Abstract: Disclosed are microcapsule compositions having a microcapsule that contains a microcapsule core and a microcapsule shell encapsulating the microcapsule core. The microcapsule has a particle size of 1 micron to 100 microns in diameter. The microcapsule core contains an active material. The microcapsule shell is formed of at least three moieties, in which a first moiety is derived from a polygalactomannan, a second moiety is derived from a polyisocyanate, and a third moiety is derived from a multi-functional aldehyde or a tannic acid.

Abstract: Disclosed are microcapsule compositions comprising a microcapsule dispersed in an aqueous phase. The microcapsule has a microcapsule core and a microcapsule wall. The microcapsule core contains an active material. The microcapsule wall encapsulates the microcapsule core and is formed of a polymeric network having a protein moiety, a multi-functional electrophile moiety, and a third moiety derived from a chaotropic agent, a multi-functional nucleophile, or a combination thereof. Also disclosed are preparation method and consumer products containing the microcapsule composition.
