Q1How is JcoNAT different from conventional disinfectants?

It is a naturally existing disinfectant, and so is free of alcohol, preservatives, fragrances, and does not contain harmful chemical additives like Bleach does. Its active ingredient, HOCl, is effective against three major pathogens, including bacteria, viruses and fungi and is 80 times more effective as a disinfectant compared to the same concentration of bleach, which is a harmful substance.

Alcohol ‘s rapid evaporation causes it to only provide temporary disinfecting.

Furthermore, HOCl quickly restores back to H2O and so is harmless to our environment. For more details about HOCl, please see Why HOCl .

Q2Is there any proof that HOCl and JcoNAT are effective?

Publications by organizations like the US Food and Drug Administration (FDA), Japan's Ministry of Health, and the U.S. National Library of Medicine confirm that HOCl is effective as a disinfectant.

Specific testing of JcoNAT solution has been carried out in Labs the US and the UK on many types of pathogens and confirm that it can kill more than 99.99% of many types of enteroviruses and influenza viruses (e.g. salmonella and H1N1).

Furthermore, In 2020 we tested JcoNAT in an independent UK Laboratory for its effectiveness against all Enveloped viruses which includes SARS-CoV-2, and show that JcoNAT can disinfect 99.99% in under 15 seconds.   JcoNAT has also passed the EN14476 standard.   For testing details please refer to: Reference .

Q3What is JcoNAT made of ?

JcoNAT is a multi-use antiseptic and disinfectant. It has powerful antibacterial, antiviral and antifungal properties.  

Since its active ingredient is HOCl (Hypochlorous acid:  see Why HOCl for a more detailed information), it is much safer and more powerful than conventional disinfectants such as  Chlorine, Alcohol, etc.  

Q4What is HOCl and why HOCl?

HOCl (Hypochlorous acid) is the substance that cells in our body use to fight infections and kill invading pathogens.

It is not only one of the most effective known biocides capable of killing 99.99% of all pathogens, it is also the safest one.

It used to be a challenge to manufacture HOCl that could stay stable and keep its disinfecting properties.

Researchers in Japan and the West were finally successful in designing production equipment to achieve this, and so bottled form HOCl is now commercially available from companies such as JcoNAT.

Q5How is JcoNAT different from some products claiming to be HOCl based product?

Some products in the market that use the terminology “HOCL” are actually hypochlorite based.

Hypochlorite based products are those that contain a mixture of hypochlorous acid and sodium hypochlorite at an acidic pH. These products tend to be unstable and can decompose rapidly.Sodium hypochlorite is corrosive and can damage fabrics for example.

JcoNAT’s active ingredient is only hypochlorous acid (HOCL) and developed over the years to have long shelf life, stable, and safe. JcoNAT’s effectiveness as a disinfectant has been validated by independent labs in the US and the UK. Please see Reference .
