General
What is NatraSan?

NatraSan is a multi-use antiseptic and disinfectant. It is powerfully antibacterial, antiviral and antifungal. NatraSan has no hazardous safety profile and is so gentle it can be used on human skin from birth. NatraSan kills 99.9999% of pathogens and has a very low contact time, meaning it will kill germs in seconds. It is supplied in a number of packaging formats and is supplied ready to use. The active ingredient is hypochlorous acid, See below.

So what is hypochlorous?

Hypochlorous is a weak acid produced in human and animal immune systems. It is the substance the cells in our bodies use to fight infections and kill invading pathogens.

Hypochlorous is one of the most effective known biocides capable of killing 99.9999% of all pathogens. It is also readily biodegradable and leaves no chemical trace. It is the perfect antiseptic to use on your skin.

What is the difference between NatraSan and hypochlorite based products?

Various products using the terminology “hypochlorous” are actually hypochlorite based.

Hypochlorite based products contain a mixture of chlorine, hypochlorous acid and sodium hypochlorite at an acidic pH. They are also unstable and can decay rapidly.

Chlorine and sodium hypochlorite are toxic, corrosive and can damage fabrics.

What is the difference between NatraSan and other hypochlorous acid based products?

Since the start of the 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.

What are the European Biocidal Products Regulations?

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 and the environment.

All biocidal products require an authorisation and the active substances contained in that biocidal product must be approved.

Why haven’t I seen this before?

Hypochlorous was discovered in the 19th century by a British scientist. It was actually manufactured for the first time in the 1960’s.

There was always a problem however in that no one was able to make a stable version that had a shelf life so it could be packaged. The only organisations that could take advantage of this incredible product were large scale industrial and agricultural operations such as dairy and poultry units, where they produced non-stable hypochlorous onsite for immediate use.

Our team of scientists have worked out how to stabilise the active ingredient so we can now make it available to everyone.

What is the pH of NatraSan?

The pH of NatraSan is neutral at pH7. This means it won’t sting.

What is the PPM of NatraSan?

The hypochlorous acid in NatraSan has a strength of 150ppm free available chlorine.

What percentage of hypochlorous acid does NatraSan contain?

NatraSan contains 0.015% hypochlorous acid. The ideal concentration to achieve the products efficacy against pathogens.

How should NatraSan be stored.

NatraSan should be stored out of direct sunlight, other than that there are no specific storage requirements.

Can NatraSan be transferred to other containers?

We don’t recommend this as NatraSan needs to be protected from UV rays. All our packaging is UV protected to a very high standard.

Response regarding the effectiveness of NatraSan against the SARS-CoV-2 virus and COVID-19.

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.

We have supplied hundreds of thousands of litres of our hypochlorous technology to healthcare providers around the world to help them in their battle against this virus.

Remember NatraSan is alcohol free, skin friendly, non-sting and much faster acting than conventional alcohol-based sanitisers. With this virus you need to kill it fast.

Keep safe.
