Title (EN) MICROCAPSULES CONTAINING A GAS-GENERATING PHOTOLABILE KETOACID OR KETOESTER AND USES THEREOF
(FR) MICROCAPSULES CONTENANT UN ACIDE-CÉTONE OU UN ESTER-CÉTONE PHOTOLABILE GÉNÉRATEUR DE GAZ ET LEURS UTILISATIONS
Abstract: front page image
(EN)The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile α-ketoacid or α-ketoester 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 pouvant se disperser dans l'eau comprenant une phase huileuse, par exemple un parfum, contenant un α-acide-cétone ou un α-ester-cétone photolabile capable de 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 ténacité de la perception olfactive. La présente invention porte également sur l'utilisation desdites microcapsules en parfumerie, ainsi que sur les compositions parfumantes ou les articles parfumés comportant les microcapsules de l'invention en vue d'assurer une libération prolongée de molécules odorantes.
