Abstract
Water-electrolysis of tap water without membrane followed by passing through
activated carbon filter was conducted to produce electrolyzed-reduced water having
approximately neutral and reductive characteristics. It was found that the electrolyzedreduced water is advantageously e#ective in preventing oxidation of fish-lipid. Daily
bathing in the water for , months decreased ORP (oxidation-reduction potential) and
improved the elasticity of the skins. The water would contribute to suppression of
oxidation/aging of the skin. Moreover, treatment of bleached hair by the water resulted
in improvement in fluency and gloss. We can expect, therefore, that fresh hot spring
water has same reductive characteristics as that of the electrolyzed-reduced water.
Key words : Water electrolysis, Reduced water, Artificial hot spring water, ORP, Aging,
Skin, Hair
