Title
(EN) CATALYTIC SYSTEMS, METHODS, AND ARTICLES FOR DELIVERY OF OXYGEN TO SKIN
(FR) SYSTÈMES CATALYTIQUES, MÉTHODES ET ARTICLES POUR L'ADMINISTRATION D'OXYGÈNE À LA PEAU
Abstract
(EN)
A system for providing a cosmetic article that can deliver oxygen and skin brightening includes a first composition that includes at least one oxidizer; and a second composition that includes a peroxide decomposing catalyst wherein contacting each of the first and second compositions together results in oxygen generation. The system can include in the first composition at least one cross-linkable polymer and in the second composition at least one alkaline booster and at least one catalyst whereby contacting the first and second compositions on a substrate, such as skin, results in cross-linking the cross-linkable polymer to form a continuous film and simultaneous release of oxygen that is contained between the substrate and the film.
(FR)
Un système pour fournir un article cosmétique qui peut apporter de l'oxygène et un éclaircissement de la peau comprend une première composition qui comprend au moins un oxydant ; et une seconde composition qui comprend un catalyseur de décomposition de peroxyde, le contact de chacune des première et deuxième compositions ensemble entraînant la génération d'oxygène. Le système peut comprendre dans la première composition au moins un polymère réticulable et dans la seconde composition au moins un renforçateur alcalin et au moins un catalyseur, ainsi la mise en contact des première et seconde compositions sur un substrat, tel que la peau, conduit à réticuler le polymère réticulable pour former un film continu et libérer simultanément de l'oxygène qui est contenu entre le substrat et le film.
