A microcapsule system having an outer microcapsule with an outer capsule shell is disclosed. The outer microcapsule comprises at least one inner microcapsule with an inner capsule shell and a first fragrance composition. The inner microcapsule comprises a second fragrance composition that differs from the first fragrance composition. Methods for the production of such micr, products that contain said microcapsules, methods for producing polysensory olfactory impressions and to the corresponding use of the microcapsule system.

Microcapsule system for polysensory olfactory effects I

The present invention provides a microcapsule comprising a shell and a core. The core comprises at least one active ingredient and at least one surface-modified disintegrant.

Thermally opening stable core/shell microcapsules

The invention relates to microcapsules, the capsule walls of which comprise a resin that can be obtained by reacting a) at least one compound selected from the group consisting of a1) amines and a2) aromatic or heteroaromatic compounds which are unsubstituted or substituted with one or more substituents from the group consisting of C-C-alkyl, OH, OR, COOH, SH, SR, NHCOR, OCOR, halogen, or an aromatic compound, where R is a C-C-alkyl group, with b) at least one aldehydic component that contains at least two carbons atoms per molecule, in the presence of c) at least one copolymer which contains units of 2-acrylamido-2-methylpropane sulphonic acid or salts (AMPS) thereof and/or 2-acrylamido-2-methylpropane phosphonic acid or salts (AMPP) thereof and units of one or more (meth)acrylates.
