The arrival of the coronavirus created an enormous amount of interest in hypochlorous acid (HOCL) as a disinfection product, to see if it could be used within a wider prevention and protection strategy to help reduce the spread of COVID-19 (Persistence of coronaviruses on inanimate surfaces).

Hypochlorous acid occurs naturally in the human immune system. It’s what the cells in our bodies use to fight infections. Our hypochlorous acid products are produced from three everyday components: water, food grade salt, and electricity. When you use hypochlorous acid for disinfection, it oxidises and is consumed. The only by-product is slightly salty water. Our hypochlorous acid products have been independently laboratory-tested as completely safe for humans and without health risks. They are even being used to treat drinking water. Our products are non-flammable, non-toxic, can be handled without protective equipment and are easy to dispose of. They’re kind to humans and animals, and kind to the environment.

For years, many countries around the world have been reaping the benefits that HOCL brings to healthcare; food processing and manufacturing; water treatment; and water recycling, along with the improved hygiene standards it offers within the cleaning and housekeeping sectors. Outside the UK, the healthcare sector has used HOCL to help people breathe who have contracted COVID-19: one dying patient is reported to have recovered from pneumonia when HOCL was used to aid his breathing. HOCL is used for wound care applications like ulcerated wounds, for patients who have contracted an MRSA infection, or on diabetic skin ulcers. Wounds always heal faster when treated with HOCL, as it prevents biofilm from infecting the wound and fights off any airborne invaders that try to populate the wound.

Sadly, here in the UK we have been very slow to adopt electrolysed water technology for patient treatments or as a replacement for sodium hypochlorite (SH), which is an irritant and is corrosive, necessitating the use of PPE. SH is used for many housekeeping, clean up and disinfection applications within wards to clear up blood, faeces, or contamination incidents. HOCL is able to provide safe and superior disinfection capabilities for any tasks that SH is already used for; and can be safely used without PPE, although we recommend that nursing staff follow their hospital’s health and safety recommendations for using PPE with the individual chemical products. HOCL liquid, is used against COVID-19 by spraying or misting surfaces; it can be dry fogged in a Smartmister within occupied working environments, or even used within decontamination tunnels or chambers to disinfect people who are entering or leaving work.

During this pandemic we have been misting, by using the desktop smartmister units within workplaces, offices, schools, hairdressers and dental surgeries, to name but a few applications where people have benefited from the use of our non-toxic HOCL, which can be safely breathed in over the course of a working day. The safety our HOCL product offers can be clearly seen within our safety data sheet: it is unique when compared to the many other chemicals within the market, as the safety data will clearly show.

Breathing in the HOCL is not harmful in anyway, and a Risk Assessment verifies this fact, so by inhaling it, this will provide your airways and lungs with residual protection by having the HOCL within your body, to counteract the Covid-19 if you were to inhale it.

HOCL Hypochlorous acid is endorsed by BUPA and has been proved effective in their care homes (see case study)

HOCL is certified by the USDA as a product allowed to be used in organic production and handling. (see Policy Memorandum)
