Improvements in or relating to organic compounds

Abstract

An encapsulated composition comprising at least one core-shell microcapsule is described. The at least one core-shell microcapsule comprises a core containing at least one benefit agent and a shell surrounding the core. The shell comprises a polyurea resin formed by the reaction of at least one trifunctional isocyanate with at least one polyfunctional amine that is not chitosan. The at least one trifunctional isocyanate is an adduct of an aliphatic triol and at least one araliphatic diisocyanate. The weight ratio between the portion of the polyurea resin derived from the trifunctional isocyanate and the core is between 0.09 and 0.30, preferably between 0.10 and 0.20, and more preferably between 0.11 and 0.18. The shell further comprises chitosan. The present disclosure also relates to methods for preparing such encapsulated compositions and their use to enhance the performance of benefit agents in consumer products.
