摘要:
A coral is washed with purified water or tap water, and a crushed coral is heat-treated. Proteins and other organic matter are incorporated between calcium molecules in the coral skeleton, and the organic matter is decomposed and released as volatile components. In the skeleton from which organic matter is released, a calcium skeleton having a porous structure is formed, and the surface area of pores is increased. A hydrogen gas can be retained in the structure by adsorbing a hydrogen gas to the pores in such a calcium skeleton a porous structure (micropores). The resulting coral powder, with which ions dissolved in water are easily extracted, shows a low oxidation reduction potential when dissolved in water.

The present invention discloses a process for producing an electrolytic water, wherein a to-be-electrolyzed water containing less than 0.1 mM of a water-soluble inorganic salt, 0.05 to 0.5 mass % of a hydroquinone derivative and 1 to 50 mM of L-ascorbic acid or a derivative thereof is fed into a diaphragm-free electrolytic cell of continuous flow type at a flow rate of 5 to 3,000 l/min and electrolysis is conducted continuously at a current density of 0.003 to 0.1 A/cm2. The process can produce an electrolytic water having a high skin-whitening effect owing to the reducing action of L-ascorbic acid and the melanin formation-suppressing effect of hydroquinone derivative.
