Microcapsules, encapsulation method therefor, and method of use thereof.

摘要

A encapsulation method applicable to pharmaceutical preparations, cosmetics, pigment imparting materials such as inks, paints, dyes, electrostatic toner, and others with the use of auxiliary materials such as emulsifiers or surfactants dispensed with the method includes the steps of preparing an organic phase consisting of a mixture of one or more hydrophobic liquid and/or solid materials (1) and self dispersable resin (2) which through the action of an aqueous phase, self disperses into particles with a diameter of 0.1 mu m and less ; combining an aqueous phase with the organic phase, whereby self emulsification takes place, thereby encapsulating the one or more hydrophobic liquid and/or solid materials.
