PROBLEM TO BE SOLVED: To provide mixed water of camellia oil and water formed by dissolving the camellia oil into water to be mixed together by using porous high-purity silica, and then allowing the camellia oil and water to be fused together so that the camellia oil is not separated from water.SOLUTION: In mixed water of camellia oil and water formed by dissolving the camellia oil into water to be mixed together by using porous high-purity silica obtained by fumigating and firing woody cell walls formed by drying a plant, the camellia oil and water are fused together so that the camellia oil is not separated from water.COPYRIGHT: (C)2017,JPO&INPIT【課題】 本発明は、多孔質高純度シリカを使用し、椿油を水に溶解して混合する。然る後に、椿油と水が融解して椿油と水が分離しない椿油と水の混合水。【解決手段】 植物を乾燥した木質系細胞壁を燻蒸焼成して得られる多孔質高純度シリカを使用し、椿油を水に溶解して混合する。然る後に、椿油と水が融解し分離しないことを特徴とする椿油と水の混合水。
