A core-shell microcapsule comprising a core containing a functional ingredient and a shell surrounding or at least partially surrounding said core, the shell comprising a thermosetting resin formed by the reaction of shell-forming monomers comprising a polyamine and a material comprising a plurality of olefinic double bonds capable of reacting with the polyamine.

Core-shell microcapsule with a polyamine-based thermosetting shell

An encapsulated perfume composition comprising a slurry of core-shell microcapsules in a suspending medium, the core comprising at least one perfume ingredient, and the shell comprising a thermosetting resin formed by the reaction of shell-forming materials selected from monomers, pre-polymers and/or pre-condensates, and wherein the encapsulated perfume composition comprises a polymeric stabilizer that is a reaction product of a polymeric surfactant, and a silane that contains functional groups capable of forming covalent bonds with the shell.

Encapsulated perfume compositions and methods of preparing them

Disclosed is a process for preparing an encapsulated fragrance composition. The composition comprises a plurality of microcapsules dispersed in a dispersion medium. The microcapsules comprise a core and a shell around the core. The process comprises the consecutive steps of: The process comprises the additional step of adding a polyisocyanate (B), which is different from polyisocyanate (A).
