Explain hand washing with strongly acidic electrolyzed water generated from medically approved equipment

The effect of electrolyzed water on norovirus and influenza virus has been demonstrated in papers.
In a test using norovirus, 40ppm of acidic electrolyzed water has demonstrated superior bactericidal effects compared to 1000ppm of sodium hypochlorite, even though the concentration is much lower1 ) .
Furthermore, in a hand washing test using viruses of the same family, it has been demonstrated that while ethanol has a slow effect, acidic electrolyzed water has an immediate effect 2 ) .
It has also been shown to have an immediate effect within 5 seconds against influenza virus 3) .

3. Hand sanitizers for healthcare workers are limited to products registered as medical devices. Medical device approval number: 21500BZZ00386000 (manufactured by Hoshizaki Electric Co., Ltd.) It was approved in 1996 after safety tests such as cytotoxicity, mutation, chromosomal aberration, percutaneous toxicity, cumulative skin irritation, ocular mucosa, oral cavity, and mucous membrane.

Data on the similarity of hypochlorous acid water and sodium hypochlorite

<Food field>

In the mass cooking facility hygiene management manual, sterilization with sodium hypochlorite is 200mg/l for 5 minutes or 100mg/l for 10 minutes, but there is no mention of treatment time etc. for hypochlorous acid water. , We will show you a guideline for the treatment method that can provide the same effect as sodium hypochlorite. The following is an example1) of food sterilization test results conducted by participating member companies of our association. By performing appropriate treatment, it is possible to obtain a bactericidal effect equivalent to that of sodium hypochlorite in a short period of time.

In addition, from the same point of view, we have created a specific manual on how to process Chinese cabbage for light pickling.

The materials are published under the guidance of the Safety Division, Pharmaceutical and Food Safety Bureau, Ministry of Health, Labor and Welfare. (January 23, 2013)
