  • Patent number: 9422505
    Abstract: The present invention relates to a carrier system for fragrances, to the production thereof and to the use of the carrier system in laundry and cosmetic formulations. Accordingly, the present invention is directed to a microcapsule comprising a core of hydrophobic material composed of at least one fragrance or perfume and a microcapsule shell obtainable by the suspension polymerization of the following monomers: (a) one or more C1-C24-alkyl ester(s) of (meth)acrylic acid (monomer A), (b) one or more bi- or polyfunctional monomers (monomer B) and (c) optionally, one or more other ethylenically unsaturated monomers (monomer C), wherein the shear rate for the preparation of the emulsion lies in the range of from 150 to 500 rpm and the stirring time for the preparation of the emulsion lies in the range of from 15 min to 180 min.
    Type: Grant

  • Publication number: 20130295154
    Abstract: The present invention relates to a microcapsule comprising a capsule core, which contains a pheromone, and a capsule wall, which contains in polymerized form 30 to 90% by weight of one or more C1-C24-alkyl esters of acrylic acid and/or methacrylic acid, acrylic acid, methacrylic acid and/or maleic acid (monomers I), 10 to 70% by weight of one or more difunctional and/or poly-functional monomers (monomers II), and 0 to 40% by weight of one or more other monomers (monomer III), in each case based on the total weight of the monomers. The invention further relates to a process for the preparation of said microcapsules; a method for controlling undesired insect infestation; and a composition for controlling undesired insect infestation comprising a pheromone and ethyl 3-methylbutanoate.
