Abstract
Resin particles are produced by adding a liquid material having a boiling point of 100° C. or higher to an aqueous dispersion of resin particles to yield a mixture, recovering a wet cake from the mixture by filtration, and drying the wet cake. A water-soluble material is preferably used as the liquid material. The liquid material may also be at least one compound selected from compounds listed in The Japanese Standards of Cosmetic Ingredients, The Japanese Cosmetic Ingredients Codex, The Pharmacopoeia of Japan, and The Japan's Specifications and Standards for Food Additives. According to this method, there are provided resin particles which are resistant to coagulation upon drying and are satisfactorily dispersible in other materials.
