Alkaline ionized water refers to water generated from drinkable water (potable water conforming to the directives of the tap water quality standards) by electrolysis using water electrolyzer for home-use called " alkaline ionized water apparatus " . The structure of alkaline ionized water apparatus was explained from the viewpoint of the water purification functions and the electrolysis of the water.
Alkaline ionized water (potable alkaline electrolyzed water) was reviewed in terms of historical background, scientific and social basis of safety and physiological effect. Perspectives are also discussed.
Basic studies were carried out in order to establish a practical cleaning system for repetitive reuse of face masks by using strongly alkaline electrolyzed water (alkaline EW) and slightly acidic electrolyzed water (acidic EW). Showering with alkaline EW resulted in a markedly effective reduction of organic materials and their smells consisting of olive oil mixed with one of dry yeast, curry powder and blue cheese which were smeared on the surface of a rubber. Feline calicivirus as an alternative to norovirus, was totally inactivated by a consecutive showering with alkaline EW followed by acidic EW.
