Hypochlorous Acid - HOCl (Electrolyzed Water)                      

What is Hypochlorous acid?

Hypochlorous acid (also known as Electrolyzed Water) is nature’s oldest disinfectant, and it happens to be walking around in about 7.5 billion people right now. As in inside all humans, this very moment.

Why? It’s the substance your white blood cells produce to fight off infections. It’s also the active ingredient in electrolyzed water, which is an industrial technology used for green cleaning and sanitizing. Electrolyzed water is made when electricity is used to change the chemical structure of salt, water & vinegar into a green cleaner as effective as bleach, but with no harmful chemicals, fumes or residues.

How is hypochlorous acid made?

To make hypochlorous acid is pretty simple chemistry. Start with precisely the correct proportions of three ingredients: salt, water and vinegar. You may remember that a salt molecule is made up of the elements sodium and chloride (NaCl) and a water molecule is made up of hydrogen and oxygen (H2O). When an electrical current is applied to the solution, the molecules break apart and the elements form two new molecules:

Hypochlorous acid (HOCl)

Nature’s super powerful disinfectant, and also the ingredient that gives bleach its anti-microbial power. When the pH of the solution is lowered to the correct level, HOCl is created, exactly the same substance that is your immune system’s germ fighter. So when you take your child to that indoor play area/petrie dish – your white blood cells get to work creating hypochlorous acid.

Healthcare & medical uses of hypochlorous acid

Hypochlorous acid is so gentle that it has several uses in the healthcare and medical space. It’s FDA approved for use in wound healing, wound care and eye care products and is also common in veterinary care products. It’s even used to eradicate biofilm. There has been extensive research on the gentleness and efficacy of HOCl when it comes to killing bacteria. It is so trusted and effective, that hospitals use it as a disinfectant in both the US and Japan.

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

Coronavirus Disease (COVID-19)

Coronavirus Disease 2019 (COVID-19) is a novel virus. It causes severe acute respiratory syndrome.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the agent responsible for a surface-to-surface communicable disease.

On contact with the virus, the hypochlorous acid (HOCl) changes the protective protein coat, which loses its structure and aggregates, forming clumps of proteins with other viruses. Currently, the US Environmental Protection Agency has recommended hypochlorous acid (HOCl) disinfectant against COVID-19.

The mechanism of disinfection involves the destroying of the cell wall of microbes or viruses, allowing the disinfectant to destroy or inactivate them.

Hypochlorous Acid listed at EPA's List N

Environmental Protection Agency (EPA) confirms that Hypochlorous Acid (HOCl) eliminates 99.99% of COVID-19 in just 20 seconds, faster than any disinfectant included on the EPA List N.

Hypochlorous Acid (HOCl) is the disinfectant approved for use by our robots

After conducting laboratory and operation tests with various disinfectants considered for the combat of COVID-19, our company opted to homologate hypochlorous acid as the disinfectant to be used by our robots.

Spray disinfection of hypochlorous acid HOCl) eliminates 99.99% of COVID-19 in just 20 seconds, without harming people's health, and is faster than any other disinfectant included on the EPA List N.

Safe on Eyes and Skin - Non-Toxic, Non-Hazardous

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).

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.

Why is HOCl more efficient at killing pathogens?

Hypochlorous Acid (HOCl) vs. Sodium Hypochlorite (Chlorine Bleach)

  • The Hypochlorite ion carries a negative electrical charge, while hypochlorous acid carries no electrical charge.
  • The hypochlorous acid moves quickly, able to oxidize the bacteria in a matter of seconds, while the hypochlorite ion might take up to a half hour to do the same.
  • Germ surfaces carry a negative electrical charge which results in a repulsion of the negatively charged hypochlorite ion to the area of the germ surfaces, making hypochlorite ion less effective at killing germs.
  • The hypochlorous acid' slack of electrical charge allows it to more efficiently penetrate the protective barriers surrounding germs.

New Technology & Research

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.

Hypochlorous acid is also 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).
