A microcapsule preparation is described which contains microcapsules with a core made of a hydrophobic material and a capsule shell made of a polymer which, in copolymerized form, contains at least 1% by weight of cationogenic monomers and / or polyethylenically unsaturated monomers, the unsaturated sites of which are connected via successive chemical bonds , of which at least one bond is acid hydrolyzable. Furthermore, a microcapsule preparation is described, containing microcapsules with a core made of a hydrophobic material, which comprises at least one fragrance or fragrance, and a capsule shell made of a polymer, which in copolymerized form contains at least 1% by weight of anionogenic monoethylenically unsaturated monomers and / or several times contains ethylenically unsaturated monomers, the unsaturated sites of which are connected via successive chemical bonds, at least one bond being hydrolyzable under basic conditions. The microcapsule preparations are used in detergents or cleaning agents. |
