摘要:
Process for producing microcapsules. Wax or a mixture of wax and protein is dissolved in a mixed solvent consisting of an organic solvent and water, the surfaces of particles of a core substance are wetted with the resulting solution 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 is subjected to a solvent removal treatment.
