Microcapsule compositions as disclosed comprising a microcapsule dispersed in an aqueous phase. The microcapsule has a microcapsule core and a microcapsule wall encapsulating the microcapsule core. The microcapsule core contains an active material. The microcapsule wall is formed of a polymeric network comprising a first moiety derived from a protein, and a second moiety derived from a multi-functional electrophile. Also disclosed are preparation methods and consumer products containing the microcapsule compositions.
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 polymeric network comprising a polyisocyanate and a cross-linker consisting of (i) whey or a plant storage protein and (ii) tannic acid, wherein the weight ratio of the protein to polyisocyanate is in the range of 1:1 to 10:1, and the microcapsules contain 50% to 90% of the protein by weight of the microcapsule wall.
