摘要： Delivery particles encapsulating oily core materials have a shell material of hybrid poly acrylate and poly(beta-amino esters) (PAC/PBAE). The delivery particles may have a single shell of hybrid PAC/PBAE, dual shells including hybrid PAC/PBAE in an inner shell and PBAE in an outer shell crosslinked to the inner shell, or multiple shells including PAC in an inner shell, hybrid PAC/PBAE in a transitioning shell, and PBAE in an outer shell. Formation of the delivery particles includes polymerization between multifunctional amine and multifunctional acrylate to produce a water soluble PBAE; polymerization between the preformed PBAE prepolymer having free methacrylate moieties reactive with a multifunctional (meth)acrylate in the oil phase, or at an interface of the water and oil phases to produce PAC wall, polymerization between polyacrylate and the amine moiety of PBAE prepolymer to produce hybrid PAC/PBAE delivery particle wall; and polymerization between multifunctional acrylate and primary or secondary amine moiety of the PBAE prepolymer to form a PBAE outer shell.

摘要： 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.

摘要： An improved process of making a benefit agent delivery particle and an improved microcapsule made by such process are disclosed. The process comprises the steps of providing a first composition of water phase 1, water phase 2, water phase 3 and an oil phase, where a water phase multifunctional (meth)acrylate monomer is selected to have a hydrophilicity index of least 25, or even at least 30 and the oil phase multifunctional (meth)acrylate monomer has a hydrophilicity index of 25 or less, or even 20 or less. The water phases comprise water, initiator, a water-soluble or dispersible amine(meth)acrylate or hydroxyl(meth)acrylate, a multifunctional (meth)acrylate and one water phase comprises water, carboxyalkyl(meth)acrylate and a base or quaternary ammonium acrylate. Water phases are combined to prereact the hydroxy- or amine(meth)acrylate and the multifunctional (meth)acrylate to form a multifunctional hydroxyl-amine(meth)acrylate pre-polymer. The pre-polymer is combined with the remaining water phase and an emulsion is formed by emulsifying under high shear agitation, an oil phase comprising a multifunctional (meth)acrylate monomer and a benefit agent core material thereby forming a wall surrounding the benefit agent core material.

摘要： An improved process of making a benefit agent delivery particle and an improved microcapsule made by such process are disclosed. The process comprises the steps of providing a first composition of water phase 1, water phase 2 and water phase 3. Water phase 1 comprises water and an initiator; water phase 2 comprises water, a water-soluble or dispersible amine(meth)acrylate or hydroxyl(meth)acrylate and a multifunctional (meth)acrylate. Water phase 3 comprises water, and carboxyalkyl(meth)acrylate and a base or quarternary ammonium acrylate. The first two water phases are combined to prereact the hydroxy- or amine(meth)acrylate and the multifunctional (meth)acrylate to form a multifunctional hydroxyl-amine(meth)acrylate pre-polymer. The pre-polymer is combined with water phase 3; then an emulsion is formed by emulsifying under high shear agitation a second composition into said first composition; said second composition comprising an oil phase comprising an isocyanate and a benefit agent core material thereby forming a wall surrounding the benefit agent core material.

摘要： Novel articles of manufacture are described based on a combination of an adjunct material and microcapsules made by an improved process. The improved microcapsules are chitosan urea and encapsulate a benefit agent. The process comprises combining an adjunct material formed of microcapsules formed by 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.
