  • What is Electrolyzed Water?

3pr1Electrolyzed water is the general term referring to any solution produced by the electrolysis of water containing an electrolyte, such as sodium chloride, potassium chloride or dilute hydrochloric acid. The acidic electrolyzed water, which contains constituents with sanitizing and deodorizing effects, is produced at the anode. While at the cathode, the alkaline electrolyzed water, which contains constituents with strong cleansing effects against protein, fat and oil, is produced. Depending on the choice of electrolyte and the electrolysis methods, potable electrolyzed water can also be generated.

The acidic electrolyzed water has received approval and has been certified in the medical field under the name, strong acidic electrolyzed water, and in the field of food and food products under the name, hypochlorous acid water, by the Ministry of Health, Labour and Welfare. Furthermore, in the field of agriculture, it has been approved and specified as a Designated Harmless Agricultural Chemical, under the name, electrolytic hypochlorous acid water, by the Ministry of Agriculture, Forestry and Fisheries and the Ministry of the Environment.

To avoid confusion in the market, the Japanese Electrolyzed Water Association reached a unanimous agreement to conform with the names assigned by the government in each field, in lieu of continuing the use of specific names previously existing in the electrolyzed water industry.

 

About the Safety of Electrolyzed Water

The Ministry of Health, Labour and Welfare (Food Additive・Disinfectant) “Hypochlorous Acid Water”

PFSB/ELD Notification No. 0327004

“In regards to electrolyzed water, it is permissible to be designated as a food additive, as it is found to pose no hazard to human health.”

Marketing Activity

JEWA is promoting the use of electrolyzed water in the hygiene management of the athletes’ village and kitchen in the 2020 Tokyo Olympic・Paralympic Games.

The association continues to engage actively in negotiating the use of electrolyzed water and contributes to achieving an environmentally friendly Tokyo Para−Olympics.

Japan Green-Agriculture Club

JEWA has established the “Japan Green-Agriculture Club” to promote the use of designated harmless agricultural chemical, Electrolytic Hypochlorous Acid Water, in achieving safe and reliable agriculture. The association aids and supports all electrolyzed water user members.
