The magic of Hypochlorous Acid Water
Overview
Hypochlorous acid water (HOCL) is a totally safe, non-toxic highly effective bacteria killer. The technology is different to bleach (sodium hypochlorite) and other sterilisation products on the market as it does not relay on high toxicity to kill bacteria.
Hypochlorous acid is a colourless and tasteless compound that is naturally active in the human body. Bacteria and foreign bodies that invade the human body are decomposed by the activity of a modified form of hypochlorous acid. SpraySafe's hypochlorous acid water products use the same sterilisation principle as white blood cells and can instantly kill bacteria in the skin's epidermis preventing bacteria from invading your body, preventing deeper infections.
How HOCL kills bacteria
In the process of killing bacteria and virus's, hypochlorous acid first attacks the shell of the pathogen, as the hypochlorous acid molecule is small and has no charge, it can pass through the cell wall to penetrate into the bacteria body. The proteins, nucleic acids, enzymes, etc. undergo oxidation reactions, which destroy the enzyme system of the bacteria and hinder its metabolism, thereby killing pathogenic microorganisms.
The chemistry behind hypochlorous acid water-
Due to its mild acid state with a pH value between, 5 and 6.5 the chlorine concentration of hypochlorous acid water is effective from a very low 10-30ppm (100 times more powerful than bleach)
The above explains the “Equilibrium chart on chloride solution” and shows the different ways that chlorine exists in solution. There are three phases of of solution- CI2 (causing a pungent Chlorine smell and rust), HOCL (effective disinfectant) and OCL (ineffective disinfectant) these phases are shown together with the composition changes that occurs according to pH value.
If pH is 4.0 to 7.0 large amounts of HOCL will be formed. Since it is proven that the main disinfecting agent in chlorine solution is HOCL this state can be used effectively where the concentration of chlorine is from a tiny 10-30 ppm.
On the other hand, sodium hypochlorite solution (Bleach) contains only around 5% of hypochlorous acid; therefore, a very high concentration of chlorine of 1000 to 2000 ppm must be used to achieve the same killing power.

At SpraySafe here in NZ we use EU-certified electrolysis equipment to generate our HOCl water products. The effective chlorine concentration and pH value of our HOCl water can be finely adjusted depending on application.
Safety
HOCl is safe for humans, key benefits are that it can be used on sensitive skin and in conjunction with food, its sterilisation effect is strong, and the method of generation is environmentally friendly and the resulting product has a long shelf life, high stability and is very safe. HOCl can be safely sprayed around humans to sterilise the air unlike other strongly acidic or alkaline electrolytic sterilising water technologies that cannot be safely used for air spray disinfection.
Advantages of mild acid hypochlorous acid water
1. It contains very low concentration of chlorine and is nearly odourless and has no negative impact on skin.
2. It is effective killing microorganisms and spores.
3. It is very gentle on the environment to humans and animals.
4. Wide range of applications, skincare, food preparation, agriculture, medical, personal Hygiene, etc
5. Does not contain any toxic substances such as chloroform, cholic acid, bromic acid.
Proof
In NZ our products are tested and certified by Eurofins and approved for use by MPI
