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： The invention describes a method of forming a stable aqueous polyurethane microgel dispersion comprising preparing an oil phase comprising a gel-forming polyol and an isocyanate in approximately stoichiometric proportion by blending the polyol and isocyanate for a time, less than the gel time of the polyol and isocyanate, thereby forming a homogeneous flowable liquid mixture; providing a water phase comprising a surfactant dispersed in water; combining the water phase with the oil phase flowable liquid mixture and subjecting the combined water and oil phases to high shear agitation to form an aqueous emulsion of micro-size droplets of the oil phase flowable mixture in water; and agitating the emulsion for a time sufficient for the micro-size droplets to polymerize, forming a stable aqueous suspension of solid polyurethane micro-size gel particles. The resultant aqueous suspension of solid polyurethane micro-sized gel particles is substantially free of isocyanate monomer, and is a shelf-stable aqueous suspension of solid polyurethane micro-size gel particles in water. Optionally, a benefit agent is incorporated during or after formation of the microgel dispersion.

摘要： The invention discloses a microencapsulated phase change material having a specific Thermal Efficiency Index (TEI). The composition of the invention comprises particles of a microencapsulated phase change material, the particles comprising a core and a shell that encapsulates the core, the shell comprising a polyurea obtained by polymerizing an isocyanate and an amine, prepared by (i) providing a water phase with an emulsifier, (ii) providing an internal phase of a core material and a multifunctional isocyanate soluble or dispersible in the internal phase, (iii) adding the internal phase to the water phase under high speed agitation to form an emulsion comprising droplets of the internal phase dispersed in the water phase and forming a first shell at an interface of the internal phase droplets and water phase mixture, and (iv) adding a multifunctional amine monomer to the emulsion thereby forming additional polyurea shell over the first shell at an interface of the internal phase droplets and water phase mixture. The resulting particles have a Thermal Efficiency Index greater than 0. Microcapsules according to the invention are highly effective at delivering enhanced thermal performance as compared to conventional microcapsules.
