Abstract

This invention relates to a process for preparing microcapsules containing a hydrophobic liquid core material, the process comprising: (1) mixing an organic liquid phase which comprises the hydrophobic liquid core material with an aqueous phase comprising a stabilizer to form a premix; (2) homogenizing the premix by forcing the premix under pressure through a high pressure passage into a low pressure area to produce a microparticle dispersion, said microparticles having a mean size of greater than 1.0 micron, (3) adding an encapsulating material prior to step (4); and (4) curing the encapsulating material associated with the microparticles to form the microcapsules.
