Welcome to the HOCl Trust
Hypochlorous Acid (HOCl) is a truly remarkable substance that occurs ubiquitously throughout the natural world. It has some phenomenal properties, many of which are not yet fully understood but are of great value to mankind in both developed and underdeveloped countries around the world.
The HOCl Trust exists to champion HOCl as a safe, versatile antimicrobial: educating the public and professionals via evidence-based resources, advocating its inclusion in global health policies, and supporting practical adoption—from clean water and hospital sanitation to home and veterinary applications.
FIND OUT MORE ABOUT HOCL
From the Trust Archives...
We have a large repository of scientific investigations on the action of HOCl on a wide variety of health problems, including some very old papers.
These have been in the public domain, but we feel it's time everyone has access to them, as they are still relevant.
(This is an ongoing project, starting 16th October 2026...please bear with us as we upload the archival papers...)
HOCl as an antiseptic
HOCl and leg ulcers
This poster was shown at the Wounds UK conference in 2004, at the Harrogate International Conference Centre. It summarises a clinical research project that investigated the effect of HOCl (at 160 ppm) as a leg ulcer wound wash on pathogenic bacteria and human skin cells. HOCl was highly effective in reducing the level of bacteria, easing the pain of infection and promoting healing. Contrast this outcome with recent reviews on the effect of non-HOCl antiseptics on the skin. Examples below.
