI butyl methoxydibenzoylmethane) in a sunscreen or daily care composition, wherein the composition does not comprise 2-hydroxy-4-methoxybenzophenone (INCI oxybenzone) and ethylhexyl-2-cyano-3,3-diphenyl-acrylate (INCI octocrylene).
