<P>PROBLEM TO BE SOLVED: To produce hydrogel particles in which a fatty acid divalent metal salt is finely dispersed in a particle. <P>SOLUTION: The method for production of hydrogel particles includes: a sol preparation process of dissolving a gel forming agent of a non-crosslinked type hydrogel in water and preparing a sol in which at least one powder hardly soluble in water selected from the group consisting of fatty acid divalent metal salt, fatty acid acyllysine and fatty acid acyltaurine divalent metal salt is dispersed; and a gel particle-forming process of gelating the sol prepared by the above process by forming the droplet of the sol and cooling. In the sol preparation process, the gel forming agent is dissolved after dispersing in water, the powder hardly soluble in water, or the dispersion liquid dispersing the powder in water and a sol solution dissolving the gel-forming agent in water are mixed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
