Improvements in or relating to organic compounds

An encapsulated composition comprising at least one core-shell microcapsule is disclosed. 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 thermoset 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 group and the quaternary ammonium group to the carboxylic acid group is from 0.9 to 1.1, preferably from 0.95 to 1.08, more preferably from 1.00 to 1.06. 公开了一种包封的组合物，其包含至少一种芯-壳微胶囊。所述至少一种芯-壳微胶囊包含芯和围绕所述芯的壳，所述芯含有至少一种香料成分。所述壳包含通过包含至少一个氨基基团的多官能胺与至少一种多官能异氰酸酯的反应形成的热固性树脂。所述壳进一步包含含有季铵基团的阳离子聚合物。所述壳进一步包含含有完全或部分解离的羧酸基团的聚合物稳定剂。所述氨基基团和所述季铵基团与所述羧酸基团的标称摩尔比为0.9至1.1，优选0.95至1.08，更优选1.00至1.06。
