    摘要： Core-shell microcapsules comprising a hydrophobic core surrounded by a shell comprising a thermosetting resin comprising moieties derived from polyisocyanates, substantially unprotonated chitosan and another amine different from chitosan, characterized in that the substantially unprotonated chitosan is delivered in the solid, powder form to the locus of the encapsulation reaction. The core-shell microcapsules are provided in the form of a slurry comprising 10 to 50 wt % of microcapsules, based on the total weight of the slurry, and the shell of the microcapsules comprises from 0.1 to 20 wt % of moieties derived from chitosan, based on the total weight of the shell.

    摘要： The invention relates to an encapsulated fragrance composition including at least one microcapsule dispersed in a dispersion medium, said at least one microcapsule including a fragrance oil core and a positively charged shell, which includes a reaction product of at least one at least difunctional anionically modified isocyanate with an amine or alcohol, preferably a polyamine, and wherein the shell is formed around droplet of core material that is stabilized with a positively charged colloidal stabilizer. Furthermore, the invention relates to a process of formation of said encapsulated fragrance compositions.

    摘要： 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.
