Abstract: The present invention relates to the field of perfumery. More particularly, it concerns polymers derived from siloxane derivatives and comprising at least one β-thio carbonyl moiety 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 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.

Abstract: The present invention relates to a process for the preparation of organic-inorganic microcapsules, with a flavor or fragrance core and a hybrid shell composed of at least two types of inorganic particles that are cross-linked. Microcapsules obtained by said process are also an object of the invention. Consumer products comprising said capsules, in particular perfumed consumer products in the form of home care or personal care products, are also part of the invention.
