  • Publication number: 20130245153
    Abstract: A process of forming microcapsules is described. The microcapsule population is formed by providing an anionic or cationic, solid hydrophilic core material; providing an oil continuous phase, the oil continuous phase comprising one or more esters with chain length up to about 18 carbons. Emulsification is achieved by subjecting the mixture to high shear agitation and heating the mixture for a time sufficient to enable acid or amine acrylate or methacrylate and multifunctional acrylate or methacrylate to form a prepolymer which migrates to the anionic or cationic solid hydrophilic material, thereby forming prepolymers adhered to the hydrophilic core materials. Temperature is held or heating continued for a time sufficient to enable the prepolymer to flow onto and coalesce into a continuous film surface coating on the hydrophilic core material. Heating is carried out or light exposure or both for a time and temperature sufficient to cross link the prepolymers.
