Hand sanitiser gels sold online fail Which? tests

Independent Which? tests have revealed that some hand sanitisers contain a fraction of the alcohol content they claim to, leaving those who buy them unknowingly unprotected from coronavirus – and other bacteria and viruses these products are supposed to kill.

Hand sanitiser with an alcohol content of at least 60% is recommended by the World Health Organisation (WHO) and other experts as the best way to kill any COVID-19 virus particles that may be on your hands when out and about (thorough hand washing with soap is preferable, but not always practical).

We tested 18 hand sanitisers, including branded and own-brand options from major retailers, supermarkets and online marketplaces. Boots, Superdrug, Tesco and Wilko hand gels – and popular listings on Amazon, Ebay and Etsy – were among those tested.

Three hand sanitiser products, all bought from Ebay or Etsy, contained far less alcohol than claimed, and too little to be effective at killing germs.

So, if you’re stocking up on sanitiser, make sure you check our list of the products that passed, below, to ensure you get one that contains enough alcohol to do the job properly.

Hand sanitisers to avoid

Three hand sanitisers, bought from either Ebay or Etsy, did not contain the percentage of alcohol that was claimed on either the packaging or the product listing page.

These products don’t contain enough alcohol to kill germs effectively, and should be avoided:

  • Hansan Antibacterial Hand Sanitiser (bought from Ebay)
  • Klenzy Hand Sanitizing Gel (bought from Ebay)
  • Vaida Makeup ‘Dream Big’ Hand Sanitiser Gel (bought from Etsy)

When the first sample failed our tests, we tested a second sample of each product to check if it was a one-off. But the results for both samples, bought at random, were nearly identical.

The Klenzy hand sanitiser had just 10% alcohol content in total, while the Hansan and Vaida Makeup products had just over 30%. All claimed to contain at least 70% alcohol.

Product Claimed Alcohol content Ethanol content (by weight) Isopropanol content (by weight)
Klenzy 75% 3.2% 6.6%
Hansan 70% Trace 34.6%
Vaida Makeup 70% Trace 32.6%
Results shown are for the sample with the lowest alcohol content, but for all products, both samples returned results within a few percent of each other.

We tested hand sanitiser alcohol content by weight. Manufacturers differ in how they quote alcohol content, using either weight or volume, and many don’t specify what the claim is based on.

By volume, the percentage alcohol content figures for these products would be slightly higher, but would still fall well short of recommended levels – and the claim on the bottle. 

Hand gels removed from sale following Which? tests

We contacted the individual sellers and relevant online marketplaces with our findings.

We did not receive a response from the sellers of the Hansan and Klenzy gels and were unable to find the contact details for the manufacturers of these products.

Ebay told us it had removed both the product listings and that the sellers would no longer be permitted to sell hand sanitiser on its website. 

The Etsy seller of the Vaida Makeup hand sanitiser told us that it had removed the listing and contacted all customers to warn them of the lower alcohol content in the sanitiser and to offer a full refund.

Etsy told us it was ‘pleased’ the seller had removed the item from sale, stating: ‘We don’t have final control over sellers’ items but do ask they act with integrity, as was the case here by them taking action once the issue was brought to their attention.’

We shared our findings with the Office for Product Safety and Standards (OPSS) for further investigation. It told us it has passed them on to the Health and Safety Executive and Trading Standards.

Which hand sanitisers passed the alcohol test?

 

The good news is that the remaining 15 hand sanitisers we tested all had the percentage levels of alcohol that they claimed or higher, and at a level that would be effective against bacteria and viruses.

High street own-brand products from Boots, Superdrug, Tesco, Waitrose and Wilko all passed, as did branded offerings from Milton, Neal’s Yard, Dettol, Carex and Cuticura.

Some of these products may have been hard to get hold of in the early days of the pandemic, but supplies have since stabilised.

At £1.25 for a 200ml bottle, Wilko hand sanitiser is the most affordable option overall, but for a handy pocket-sized pack, Tesco and Waitrose 50ml bottles are also good value (75p / 80p).

High street hand sanitiser results – in full

Product name Claimed alcohol content Ethanol content (by weight)
Milton Antibacterial hand gel, £2.29 / 100ml 80% 86.3%
Neal’s Yard Natural Defence Hand Rub, £5.75 / 40ml 70% 76%
Carex Aloe Vera hand gel, £3.49 / 300ml 70% 71.1%
Waitrose Essential hand gel, 80p / 50ml 62% 66.6%
Wilko Antibacterial hand gel, £1.25 / 200ml 60% 66.1%
Superdrug Aloe Vera hand gel, £1.25 / 100ml 62% 65.9%
Dettol Hand Hygiene Gel, £1.79 / 50ml 63% 65.7%
Tesco Health hand gel, 75p / 50ml 62% 65.6%
Cuticura Original hand gel*, £1.55 / 100ml 57.6% 59.4%

*The Cuticura product states it has 57.6% ethanol by weight, which converts to 66% ethanol by volume and so meets the 60% minimum requirement.

