PROBLEM TO BE SOLVED: To provide a hydrogel particle that keeps high protection effect even after friction.SOLUTION: A hydrogel particle comprises a continuous phase comprising non-crosslinked hydrogel, and a dispersion phase dispersed in the continuous phase. The dispersion phase comprises solid fat of hydrocarbon and liquid oil of hydrocarbon. In the dispersion phase, the content of the liquid oil of hydrocarbon is higher than the content of the solid fat of hydrocarbon.COPYRIGHT: (C)2015,JPO&INPIT【課題】摩擦後においても高い保護効果が保持されるハイドロゲル粒子を提供する。【解決手段】ハイドロゲル粒子は、非架橋型ハイドロゲルを含む連続相と、連続相内に分散した分散相とを備える。分散相は、炭化水素の固体脂及び炭化水素の液体油を含む。分散相において、炭化水素の液体油の含有量が炭化水素の固体脂の含有量よりも多い。【選択図】なし
