Title (EN) METHOD FOR PROTECTING KERATINOUS MATERIALS AGAINST UV RADIATIONS
(FR) PROCÉDÉ DE PROTECTION DES MATIÈRES KÉRATINIQUES CONTRE LES RAYONNEMENTS UV
Abstract:
(EN) The invention relates to a method for protecting keratinous materials, particularly the skin, against UV radiations comprising applying successively, to the keratinous materials: 1/ a base composition comprising an UV filter, 2/ a finishing composition comprising an UV filter, wherein at least one of the base composition or the finishing composition comprises at least one compound chosen from: - a silicon polymer A having silicon-bonded alkenyl groups called "Si-Alkenyl" groups, - a silicon polymer B having silicon-bonded hydrogens groups called "SiH" groups, - a catalyst C, and mixtures thereof, with the proviso that: - at least one polymer A, one polymer B and one catalyst C are present in either the base or the finishing composition, and that - the polymer A, the polymer B and the catalyst C are not present simultaneously in the same composition, said polymer A and polymer B being capable of reacting together by a hydrosilylation reaction in the presence of said catalyst C when they are contacted with one another, in order to form, on the keratinous material, a continuous protecting film against UV radiations.
(FR) L'invention concerne un procédé de protection de matières kératiniques, en particulier de la peau, contre les rayonnements UV comprenant l'application successive sur les matières kératiniques : 1/ d'une composition de base comprenant un filtre UV, 2/ d'une composition de finition comprenant un filtre UV, la composition de base et/ou la composition de finition comprenant au moins un composé choisi parmi : - un polymère de silicium A ayant des groupes alcényle liés au silicium appelés groupes " Si-alcényle ", - un polymère de silicium B ayant des groupes hydrogène liés au silicium appelés groupes " SiH ", - un catalyseur C, et leurs mélanges, à condition que : au moins un polymère A, un polymère B et un catalyseur C soient présents soit dans la composition de base, soit dans la composition de finition, et que - le polymère A, le polymère B et le catalyseur C ne soient pas présents simultanément dans la même composition, ledit polymère A et le polymère B étant aptes à réagir entre eux par une réaction d'hydrosilylation en présence dudit catalyseur C lorsqu'ils sont mis en contact les uns avec les autres, pour former, sur la matière kératinique, un film de protection continu contre les rayonnements UV.
