  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.

  本发明涉及水分散微胶囊，包括油相，例如香水，其中含有能够在光照作用下产生气体的光敏化合物。该气体能够引起微胶囊的延展或破裂，从而释放油相，从而增加气味感知的持久性。本发明还涉及在香水中使用所述微胶囊，以及包含本发明微胶囊的香水组合物或香水制品，以提供芳香分子的持续释放。
