Abstract: The present invention relates to microcapsules with a core-shell or matrix morphology stabilized by cross-linked nanoparticles. A process for the preparation of said microcapsules comprising selecting internal crosslinking of a Pickering emulsion is also an object of the invention. Perfumed consumer products, in particular fine fragrance, home and personal care products are also part of the invention.

Abstract: Cleavable surfactants of formula (I) having a total hydrophilic-lipophilic balance (HLB) of between 3 and 18 and wherein A is a group capable of releasing a flavor or fragrance aldehyde of formula (R1)CHO or a flavor or fragrance ketone of formula (R1)(R2)CO and is of formula wherein the wavy line indicates the location of the bond between L and A; R1 and R2 represent a hydrogen atom or a saturated or unsaturated C1-C18 hydrocarbon group, provided that at least one of the R1 or R2 groups has 6 consecutive carbon atoms and that both R1 and R2 taken together comprise a maximum of 18 carbon atoms; and L is a linear, branched or cyclic, saturated or unsaturated C3 to C40 hydrocarbon group. These surfactants solubilize and/or stabilize flavor and fragrance aldehydes and ketones in an aqueous environment and at the same time to control their release by hydrolysis.

Abstract: The present invention relates to the field of perfumery. More particularly, it concerns co-polymers, derived from aspartic acid and comprising at least one α- or β-aspartic acid derivative capable of liberating an active molecule such as, for example, an α,β-unsaturated ketone or aldehyde. The present invention concerns also the use of polymers or co-polymers in perfumery as part of a perfuming or malodor counteracting composition, as well as the perfuming compositions or perfumed articles comprising the invention's compounds.
