MICROCAPSULES AND PROCESS FOR PRODUCING THEM

摘要

This process for producing microcapsules includes dissolving wax or a mixture of wax and protein in a mixed solvent consisting of an organic solvent and water, wetting, with the resulting solution, the surfaces of particles of a core substance at temperatures of 45 deg.C or below to selectively deposit the wax or the mixture of wax and protein on the particle surfaces and allow them to coat the particle surfaces. And then a slurry containing the particles are subjected to a solvent removal treatment.
