Use the Search facility to find fascinating facts about this unique molecule, HOCl


HOCl was thoroughly and exhaustively tested for efficacy, and to quote Charles Cocking, the founder of the HOCl Trust:

At first evaluation:

Dr Joseph Selkon of Oxford University called me after 3 days:

“Mister Cocking, what is this stuff you’ve given me? It’s killing bugs faster than we can count!”

Then after extensive testing:

“The product is now evaluated against the complete range of relevant EN codes and has exceeded the required performance in all cases."

Is HOCL the ideal disinfectant?

High level of microbial control including “difficult to destroy” prions

Fast acting

Cheap and easy to make, readily available, and easily stored

Easily applied and utilised

No harmful residues or metabolites

No solvents or detergents

Safe on food

In medical use, no acute or long term adverse effects

No harm when released into waste water, no eco-toxicity issues.


Sanitizing agents for virus inactivation and disinfection

"Compared to sodium hypochlorite, sodium dichloroisocyanurate [NaDCC] has disinfectant activity that persists for longer, is more tolerant to the presence of organic material, and has a higher disinfectant efficacy overall."

Aerosol Disinfection Capacity of Slightly Acidic Hypochlorous Acid Water Towards Newcastle Disease Virus in the Air: An In Vivo Experiment

"All in all, our results confirm the fast and efficient aerosol disinfection capacity of SAHW against NDV in the air and show that this substance can indeed protect chickens from infection."

Stabilized Hypochlorous Acid Disinfection for Highly Vulnerable Populations

"We review here an emerging technology based on hypochlorous acid (HOCl), with emphasis on a novel pure and stable form (Brio HOCL™), that inactivates viruses, bacteria, endospores, and fungi, is safe for human tissues (including eye, lung, and skin), is environmentally benign requiring no toxic waste disposal or hazardous material management, and yet is capable of degrading the infectivity of highly-resistant prions at a Log Reduction Value (LRV) of >5, equating to roughly a 99.999% elimination."

Hypochlorous Acid for disinfection, antisepsis, and wound care

"Based on the assessment, this Reviewer is of the opinion that - in principle -hypochlorous acid can be recommended for inclusion in the Model List as disinfectant. The Expert Committee should consider whether its listing can be recommended now or should be postponed when data from current ongoing R&D project evaluating its use in hospital settings will be available."

Hypochlorous Acid - A Review

"HOCl ...comprises many of the desired effects of the ideal disinfectant: It is easy to use, is inexpensive, has a good safety profile, and can be used to disinfect large areas quickly and with a broad range of bactericidal and virucidal effects."

Evaluation of Hypochlorous Acid Fogging: An Alternative Disinfection Method

"These results suggest that hypochlorous acid (purchased or homemade), when applied as a fog, is effective against certain bacterial and viral pathogens, namely E. faecalis and H1N1."
