The invention provides protein adhesives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass.

Stable polyurea microcapsule compositions suitable for encapsulating aldehydes with a low viscosity. Also disclosed are consumer products containing such a composition and its preparation methods.

Disclosed are microcapsule compositions each comprising a microcapsule suspended in an aqueous phase and a viscosity control agent, wherein the viscosity control agent is an acrylate copolymer, a cationic acrylamide copolymer, or a polysaccharide. Also disclosed are consumer products containing such a microcapsule composition.

Core shell microcapsules are provided wherein the capsule shell is an interfacial copolymer formed of a gelatin and an isocyanate.
