摘要： This disclosure relates to a biodegradable core-shell microcapsule that includes (a) a shell containing the reaction product of an isocyanate-functionalized prepolymer with a crosslinker and optionally a polyelectrolyte under an aqueous condition, and (b) a core containing an active material, wherein the isocyanate-functionalized prepolymer is the reaction product of a polyisocyanate with a biopolymer and/or an amphiphilic compound under an anhydrous condition, and the microcapsule shell is substantially free of or free of a self-condensed polyisocyanate. This disclosure also relates to a process of preparing such biodegradable core-shell microcapsule. This disclosure also relates to a consumer product containing such biodegradable core-shell microcapsule. This disclosure also relates to a process of making the isocyanate-functionalized prepolymer.
