摘要： Polyurea capsule compositions. A subset of these compositions contain a plurality of capsules and a capsule formation aid, in which each of the capsules contains a polyurea wall and an oil core; the polyurea wall is formed of a reaction product of a polyisocyanate and a cross-linking agent in the presence of the capsule formation aid; and the oil core contains an active material. The polyisocyante, cross-linking agent, and capsule formation aids are described herein. Also disclosed are methods of preparing polyurea capsule compositions, as well as consumer products containing one of these compositions.

摘要： Disclosed are stable microcapsule compositions each containing a microcapsule dispersed in an aqueous phase and a stabilizing agent. The microcapsule compositions are stable for at least 4 weeks when storing at 45 ° C., and the microcapsule composition is considered stable when (i) the composition has a viscosity of 3000 cP or less and (ii) 20% or less water by volume of the composition is separated from the composition. Also disclosed are consumer products having such a stable microcapsule composition.
