HOCl

General Info

 

About HOCl

Hypochlorous acid is naturally produced by white blood cells of all mammals. It plays an important role in the immune system killing pathogens through oxidation and chlorination.

Hypochlorous acid can also be produced through a process called electrolysis. Electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Specifically engineered elecrolysis cells can generate a solution of free chlorine species by running electricity through NaCl (table salt) and water. The oxidants hypochlorous acid (HOCl) and hypochlorite (OCl-) are formed at the anode. If the pH of the solution is weakly acidic to neutral, the free chlorine solution will be dominated by hypochlorous acid. 

Hypochlorous is a powerful oxidant and is 100 times more efficient at killing microbial pathogens than sodium hypochlorite (aka. chlorine bleach). 

Safe on Eyes and Skin 

Hypochlorous acid does not cause irritation to eyes and skin. Even it were ingested it causes no harm. Because it is so safe, it is the ideal sanitizer for direct food sanitation and food contact surfaces. It is also ideal in healthcare where it is used for wound cleansing, eye drops, and patient room disinfection replacing toxic chemicals such as bleach and quaternary ammonium (quats). 

Non-Toxic, Non-Hazardous

Sanitation chemicals distributed in concentrated form are toxic and can be hazardous. Contact with skin or inhalation of fumes can cause irritation. These risks do not exist with hypochlorous acid. Electrolyzed water systems generate hypochlorous acid from just table salt, water and electricity. No personal protective gear is required.

New Technology & Research Of

Hypochlorous Acid

The use of chlorine for disinfection has been researched for over 100 years. It has been an undisputable fact that hypochlorous acid offers far superior disinfecting properties than sodium hypochlorite (chlorine bleach). One of the most well known authorities for the use of chlorine as a disinfectant is White's Handbook of Chlorination. This book is comprehensive in explaining the chemistry and effectiveness of chlorine and alternative disinfectants.

The challenge has been in engineering a system for producing a free chlorine solution that is dominated by the molecule of hyopchlorous acid (HOCl) rather than sodium hypochlorite (NaOCl-). The development of electrolysis cells for generating electrolyzed water became a huge innovative breakthrough in the 1970s. Since then, improvements in electrolysis cells have been made that can generate a solution of free chlorine that is near 99% hypochlorous acid and that is stable. 

One of the most recent improvements has been the development of single cell technology to replace membrane cell technology allowing for the production of just one stream of solution at a near neutral pH. Prior technology used membranes and high pressures that forced two streams to be generated, an unstable anolyte of hypochlorous acid and an unstable catholyte of sodium hydroxide. With the development of single cell technology, a stable solution of just anolyte can be produced yielding a solution of near 99% stable hypochlorous acid. 

Over 30 years of research exisits for the use of hypochlorous acid and new research is being published every year. Recent research has focused on the use of hypochlorous acid for sanitzing food and food processing facilities. Research has also been done on poultry farms, water treatment and disinfection, and healthcare related applications such as wound care and equipment sterilization. 

How Does

Hypochlorous Acid

Kill Microbial Pathogens?

The molecule of hypochlorous acid is HOCl. This molecule is unique in that it is neutrally charged unlike hypochlorite (OCl-) which is negatively charged. So why is this important? 

Disinfectants and microbial pathogens interact with each other similar to magnets. If you bring together two negatively charged magnets, they will repel each other. Bacteria and hypochlorite (OCl- aka. bleach) are both negatively charged and behave like two negatively charged magnets repelling each other. Hypochlorous acid (HOCl) is neutrally charged and is not repelled by bacteria. HOCl easily penetrates the walls of the bacteria and destroys them with its strong oxidation potential.

What is HOCl?

HOCl is the scientific formula for hypochlorous acid, a weak acid similar to that of a mild citrus juice. HOCl is made naturally by white blood cells in all mammals for healing and protection. HOCl is a powerful oxidant that is effective against invading bacteria, fungi, and viruses. Generating HOCl by running electricity through a solution of saltwater was discovered in 1970s. HOCl is now used in healthcare, food safety, water treatment, and general sanitation.
