    Abstract: A photostable ultraviolet (UV) filter for protecting human skin or hair against sunlight contains as UV-A absorbing components a combination of a hydroxybenzophenone (I), optionally together with a 4,4-diaryl-butadiene (II); and other UV protectant(s) i.e. dibenzoylmethane, triazine, benzotriazole, benzimidazole, tetrahydroxybenzophenone and/or organosiloxane-benzal malonate derivatives. Use of a light-protectant combination of a UV-A absorber and further UV-A and/or UV-B absorbers is claimed as a photostable UV-filter in cosmetic or pharmaceutical preparations for protecting human skin or hair against sunlight, optionally used together with other conventional light protectants. First UV light absorber is a hydroxybenzophenone of formula (I), optionally together with a 4,4-diaryl-butadiene of formula (II); and other UV protectants including 4-(R6)-4'-(R7)-dibenzoylmethane, 1,3,5-triazine derivatives of formula (III), 2,4,6-triphenyl-1,3,5-triazines, in which the phenyl rings are bonded with at least one o-hydroxy group and at least one p-(1-20C) alkoxy group, 2,2'-dihydroxy-3,3'-bis-(1,2,3-benzotriazol-2-yl)-5,5'-bis-(1,1,3,3-te tramethylbutyl)-diphenylmethane, 1,4-bis-(5,6-disulfo-benzimidazol-2-yl)-benzene or its salts, 2-(2-hydroxy-3-(2-methyl-4,4-bis-(trimethylsilyloxy)-4-silapentyl)-5-m ethyl)-1,2,3-benzotriazole, 2,2',4,4'-tetrahydroxybenzophenone and/or siloxanes of formula (IV). R1, R2 = H, 1-20C alkyl, 3-10C cycloalkyl or 3-10C cycloalkenyl; or NR1R2 = 5-6 membered ring; R3 = 1-20C alkyl; R4, R5 = H, 1-20C alkyl, 3-10C cycloalkyl or 3-10C cycloalkenyl; R6 = 1-12C alkyl; R7 = H, 1-12C alkyl or 1-12C alkoxy; R8-R10 = optionally substituted 1-20C alkyl, 5-10C aryl, 5-10C heteroaryl or -Sp-Sil; Sp = spacer; Sil = silane, oligosilane or polysiloxane residue; X = O or NR11; R11 = H or optionally substituted 1-20C alkyl, 5-10C aryl, 5-10C heteroaryl; V = 3-(4-(2,2-bis-(ethoxycarbonyl)-vinyl)-phenoxy)-prop-1-en-1-yl or 3-(4-(2,2-bis-(ethoxycarbonyl)-vinyl)-phenoxy)-prop-1-en-2-yl; V' = V or Me; t = up to 100; u = up to 20; provided that u = 0 if V' = V or u = 1-20 if V' = Me. An Independent claim is also included for cosmetic or pharmaceutical preparations for protecting human epidermis or hair against UV light in the 280-400 nm range, comprising the UV absorbing combination, a carrier and optionally other conventional light protectants.

    Abstract: Use of new and known bicyclic and tricyclic enamines as UV filters in cosmetic and pharmaceutical preparations is new. Also new is their use for the protection of plastics. Use of bicyclic and tricyclic enamines as UV filters in cosmetic and pharmaceutical preparations is new. R and R = CN; alkylcarbonyl; alkoxycarbonyl; aryloxycarbonyl; or optionally substituted aminocarbonyl; R = H; 1-20C alkyl; 3-20C cycloalkyl; or -CH2-CH2-SO3 M ; M = cation; X = -O-; -S-; or -N(R )-; Z' = group of formula (ii) or (iii): R = H; alkyl, cycloalkyl, alkoxy, cycloalkoxy, alkoxycarbonyl, alkyl-NH-CO-, (alkyl)2-NH-CO-, alkyl-NH- or (alkyl)2N- (each with up to 20C); CN; NH2; or SO3 M and more than 1 R can be present. Independent claims are also included for: (1) the use of compounds (I) as light screening agents for the protection of plastics; (2) (I; Z' = (iii); and (3) (I; Z' = (ii); R4 = R40; R1, R2 = R10, R20 respectively) R and R = CN or 2-10C alkoxycarbonyl optionally substituted with -(CH2)n-SO3 M ; R = H; CH3; or -(CH2)n-SO3 M ; R = H; 1-8C alkyl; 1-8C alkoxy; or -SO3 M ; n = 2 or 3; M = H or HN(R )(R )(R ) ; R -R = H lower alkyl optionally substituted with OH; or a metal cation; but at least one -(CH2)n-SO3 M or -SO3 M must be present.
