Combinations of photoprotective triazine derivatives (I) and polysiloxane UV filters (II) are new. Preferably (II) are of formula (IIa) or (IIb), where R, R" = 1-10C alkyl or phenyl; X, X' = 1-10C alkyl, phenyl or Y; r = 0-100; s = 0-20, at least one of X and X' being Y when s = 0; t = 0-10; v = 1-10, provided that v+t = 3 or more; Y = a UV absorbing chromophore, preferably of formula (III) or (IV); R1 and R2 = 1-10C alkyl; R3-R5 = H or 1-10C alkyl; p = 1-10; and Q', Q" = H, OH, 1-10C alkyl or 1-10C alkoxy. |
