    Abstract: Cosmetic products contain a polymer comprising repeat units of formula (I), where R = group of formula (i); R = R , H, alkali metal or ammonium; R = 3-30C alkyl or -CO-R ; R = 3-30C alkyl; X = O or CH2; n = 2-400; and y = 0-6. Also claimed is the preparation of the cosmetic products comprising forming a copolymer from maleic anhydride and an olefin of formula R -X-CH=CH2 (II), reacting the copolymer with a benzophenone derivative of formula (III) and formulating the final copolymer with standard auxiliary agents and additives.

    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.

    Abstract: Use of stabilized ascorbic acid derivatives (I) as antioxidants in cosmetics and pharmaceutical compositions, e.g. shampoos, conditioners, mousses, sun creams and moisturizers is claimed. Some of the ascorbic acid derivatives are new and claimed. The use of ascorbic acid derivatives of formula (I) is claimed in cosmetic and pharmaceutical compositions. R1,R2 = H, 1-20C acyl, 1-12C alkoxycarbonyl or 1-12C alkyl; or R1+R2 = an optionally substituted heterocycle; R3 = H or a cation selected from NH4 or alkali or alkaline earth metal ions; R4 = 1-12C alkoxycarbonyl. Independent claims are also included which cover compounds of formula (Ia) and their preparation. R1', R2' = H or 1-20C acyl; or R1'+R2' = C(Me)2; R4' = 1-6C alkoxycarbonyl.

    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).
