The Hypochlorous Acid Story

Aug 28,2023 | WODE Disinfectants

If you ask anybody on the street whether they know what hypochlorous acid is, chances are most have never heard of this substance before. But did you know that the first discovery of hypochlorous acid was almost 200 years ago?

Early 19th-20th century: 1834-1920s

Hypochlorous acid was first discovered by Antoine Jerome Balard, a French chemist, in 1834. By the early 20th century, medical professionals had recognized the antiseptic functions of hypochlorous acid, leading to its use in disinfecting soldiers' wounds during World War One. Additionally, medical professionals recognized how hypochlorous acid could kill bacteria in fluids, contribute to environmental sanitation, and treat conditions like diphtheria, scarlet fever, and gangrene.

Excerpt from the journal article “Antiseptic Action of Hypochlorous Acid and its Application to Wound Treatment”

Middle to late 20th century: 1940s-80s

In the 1940s, London hospitals used acidified hypochlorite solutions in aerosol form (which contain a considerable amount of free hypochlorous acid molecules) to combat airborne pathogens in the air and prevent infections. Decades later, research discovered that hypochlorous acid is naturally produced by the human body and used by the body to fight against pathogens.

In 1950, electrolyzed water (another name for hypochlorous acid) was used in the agriculture field. It was also later used in drinking water treatment and wastewater treatment in the 1980s. Around the same time, Japan also utilized it as sanitation water for its food sector. By this period, more researchers started to explore electrolyzed water as an alternative, safe sanitizer/disinfectant for food and other applications.

21st century to now: 2000s onwards

Hypochlorous acid gains further recognition in the 2000s and became more well-known. In a 2008 document “Guidance for Industry: Guide to Minimize Microbial Food Safety Hazards of Fresh-cut Fruits and Vegetables”, the FDA acknowledged hypochlorous acid as an antimicrobial agent for processing water used to sanitize fruits and vegetables. In 2017, the FDA officially authorized hypochlorous acid for food contact, allowing it to be used as an antimicrobial agent for preparing produce and meat. The EU also authorized the use of hypochlorous acid in 2021 to be used in biocides of type 1,2,3,4 and 5. This means that hypochlorous acid can be used for human hygiene (products that come into contact with the skin), animal hygiene, surface disinfection, and treating drinking water. Medical professionals also turned to using hypochlorous acid during the Covid-19 pandemic, as an alternative disinfectant that could be effective against Covid-19.

Although hypochlorous acid is safe and works fantastically as an antiseptic and a disinfectant, its limited shelf life (48-72 hours) has hindered the wide adoption and commercialization of hypochlorous acid. However, this issue has been addressed by recent technological advancements, which managed to extend the shelf life of hypochlorous acid to at least a year.

While many hypochlorous acid disinfectants have a shelf life of a year, WODE’s hypochlorous acid disinfectants last twice as long—up to two years. WODE is the only local brand in Singapore that has the longest shelf life for its hypochlorous acid disinfectants. Furthermore, WODE has a wide range of disinfectants for differing needs. We have disinfectants designed for newborns, young children, adults, and even pets. Explore our collections and find the right disinfectant for you!
