Abstract: Populations of benefit agent delivery particles are disclosed, the particles having a core and a shell encapsulating the core, the shell comprising certain multifunctional (meth)acrylate-based polymers, along with processes for making and uses of such compositions. The delivery particle has a core to polymer wall ratio by weight from about 96:4 to about 99.5 to 0.5 and a volume-weighted particle size from about 30 to about 50 microns. The compositions deliver core content with a desired delivery profile, such as fragrance delivery at desired touchpoints with higher efficiency. The delivery particle has high pay load, yet exhibits decreased benefit agent leakage, and provides a desired delivery profile.

Abstract: Microcapsules encapsulating oily core materials have a shell material of hybrid polyurea and poly(beta-amino esters) (PU/PBAE). The microcapsules may have a single shell of hybrid PU/PBAE, dual shells including hybrid PU/PBAE in an inner shell and PBAE in an outer shell crosslinked and deposited to the inner shell, or multiple shells including PU in an inner shell, hybrid PU/PBAE in a transitioning shell, and PBAE in an outer shell. Formation of the microcapsules includes polymerization between multifunctional amine and multifunctional acrylate to produce a water soluble PBAE; polymerization between polyisocyanate in oil phase and multifunctional amine in aqueous solution to produce PU microcapsule, polymerization between polyisocyanate and the amine moiety of PBAE prepolymer to produce hybrid PU/PBAE microcapsule wall; and polymerization between multifunctional acrylate and primary or secondary amine moiety of the PBAE prepolymer to form a PBAE outer shell.

Abstract: An improved process of forming polyurea and chitosan microcapsules encapsulating a benefit agent is described. The process comprises forming a water phase comprising hydrolyzing chitosan in an acidic medium at a pH of 6.5 or less for an extended period and combining with a polyisocyanate. The reaction product of the hydrolyzed chitosan and polyisocyanate yields a microcapsule having improved release characteristics, with enhanced degradation characteristics in OECD test method 301B.
