Abstract:
Hydrogel particles include: a continuous phase of non-crosslinked hydrogel; and a dispersed phase dispersed in the continuous phase. The dispersed phase includes a crystalline organic UV absorber and a solid fat having an organic value (OV) of 310 or more and an inorganic value (IV) of 130 or more on an organic conceptual diagram. The content of the crystalline organic UV absorber in the dispersed phase is 15-70 mass %.
