Safe and Efficient Production of Hypochlorous Acid

Technology Overview

The technology owner has developed a weakly acidic hypochlorous acid manufacturing process that uses a patent pending buffering technology which does not use acid and have minimal chlorine gas production. 

There are known issues with hypochlorous acid produced using the traditional electrolytic method or two-liquids method, such as low preservation stability or chlorine gas generation of during the manufacturing process. Therefore, it used to be difficult to produce high purity, concentrated liquid hypochlorous acid. In the process of manufacturing the hypochlorous acid, the above issues were overcame by using the Buffering Technology and successfully manufactured high purity, concentrated liquid hypochlorous acid.

The buffering technology is a technology to produce weakly acidic hypochlorous acid water which is even safe to drink.

Features of our technology.

    • pH does not decrease to the level at which chlorine gas is to be generated.
    • Concentration can be easily controlled.
    • Certified by technology provider country's major government agency.
    • Hard to salt and do not affect the equipment.
    • Hard to cause whitening phenomenon.

Technology Features & Specifications

The “Buffering Technology” is a innovative and new method for producing weakly acidic hypochlorous acid water. It uses the buffering function of buffering materials to generate mildly acidic liquid sodium hypochlorite from sodium hypochlorite without the help of neutralizers such as hydrochloric acid.

High purity, concentrated weakly acidic hypochlorous acid water is produced by eliminating sodium ion from the raw materials of water and sodium hypochlorite by passing them through the buffering materials of a pH buffering layer. Both sodium hypochlorite and the buffering materials are authorized food additives in Japan. The buffering material stabilizes the product at the ideal pH and also eliminates impure substances such as calcium and magnesium contained in water or sodium hydroxide.

The acid produced has been tested at independent third party laboratories for safety and disinfection efficacy:

1. " Akita Prefectural Center of Analytical Chemistry ltd."

  • Water examination result: Highly safe meeting the main “water quality standard for drinking water” under the Water Supply Act.(Japanese Law).

2. “Kitasato Research Center for Environmental Science”

  • Inactivation test of bovine diarrhea virus (alternative hepatitis C virus) ,
  • Bactericidal efficacy test of spore forming bacteria (Bacillas subtilis)
  • Elimination performance test of airborne virus (alternative influenza virus), September 2013

Potential Applications

  • Prevention of food poisoning.
  • Disinfection/deodorization. 
  • Prevention of hospital infection.
  • Hygiene control at plants.
  • Collective infection prevention for students.
  • Measures against foul odors and bacteria of livestock farmers.
  • Measures against air pollution in China and elsewhere.
  • Use in the medical field such as treatment of gangrene, washing  endoscope ,and disinfection of wounds by bedsores.
  • Measures against biological weapons.

Market Trends and Opportunities

In China,India,etc.,there is a huge market as a hygiene measure accompanying rapid economic development and population increase. In the medical field, the number of patients suffering from gangrene due to diabetes and bedsores is enormous. Washing endoscopes requires a considerable amount of water. In general, cleaning and disinfection is required daily for numerous industries and a safe, green and efficent production method is needed. 

Customer Benefits

  • Low initial cost.
  • Can be manufactured with simple equipment.
