Hypochlorous acid has many uses but there are different regulations in different countries.
Not only is it a revolutionary skin antiseptic & disinfectant product, it can also be used to sanitise hard & soft surfaces (including in food prep and eating areas E.g. Chopping boards & High chairs.)
NatraSan and our manufacturing partner ensure all testing and regulations are always up to date and have been approved as part of the EU Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) & UK HSE for uses PT1-5:
PT1: Human hygiene.
Products in this group are biocidal products used for human hygiene purposes, applied on or in contact with human skin or scalps for the primary purpose of disinfecting the skin or scalp.
PT2: Disinfectants and algaecides not intended for direct application to humans or animals.
Used for the disinfection of surfaces, materials, equipment and furniture which are not used for direct contact with food or feeding stuffs.
PT3: Veterinary hygiene.
Used for veterinary hygiene purposes such as disinfectants, disinfecting soaps, oral or corporal hygiene products or with anti-microbial function. Used to disinfect the materials and surfaces associated with the housing or transportation of animals.
PT4: Food and feed area.
Used for the disinfection of equipment, containers, consumption utensils, surfaces or pipework associated with the production, transport, storage or consumption of food or feed (including drinking water) for humans and animals.
PT5: Drinking water.
Used for the disinfection of drinking water for both humans and animals.
The Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) concerns the placing on the market and use of biocidal products, which are used to protect humans, animals, materials or articles against harmful organisms like pests or bacteria, by the action of the active substances contained in the biocidal product. This regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans, animals and the environment.
All biocidal products require an authorisation and the active substances contained in that biocidal product must be approved to be legally on sale.
As of 29th June 2021, in compliance with the specified timescale, NatraSan’s manufacturing partner has filed its UK BPR Active Substance Dossiers with the HSE and are therefore also a legal manufacturer and supplier of hypochlorous acid for the UK market.
Our products have been independently laboratory-tested and proven to be effective against a wide range of microorganisms and comply with:
BS EN 1276 – Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas.

BS EN 14204 – Quantitative suspension test for the evaluation of mycobactericidal activity of chemical disinfectants for instruments used in the veterinary area.
BS EN 13697 – Quantitative non-porous surface test for the evaluation of bactericidal and/or fungicidal activity of chemical disinfectants used in food, industrial, domestic and institutional areas.
BS EN 14476 – Viricidal quantitative suspension test for chemical disinfectants and antiseptics used in human medicine.
BS EN 13727 – Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants for instruments used in the medical area.
BS EN 1650 – Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas.
BS EN 1500 – This European Standard specifies a test method simulating practical conditions for establishing whether a product for hygienic handrub reduces the release of transient microbial flora on hands when rubbed onto the artificially contaminated hands of volunteers.
NatraSan is a multi-use antiseptic, disinfectant and surface sanitiser. It utilises hypochlorous acid technology to make it more powerful and safer than alcohol and bleach alternatives.
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.
Hypochlorous acid effectively kills bacteria, viruses, yeasts, fungus, moulds and spores.
If you have a group of 1 million bacteria. A disinfectant that would kill 99.9% would leave 1,000 bacteria still alive. These bacteria can re-populate to the original size in just a few hours.
With a product that is proven to kill 99.9999% on contact, it will leave 0-1 bacteria alive.
NatraSan Hypochlorous technology is suitable for a wide variety uses including:
- Skin disinfectant and antiseptic
- Surface disinfectant
- Odour Eliminator
NatraSan Hypochlorous is a powerful anti-bacterial, anti-viral, anti-fungal.
The SARS-CoV-2 virus is a betacoronavirus. These types of virus are generally considered to have a low resistance to effective disinfection products.
Our hypochlorous technology (HOCl) has been tested successfully in every case against several types of coronavirus and has been independently tested in UK laboratories to the following European standard EN 14476 (Quantitative suspension test for the evaluation of viricidal activity in the medical area). This test is the benchmark for effectiveness against Coronaviruses.
Since the 2020 pandemic many products have come on the market from nowhere, describing themselves as “hypochlorous acid” and being marketed in many cases by companies that have only been incorporated since the start of the pandemic.
We have laboratory tested a range of these products and in most instances they are not hypochlorous at all – they are sodium hypochlorite (bleach) with a pH of around 8.5. Others described as hypochlorous are a very weak solution at an ineffective concentration of around 25ppm. Yet others were rocket fuel mixtures of hypochlorous and bleach at up to 5000ppm that we wouldn’t put anywhere near our skin. Many of these products claim to be compliant with UK and EU biocidal products regulations but on closer inspection they do not have the individual EU registration that the law demands. Many we looked at didn’t have the most basic information on the label as required by law. Some didn’t even have an expiry date and most only had a shelf life of two to three months. Our advice is to please be careful of what you buy.
The Hypochlorous acid active ingredient in all our NatraSan products is supplied by our technology partners who are the only company who have had their active substance dossiers assessed and approved by the European Chemicals Agency including for human use. It is for this reason that we are trusted to supply the many healthcare and other blue-chip companies we sell to around the world in this crisis.
The pH of all NatraSan Hypochlorous products is neutral at pH 7.2. This means it won’t sting, is non-irritating and non-sensitising.
NatraSan’s Hypochlorous acid has a strength of 150ppm free available chlorine.
NatraSan contains 0.015% hypochlorous acid. The ideal concentration to achieve the products efficacy against pathogens.
Our products need to be protected from UV rays to ensure continued stability. Therefore, all our packaging is UV protected to a very high standard.
Always be very wary about products that claim to be Hypochlorous that are packaged in white or clear bottles.
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.
The answer is NO, the HOCl is a powerful disinfectant yet perfectly gentle and you do not require PPE when using this as a disinfectant or sanitising.
HOCl works much quicker than any disinfectant product you can buy from the supermarket. Typically, at least 5 times faster, working in seconds not minutes, and it kills more germs (including viruses), killing up to 99.9999%.
All our Hypochlorous products will have a use by date to guide you, typically this will be around a year at purchase.
The term ‘acid’ may seem scary, but Hypochlorous Acid (HOCl) is a weak acid and oxidizing agent. It is produced using only water and salt that is passed through a digitalised process of electricity called electrolysis. HOCl is a gentle disinfectant and perfectly safe to use around children or even babies!
NatraSan Hypochlorous acid technology is made in the UK by our partner Aqualution. They are the world leader in Hypochlorous technology and hold the European documentation for its manufacture.
250ml – Turn lock mechanism at top of trigger neck.
500ml – Twist nozzle to spray or jet.
We do not recommend using the product after the expiry date as the solution will not be effective in killing 99.9999% of germs.
NatraSan should not be diluted.
The products utilise the same revolutionary hypochlorous technology, it is just different sizes and delivery systems for the intended use.
The smell is produced naturally by the hypochlorous present and is completely safe, harmless, and gentle. Whilst hypochlorous is far removed from chlorine, it is a member of the chlorine family, albeit one that is produced naturally in all mammalian, avian, and reptilian bodies to kill pathogens. This gives it a slight chlorine odour.
