Frequently Asked Questions

NatraSan, a revolutionary cleansing spray that leverages the power of hypochlorous acid, a naturally occurring substance produced by the human immune system to combat infections. This advanced technology ensures your skin is thoroughly purified and cleansed, without any harsh chemicals.

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.

An amazing eco product, it is readily biodegradable dissipating to salt & water.

Hypochlorous acid effectively kills bacteria, viruses, yeasts, fungus, moulds and spores.

Natrasan Hypochlorous Spray offers you an advanced cleansing solution for face and body. Being Alcohol-free it is perfect for all members of the family from ones with sensitive skin to the littlest of little ones.

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.

HOCl gives the benefit of protecting you on contact, being able to kill germs & pathogens immediately compared to Alcohol-based disinfectants that can take up to 15 minutes.

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!

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 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.
