Abstract: Described are encapsulated compositions comprising at least one core-shell microcapsule. The at least one core-shell microcapsule comprises a core comprising at least one benefit agent and a shell surrounding the core. The shell comprises a polyurea resin formed by reaction of at least one trifunctional isocyanate with at least one polyfunctional amine not being chitosan. The at least one trifunctional isocyanate is an adduct of an aliphatic triol with at least one araliphatic diisocyanate. The weight ratio between moieties of the polyurea resin, which are derived from the trifunctional isocyanate, and the core is between 0.09 and 0.30, preferably between 0.10 and 0.20, more preferably between 0.11 and 0.18. The shell additionally comprises chitosan. The present disclosure also relates to a method for preparing such encapsulated compositions and to their use to enhance the performance of a benefit agent in a consumer product.

Abstract: 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: a) Providing an aqueous phase (I) comprising at least one anionically modified polyisocyanate (A); b) Providing an organic phase (II) comprising at least one fragrance ingredient; c) Mixing the aqueous phase (I) and the an organic phase (II) to obtain a mixture; d) Forming an emulsion comprising droplets of the organic phase (II) in the continuous aqueous phase (I); e) Adding at least one polyfunctional amine; f) Effecting formation of shells around the droplets formed in step d), to obtain a dispersion of microcapsules. The process comprises the additional step of adding a polyisocyanate (B), which is different from polyisocyanate (A).
