Nemesis eH2O

Nemesis eH2O is a powerful anti-viral, broad spectrum disinfectant; killing 99.99% of harmful bacteria. It is also highly effective against viruses, bacteria & fungi. Normal application is by spraying or fogging any surface, including as an antiseptic on sensitive skin. With stabilised hypochlorous (weak acid HOCl) as its active ingredient, Nemesis eH2O (also known as ‘E-H2O’) contains no harmful chemicals or alcohol, so no personal protective equipment (PPE) is necessary for normal use.

  • Compliant – European Biocidal Products Regulations (BPR product Types 1, 2, 3, 4 & 5) and BS EN 1276, BS EN 13697, BS EN 13704, BS EN 14476 and BS EN 1656.

  • Effective – Spraying or fogging delivers effective deactivation of harmful pathogens. Click here to discover why 99.99% is so important.

  • Fast – Kills micro-organisms within seconds – much faster (and 80 – 100 times more effective) than bleach and with broader spectrum efficacy than alcohol based sanitisers and disinfectants. Nemesis eH2O is also gentle on the skin, unlike bleach or alcohol.
  • Versatile – Approved for use as a spray on frequently used items, or as a fog for larger spaces. Approved applications include human hygiene (skin & scalp), hard and soft surfaces, materials, equipment, furniture and textiles (does not discolour). Approved for veterinary hygiene, all food and feed areas, and drinking water for both humans and animals.

  • Secure – in the knowledge that E-H2O is not hazardous to health. Contains no toxic chemicals. No PPE required. pH neutral. The only by-product of disinfection is slightly salty water – no harmful waste and no threat to the environment.



The coronavirus pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in enormous growth in demand for Nemesis eH2O, so we have greatly increased the UK manufacture of stabilised hypochlorous acid (HOCl).

Please note that HOCl is included in the US EPA’s list of active ingredients for use against SARS-CoV-2. Nemesis eH2O is supplied in ready-to-use spray bottles, as well as in containers for use with fogging machines.

It is available online and in chemists all over the UK – see our Contact page for links.

(some stores are currently limiting retail customers to one of our anti-viral disinfectant bottles per order)
