Patent ID: 8343466

Claim:
Hydrogel particles, comprising: a continuous phase portion of non-crosslinked hydrogel; and at least one disperse phase portion dispersed in said continuous phase portion; wherein each of said at least one disperse phase portion comprises a solid oil and a liquid oil as an oil component, and titanium oxide particles dispersed therein; said solid oil of said oil component comprises behenyl alcohol and a solid paraffin, and the concentration of said solid oil in said oil component is 4 to 12 mass %; the concentration of behenyl alcohol in said oil component is 2 to 6 mass %; the total concentration of solid paraffin in said oil component is 2 to 6 mass %; the concentration of said titanium oxide particles in said disperse phase portion is 5 to 50 mass %; the total concentration of solid oil in said disperse phase portion is 1 to 12 mass %; the total concentration of liquid oil in said disperse phase portion is 50 to 80 mass %; and said hydrogel particles have a volume-average particle diameter of 10 to 300 μm.
