    摘要: Hydrogel particles include a continuous phase portion of non-crosslinked hydrogel and disperse phase portions dispersed in the continuous phase portion. Each of the disperse phase portions contains a solid oil and a liquid oil as an oil component, and titanium oxide particles dispersed therein. The solid oil of the oil component contains a higher alcohol and a solid paraffin, and the content of the solid oil in the disperse phase portion is 1 to 12 mass%. The hydrogel particles have a volume-average particle diameter of 10 to 300 µm.
