摘要： The present invention relates to the field of perfumery. More particularly, it relates to compounds of formula (I) that are able to provide a long-lasting or substantive odor to the environment. Moreover, the present invention relates to a method of imparting a long-lasting odor to environment or to surfaces, such as hard surfaces, fabric, skin or hair. Furthermore, the present invention relates to the use of said compounds in perfumery, as well as the perfuming compositions or perfumed articles comprising the invention’s compounds.

摘要： The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile polymer comprising α-ketoacid or α-ketoester group 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 perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant molecules.
