  • POLYMER CONJUGATES FOR A CONTROLLED RELEASE OF ACTIVE MOLECULES
    Publication number: 20100098649
    Abstract: The present invention relates to the field of perfumery. More particularly, it concerns co-polymers, derived from a maleic anhydride derivative and a ethylenic derivative, comprising at least one ?-oxy or ?-thio carbonyl moiety capable of liberating an active molecule such as, for example, an ?,?-unsaturated ketone, aldehyde or carboxylic ester. The present invention concerns also the use of polymers or co-polymers in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds.
    Type: Application

    Inventors: Damien Berthier, Andreas Herrmann
  • Amphiphilic Co-Polymer Conjugates for a Controlled Release of Active Molecules
    Publication number: 20080279799
    Abstract: The present invention relates to the field of perfumery. More particularly, it concerns polyethylene or polypropylene based polymers that have at least one ?-oxy or ?-thio carbonyl moiety capable of liberating a perfuming molecule such as, for example, an ?,?-unsaturated ketone, aldehyde or carboxylic ester. The present invention concerns also the use of such compounds in perfumery as well as the perfuming compositions or perfumed articles that include such compounds.
