Described are microcapsule formulations comprising microcapsules having a core of a hydrophobic material, which encloses at least one fragrance or perfume, and a capsule shell which is obtainable by either n i) free-radical polymerization of ethylenically unsaturated monomers comprising: n from 30 to 100% by weight of one or more C 1 -C 24 alkyl esters of acrylic and/or methacrylic acid, n from 0 to 70% by weight of a bi- or polyfunctional monomer, n from 0 to 40% by weight of other monomers; or n ii) acid-induced condensation of melamine-formaldehyde precondensates and/or their C 1 -C 4 alkyl ethers. n Also described are laundry detergent or cleaning product compositions which comprise the microcapsules. |
