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.
A microcapsule composition comprising microcapsules that contain a microcapsule core and a microcapsule wall encapsulating the microcapsule core, wherein the microcapsule core contains an active material and the microcapsule wall is formed of a covalently bonded polymeric network comprising a polyisocyanate, a whey or plant storage protein, and tannic acid, wherein the tannic acid is connected to the polyisocyanate via a covalent bonding, and wherein the whey or plant storage protein is connected to the polyisocyanate via a covalent bonding.
