    Abstract: New polymer (I) comprises at least two polyorganosiloxane blocks, at least one of which has at least two hydrogen-bonding groups and at least one of which has at least one solar filter or antiradical group, is new. (I) is soluble in a silicone oil at 25-250degreesC and is capable of gelling the silicone oil. New polymer (I) comprises at least two motifs, each containing at least one polyorganosiloxane radical comprising 1-1000 siloxane units in the main chain or as a graft, where: (a) at least one motif comprises at least two hydrogen-bonding groups selected from ester, amide, sulfonamide, carbamate, thiocarbamate, urea, thiourea, oxamido, guanidino and biguanidino groups, provided that at least two groups are not ester groups; and (b) at least one motif comprises at least one group capable of acting as a solar filter or antiradical agent covalently bonded in the polymer chain and/or laterally and/or terminally; provided that the hydrogen bonding groups are not exclusively oxamido groups when the solar filter group is an oxamide group. (I) is soluble in a silicone oil at 25-250degreesC and is capable of gelling the silicone oil. Independent claims are also included for: (1) cosmetic or dermatological composition comprising an oil phase containing a silicone oil gelled with (I); (2) cosmetic treatment to protect the skin and natural or sensitized hair against UV radiation by applying a cosmetic composition containing (I); (3) protecting a cosmetic composition containing a light-sensitive ingredient against UV radiation by incorporating 0.25-3 wt.% (I) into the composition.

    Abstract: Silylated p-phenylenediamine or p-aminophenol derivatives (I) are new. Compounds of formula (I) and their salts are new: A = OH or NH2; R1, R2 = H, 1-8C alkyl, 1-6C hydroxyalkyl or YB, or NR1R2 is a 4- to 7-membered heterocycle optionally substituted with 1-3C alkyl, OH, NH2 or ZB; R3, R4 = H, 1-4C alkyl, 1-4C alkoxy, halo or ZB; Y = a 1-8C (un)saturated hydrocarbon chain optionally interrupted with O, S or NR; Z = Y, OY or (NR)Y; R = H or 1-4C alkyl; B = SiR5R6R7; R5-R7 = 1-4C alkyl or phenyl; provided that R1 and R2 are H when A is OH and that at least one of R1-R4 is YB or ZB. Independent claims are also included for: (1) an oxidation dye composition comprising a developer of formula (I); (2) a method for dyeing keratinic fibers, comprising applying the composition of (1) and developing the color with an oxidizing agent; (3) a kit comprising a compartment containing the composition of (1) and a compartment containing an oxidizing composition; (4) a colored product produced by oxidizing the composition of (1).

    Abstract: New insoluble aryl vinylene ketone type UV radiation filtering compounds of two specified formulae are presented in the form of particles with average size 10 nm to 5 micro m, and used to protect a material sensitive to UV radiation, in particular solar radiation or to prepare medicaments designed to prevent the adverse effect of UV radiation. New insoluble aryl vinylene ketone type UV radiation filtering compounds are of formula (I) or (II), and are presented in the form of particles with average size 10 nm to 5 micro m. n = 1, 2; A in (I) and (II), when n is 1 = formulae (a)-(d); A in (I), when n is 2 = formulae (e)-(h); R4 = OH, halogen, 1-6C alkyl or alkoxy optionally containing a silicon atom, 1-5C alkoxycarbonyl, 1-6C alkylsulfonamide optionally containing a silicon atom, aminoacid; R1 = H, OH; R2 = H, 1-6C alkyl optionally containing a silicon atom, cyano, 1-6C alkylsulfonyl, phenylsulfonyl; R3 = 1-6C alkyl optionally containing a silicon atom, phenyl capable of forming a bicycle and optionally substituted by one or two R4, with R2 a 2-10C mono- bi- or tricyclic hydrocarbon residue optionally interrupted by one or more nitrogen or oxygen or sulfur atoms and capable of containing another carbonyl and optionally substituted with a 1-8C alkylsulfonamide optionally containing a silicon atom or an aminoacid; p = 0-4; q = 0, 1; when n is 1 R2 and R3 do not form a camphor nucleus. Independent claims are included for a non-therapeutic method of protecting the skin or hair against UV radiation by applying the claimed composition or a claimed compound and for a non-therapeutic procedure for controlling variation in the color of the skin caused by UV radiation by applying the claimed composition or a claimed compound.
