Patent number: 10646416Abstract: The present invention relates to water-dispersible microcapsules that include 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 such microcapsules in perfumery as well as the perfuming compositions or perfumed articles that include such microcapsules therein to provide a prolonged release of fragrant molecules.Type: GrantFiled: May 21, 2014Date of Patent: May 12, 2020Assignee: Firmenich SAInventors: Andreas Herrmann, Damien Berthier, Nicolas Paret, Alain Trachsel
