摘要： Microcapsules encapsulating acidic materials particularly liquid or solid organic acids, either neat or dispersed in an oil phase, are described. The microcapsules comprise condensation products of alkylated methylol melamine resins in the presence of an acrylic acid-alkyl acrylate co-polymer. An aqueous emulsion is formed with a dispersed organic acid. pH control under acidic conditions along with additions of sulfate salt promotes controlled encapsulation over an extended time period with successive heating to effect condensation and cure.

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.
