Abstract: The present invention relates to a perfume system comprising a core-shell microcapsule A, optionally, a core-shell microcapsule B, and optionally, a free perfume oil, wherein the core of the core-shell microcapsule A and/or the free perfume oil comprises a 2-oxoacetate derivative of formula (I) as well as a perfumed consumer product comprising the same and methods and uses of the same for enhancing, conferring, increasing and/or modifying the fragrance properties and/or the fragrance intensity of perfumed consumer products.

Abstract: Described herein are compounds of formula (I) that are able to provide a long-lasting or substantive odor, in particular floral and/or fruity odor, to the environment. Also described herein is a method of imparting a long-lasting odor, in particular a fresh green, floral and/or fruity odor, to surfaces, such as hard surfaces, fabric, skin or hair. Also described herein are a method of using said compounds in perfumery and perfuming compositions or perfumed articles including the compounds described herein.

Abstract: Described herein are compounds including at least one ?-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an ?,?-unsaturated ketone, aldehyde or nitrile. Also described herein are methods of using said compounds in perfumery as well as perfuming compositions or perfumed articles including the compounds. The compounds are represented by formula (I) where: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous ?,?-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II?) in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II?).

Abstract: Described herein are compounds that are able to generate oct-2-en-4-one and thus to provide a long-lasting or substantive strawberry odor to an environment. Also described herein is a method of imparting a long-lasting strawberry odor to surfaces, such as hard surfaces, fabric, skin or hair. Also described herein is a method of using said compounds in perfumery. Also described herein are perfuming compositions or perfumed articles including the compounds.

Abstract: The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one ?-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an ?,?-unsaturated ketone, aldehyde or nitrile. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. (I) wherein: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous ?,?-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II?) in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II?).

Abstract: 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.

Abstract: The present invention relates to water-dispersable microcapsules comprising an oil phase, e.g. a perfume, containing a photolabile ?-ketoacid or ?-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.

Abstract: A method and apparatus for dispersing a substance, in particular a fragrant or disinfectant substance, into a volume of air comprises a first step of circulating a volume of air inside a conduit and a second step of liberating the substance into the conduit. Circulation of the volume of air ensures ventilation for example of a vehicle, a restaurant, a cinema, or furthermore, a hospital. The substance liberated into the conduit is dispersed in the volume of air by forced convection and leads to a perfumed environment or to air containing an active disinfectant principle. A cylinder is positioned outside the conduit containing the substance to be dispersed and a compressed propellant gas, and the propellant gas is expanded so as to inject the substance into the conduit.
