Superior Disinfectant Water to Alcohol and Bleach
Safe and eco-friendly "Hygienic Water"
Hygienic Water is a hypochlorous acid solution effective for disinfection and deodorization.
It is made from tap water, sodium hypochlorite, and dilute hydrochloric acid.
With a mild acidity (pH 5.5–6.5) similar to human skin, it is safe to use.
It has superior disinfecting power compared to alcohol and is proven effective against influenza and norovirus.
The effectiveness of hypochlorous acid varies significantly depending on pH.
The highly effective hypochlorous acid (HClO) has minimal presence at pH 9–10.
Hygienic Water is adjusted to pH 5.5–6.5, ensuring high levels of active chlorine while being gentle on the skin.

■ Features
・High Disinfecting Power
Hypochlorous acid water is effective against Escherichia coli O-157, methicillin-resistant Staphylococcus aureus (MRSA), Salmonella, and Bacillus cereus.
Studies have demonstrated the usefulness of sodium hypochlorite against influenza and norovirus.
Hypochlorous acid, recognized as having higher disinfecting power than sodium hypochlorite, is also considered effective against these viruses.

・Decomposes Odor-Causing Substances for Deodorization
It breaks down odor sources such as tobacco, garbage, and toilets.
Recommended for those who dislike scented deodorizing agents.

・Reverts to Water, Making It Safe for People and the Environment
After breaking down bacteria and viruses (organic matter), it turns back into water.
It is gentler on hands than alcohol and bleach, making it ideal for disinfecting household items and baby products.

・Manufactured by Kansai Chemical Co., Ltd.
Hypochlorous acid water has a slight chlorine-like odor but appears identical to water.
Although it requires specialized equipment to produce, misinformation claiming it can be made easily has spread.
Additionally, some counterfeit products labeled as "hypochlorous acid water" actually contain calcium hypochlorite or sodium hypochlorite.
Hygienic Water has been manufactured and sold by Kansai Chemical Co., Ltd. since 2014 as a norovirus countermeasure.
Third-party testing has verified its effectiveness, ensuring a trustworthy purchase.

・Production Method
Hypochlorous acid water is typically produced in two ways:
- Electrolysis of saline solution
- Adjusting the pH of sodium hypochlorite
Hygienic Water is produced by adjusting sodium hypochlorite to pH 5.5–6.5.
Only electrolyzed hypochlorous acid water is recognized as a food additive.*
Diluted household chlorine disinfectants (e.g., kitchen bleach) are entirely different.*

■ Recommended Applications
Since it is safe even if accidentally ingested, it can be used for disinfection and deodorization in various settings:
・Mask disinfection
・Door handle disinfection
・Toy and baby bottle disinfection
・Pet odor removal
・Hospital waiting rooms and equipment disinfection
・Disinfection and deodorization of chairs and desks
・Deodorization of smoking areas
・Car seat deodorization
・Store disinfection
・Dish disinfection
・Vegetable disinfection
