  • Polysiloxane conjugates as fragrance delivery systems
    Patent number: 9765282
    Abstract: The present invention relates to the field of perfumery. More particularly, it concerns polymers derived from siloxane derivatives and comprising at least one ?-thio carbonyl moiety capable of liberating an active molecule such as, for example, an ?,?-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.
