    Abstract: Photo-stable ultraviolet (UV) filters for cosmetic or pharmaceutical use consist of substituted alpha -methyl-styrene derivatives (I). The use of substituted alpha -methyl-styrene derivatives of formula (I), optionally in combination with conventional UV absorbers, as photo-stable UV filters in cosmetic or pharmaceutical preparations for protecting human skin or hair against sunlight is new. R1 = 4-10C alkoxy, 1-12C alkylamino, 1-12C dialkylamino (sic) or a water-solublizing group selected from carboxylate, sulfonate and ammonium residues; R2 = H, 2-10C alkyl or 1-12C alkoxy; R3,R4 = COOR5, COR5, CONR5R6 or CN, R4 and R5 being the same; R5,R6 = H, 1-12C alkyl, 2-10C alkenyl, 3-10C cycloalkyl, 3-10C cycloalkenyl, aryl or heteroaryl (optionally substituted). Independent claims are given for: (1) the use of (I) as photostable UV-A filters; (2) the use of (I) as UV stabilizers; (3) cosmetic and pharmaceutical compositions for protecting human epidermis or skin against UV light in the 280-400 nm region, comprising a carrier containing (I) (as photostable UV filter) and optionally conventional UV absorbers; (4) (I) for use as medicaments; and (5) pharmaceutical preparations containing (I).
