1. Chemical reaction by electrolysis of sodium chloride aqueous solution (brine)    The following chemical reactions are
used to produce “ sodium hydroxide” and “chlorine” , which are important basic chemical substances in the industrial field .
From now on it is commentary that by electrolysis " hypochlorous acid " of the product is also the underlying become reaction formula.
 
Anodic reaction: 2ClCl2 + 2e Chlorine production※1
Cathodic reaction:2H2O + 2Na + 2e→ H2 + 2NaOH・・・generation of ... sodium hydroxide
Mixed water :2NaCl + H2O → Cl2 + H2 + 2NaOH・・・generation of ... sodium hydroxide ※2
    (Or diaphragmless electrolysis)
Hypochlorous acid formation  
※ 1 , 2 produced in the " chlorine gas ( Cl 2 )" is present by the following reaction formula in water hypochlorite or a hypochlorite ion. The abundance ratio of hypochlorous acid and hypochlorite ion varies depending on the pH of the aqueous solution.
 
Cl2 + H2O ↔ HCl + HOCl・・・by the pH Ri proportions are changed
OCl + H
 
The chlorine gas dissolved in the aqueous solution becomes “ hypochlorous acid ( H 2 O 2 Cl 2 ) ” in the acidic region and exists as “ hypochlorous acid ion (2 OCl ) ” in the alkaline region .
"Hypochlorite ( H O Cl )" is " hypochlorite ion ( OCl - )" of about 80 lifting the fold sterilizing power one.
 
3. Formation of sodium hypochlorite (a general disinfectant)
 
At present, sodium hypochlorite ( NaClO ), which is frequently used as a general disinfectant, is produced by passing chlorine gas through an aqueous sodium hydroxide solution.
Cl 2 + 2 NaOH → NaCl + NaClO + H 2 O
 
Sodium hypochlorite is alkaline, and most of the bactericidal components are dissolved in the form of “ hypochlorite ion ( OCl ) ” . Hypochlorous acid to become more likely to be released as chlorine gas becomes acidic region, distribution as an alkaline aqueous solution , and has high stability.
However, the main component " hypochlorite ion ( OCl - ) " is "hypochlorite ( HOCl compared with)", has low bactericidal activity, should be used at a certain high concentration, protection glasses in use , Gloves, masks, etc. are necessary , and chlorine odor is likely to remain after use .
 

As a familiar product, "Haiter", "Kabikira", "Milton", and "Pyurakkusu" there , have not even Re of product attention Kakigaa such as "Do not mix danger" Ru. 

When these products are mixed with acidic substances such as toilet detergents containing hydrochloric acid as the main component, toxic chlorine gas is generated due to the following chemical reaction, which is very dangerous . Fatal accidents due to the mix the detergent in the bathroom , such as because what is happening is also required extreme caution when handling it . (It is dangerous and prohibited to apply substances containing a lot of vinegar, citric acid, and carbonic acid.)

NaClO + 2HCl NaCl + Cl 2 + H 2 O

3. Slightly acidic hypochlorous acid water = " hypochlorous acid water
Brine of electrolysis in, the raw water appropriately adding hydrochloric acid in a state when performing diaphragm-free electrolysis produced aqueous solution, sodium hydroxide (NaOH) is the hydrochloride is neutralized, the strongest sterilizing power " fine acidic "area next to," hypochlorous acid ( HOCl ) " was composed mainly of " slightly acidic hypochlorous acid solution " Do that.
 
2 NaCl + 2HCl + H 2 O → HCl + Na OH + HClO + H 2
( NaCl + H 2 O )
 
Anodic reaction: 2 Cl Cl 2 + 2e
Cl 2 + H 2 O ↔ HCl + HclO
Cathodic reaction: 2 H 2 O + 2 Na + + 2e - → H 2 + 2NaOH
"Slightly acidic hypochlorous acid water" is compared with "sodium hypochlorite", the main component is hypochlorous acid ( HOCl because it is), approximately 80 times the germicidal there Ri , at low concentrations It can be used, has almost no taste or smell, and can be used without protective equipment such as protective glasses, masks and gloves .
Further, "slightly acidic electrolyzed water" is obtaining good results in the following safety test, high safety.
 ・ Acute oral toxicity ・ Cumulative skin irritation ・ Eye irritation
-Mutagenicity test-Subacute toxicity-Trihalomethane production test (see Section 4)
 
 
4). " Trihalomethane " and "Bromic acid"    
 
 " Trihalomethanes " or "bromate" is an impurity and chlorine reaction compounds produced by in , kind of trihalomethanes is chloroform and bromodichloromethane , potassium bromate is the World Health Organization ( International Agency for Research on Cancer of the WHO) (IARC ), Group 2B = “ possibly carcinogenic”.
 (The United States in the EPA, group B2 bromate "= human classification to there is a high possibility of carcinogenic against theft")
 
In Japan, which sterilizes tap water with chlorine, the standards for trihalomethane and bromic acid in tap water are determined by the Water Supply Law as follows.

Total trihalomethane : 0.1 mg / L or less             

Chloroform : 0.06 mg / L or less                           

Dibromochloromethane : 0.1 mg / L or less             

Bromodichloromethane : 0.03 mg / L or less             

Bromoform : 0.09 mg / L or less                           

Bromate : 0.01 mg / L or less

Therefore, in Japan, when producing hypochlorous acid water by electrolysis, substances other than salt and hydrochloric acid should be used.

Mixing is prohibited, and the purity of salt and hydrochloric acid, and evaporation residues are strictly regulated.

(Gazette: Food Safety 0426 No. 1 issued by the Ministry of Health, Labor and Welfare on April 26, 2012)

Salt purity: 99% or more, chlorine grade: food additive formulation 

Evaporation residue: 0.25% or less

[Reference information]

Are generally distributed " sodium hypochlorite " is the raw material purity of low , residual from the very high chlorine concentrations high concentration has been found to contain "bromate".

The bromate content of products sold by certain pharmaceutical companies is disclosed as " 26mg / kg " .

(2600 times the water supply standards)

5). "Chlorine -based germicide and" the other aqueous solution mixing of
 Above , as shown in, chlorine-based disinfectants react with impurities such as organic matter, a carcinogenic substance was to produce because in Japan has been multiplied by strict regulations with respect to the impurity.
In market " hypochlorite sodium " or saline solution was electrolyzed in diaphragm-free manner " electrolytic hypochlorite water " to enhance the germicidal power of the " acidic " in water solution and may it be done miscible .
 
As mentioned above, when an aqueous solution containing a lot of organic impurities, such as “VINEGAR”, is mixed as an acidic aqueous solution for the purpose of pH adjustment , carcinogenic substances such as “trihalomethane” and “bromate” are produced. There is a risk of being.

In addition, the acid resistance of the aqueous solution of the mixed If you have, toxic because there is a risk of chlorine gas is produced, the incorporation of an aqueous solution of the acid does not go never.

 

 5). Summary    

Hypochlorous acid water produced by electrolysis is highly expected as a next-generation disinfectant because of its high sterilizing power and safety .

To distributed as conventional fungicides "solution" is to be long-term storage is possible "high stability" is needed, introducing a device for generating in front of the time use "hypochlorite water " , high sterilization force and" return immediately to the nature "in exchange =" life is short "a good understanding of the characteristics that use and there is a need.

In order to use this wonderful electrolyzed water effectively, we expect you to fully understand the characteristics described in this document .
