Beschreibung
Zusammenfassung:	Disclosed is an encapsulated composition comprising at least one core-shell microcapsule. The at least one core-shell microcapsule comprises a core containing at least one perfume ingredient and a shell surrounding the core. The shell comprises a thermosetting resin formed by reaction of a polyfunctional amine comprising at least one amino group with at least one polyfunctional isocyanate. The shell further comprises a cationic polymer comprising quaternary ammonium groups. The shell further comprises a polymeric stabilizer comprising fully or partially dissociated carboxylic acid groups. The nominal molar ratio of the amino groups and the quaternary ammonium groups to the carboxylic acid groups is from 0.9 to 1.1, preferably from 0.95 to 1.08, more preferably from 1.00 to 1.06. L'invention concerne une composition encapsulée comprenant au moins une microcapsule à noyau et enveloppe. La ou les microcapsules à noyau et enveloppe comprennent un noyau contenant au moins un ingrédient de parfum et une enveloppe entourant le noyau. L'enveloppe comprend une résine thermodurcissable formée par réaction d'une amine polyfonctionnelle comprenant au moins un groupe amino avec au moins un isocyanate polyfonctionnel. L'enveloppe comprend en outre un polymère cationique comprenant des groupes ammonium quaternaire. L'enveloppe comprend en outre un stabilisant polymère comprenant des groupes acide carboxylique totalement ou partiellement dissociés. Le rapport molaire nominal des groupes amino et des groupes ammonium quaternaire aux groupes acide carboxylique est de 0,9 à 1,1, de préférence de 0,95 à 1,08, de préférence encore de 1,00 à 1,06.
