PRODUCTION METHOD OF HYDROGEL PARTICLE, AND HYDROGEN PARTICLE PRODUCED THEREBY AND DISPERSION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a production method of hydrogel particles which does not necessarily need a cooling facility for cooling droplets.

SOLUTION: The production method of hydrogel particles involves spraying a dispersion obtained by dispersing an oil component in an aqueous water component solution obtained by dissolving a gelling agent of a non-crosslinking type hydrogel having a gelation point of 30°C or higher to gas phase and cooling and solidifying droplets formed thereby.
