Our Hypochlorous technology is recommended by the Roslin Institute for infection control with veterinary clinics and for the treatment and care of animals.


Hypochlorous acid (HOCl) is produced naturally in our immune systems (in fact all animals) and is the substance the cells in our bodies use to fight infections and kill invading germs and nasties. In industry it is known as electrolysed water, and is commercially made from water, salt and electricity. Hypochlorous acid is one of the most effective known biocides, killing 99.9999% of bacteria and 99.99% of viruses in seconds! As it contains no harsh chemicals or alcohol it poses no risk to humans or animals and can even be used to kill bacteria in drinking water. An amazing eco product, it is readily biodegradable dissipating to salt & water.

RenaSan Hypochlorous products are safe to use on all mammals (dogs, cats, horses, hamsters etc.), avian (budgies. Parrots, Chickens etc.) & Reptiles (Snakes, lizards, Geckos etc.).

Hypochlorous acid should be stored out of direct sunlight but does not need to be refrigerated, even when opened. It also should not be decanted into any other storage, Hypochlorous acid is light sensitive so is packaged accordingly. As it poses no health and safety concerns, there are no specific storage requirements.
