Title (EN) MICROCAPSULES CONTAINING A GAS-RELEASING PHOTOLABILE COMPOUND AND USES THEREOF
(FR) MICROCAPSULES CONTENANT UN COMPOSE PHOTOLABILE DE LIBÉRATION DE GAZ, ET LEURS UTILISATIONS
Abstract: front page image
(EN)The present invention relates to water-dispersible microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile compound capable of generating a gas upon exposure to light. The gas is able to cause an extension or the breaking of the microcapsule allowing the release of the oil phase and thus increasing the long-lastingness of the odor perception. The present invention concerns also the use of said microcapsules in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.
(FR)La présente invention concerne des microcapsules dispersables dans l'eau, comprenant une phase huileuse, par exemple un parfum, contenant un composé photolabile apte à générer un gaz lors d'une exposition à la lumière. Le gaz peut entraîner une extension ou la rupture de la microcapsule permettant la libération de la phase huileuse et augmentant ainsi la durée de la perception d'odeur. La présente invention porte également sur l'utilisation desdites microcapsules en parfumerie, ainsi que sur les compositions de parfum ou les articles parfumés comportant les microcapsules de l'invention pour assurer une libération prolongée de molécules parfumées.