Online hand sanitiser results

The selection of products we tested from Amazon all contained the alcohol they claimed to.

Product name Claimed alcohol content Ethanol content (by weight)
Halo hand gel, £11.99 / 10x 100ml 75% 75.8%
Calypso Anti-bacterial hand gel, £2.99 / 100ml 70% 75.5%
Nilco Home hand sanitiser, £11.99 / 2x 500ml 70% 73.6%
E-Fast Anti-Bacterial Hand Sanitiser Gel, £1.90 / 50ml 70% 71.3%
Oceanfree+ hand sanitiser gel, £4.99 / 3 x60ml 70% 70.6%
Lakeland Cosmetics Moisturising anti-bacterial hand gel, £5.75 / 3x 50ml 70% 70.3%

These products tended to have a slightly higher alcohol content than high street gels, though bear in mind if you have sensitive hands, they may tolerate a lower effective alcohol concentration better.

Note – some of the samples in the tables above also contain small amounts of isopropanol, but the main active ingredient is ethanol.

What are the legal requirements for hand sanitisers in the UK?

In the UK, hand gels should comply with the EU Biocides Regulation 528/2012. They should be able to prove that the product matches the claims, so if a product makes a certain claim, such as it kills 99.9% of bacteria and viruses, then it should fulfill that claim.

While the products we found to fall short of their claims have now been taken down by either the retailer or the individual sellers, it’s worrying that of the few products we picked to test, several were found to be so low on alcohol as to be ineffective at killing germs.

Why is alcohol important in hand sanitiser?

Family using hand sanitiser gel

The alcohol found in hand sanitisers is usually ethanol, isopropanol or a mixture of the two. Alcohol destroys viruses and bacteria by dissolving the outer layer which inactivates them. This is how it kills the COVID-19 virus.

Ethanol is what you get in drinking alcohol, while isopropanol is what’s more commonly known as ‘rubbing alcohol’.

At the right percentage (at least 60% by volume, according to the WHO) both will have the same sanitising effect on bacteria and viruses. However, if the hand sanitiser doesn’t contain a high enough percentage of alcohol, then it won’t be able to kill off the bacteria and viruses on your hands effectively.

Methanol in hand sanitiser

Hand sanitiser has been in high demand this year, and at times very hard to find. But it pays to be cautious about who and where you buy from.

In the US, the FDA has warned about a long list of hand sanitiser brands that were found to contain methanol, which is highly toxic, while in Australia, consumer organisation Choice has also uncovered hand sanitisers with a fraction of the claimed alcohol content.

We didn’t detect methanol in any of the hand sanitiser samples we tested. However, we tested only a few of the many brands available online, and it pays to remain vigilant, as there have been some hand gel products recalled in the UK which were found to contain methanol.

Symptoms of methanol poisoning include headaches, blurred vision, nausea and vomiting, loss of coordination and decreased levels of consciousness.

What about non-alcoholic hand sanitiser?

Alcohol-based hand sanitisers can be irritating and drying for the skin, especially when used more frequently.

There are alcohol-free alternatives, which are gentler on the hands, but knowing which ones work effectively is no simple task.

Alcohol-based sanitisers are recommended for protection against COVID-19 in public health messaging because the evidence for them working at the right concentration is quite clear-cut.

Some common chemicals used in non-alcoholic hand sanitisers have been proven to be effective on surfaces and in suspension tests (in lab conditions), but the evidence isn’t as clear for use on hands.

EN1500 is the standard that products must pass to demonstrate bactericidal efficacy when the product is applied to hands, but there isn’t a test standard like this for enveloped viruses on hands.

Ecohydra, one of the main alcohol-free hand sanitiser manufacturers, is calling for clarity on the matter and for a kitemark standard for non-alcoholic hand sanitisers to be introduced so that consumers can easily see which products have passed tests.

Are you using your hand sanitiser properly?

As well as buying a hand sanitiser you can trust, it’s also important that you store and use your hand sanitiser the right way in order for it to work.

Check out our video guide below to get our top tips on using hand sanitiser effectively to kill germs.

  • Sanitise after touching any surfaces or items that could be contaminated, such as hand rails, doors or your face mask. Reapply if you touch anything after this.
  • Use enough hand sanitiser to cover the full surface area of your hands – not forgetting your wrists and nails.
  • Rub it in for at least 20 to 30 seconds – or most importantly, until your hands are dry.
  • Store away from direct heat and light sources, and don’t leave it open – as these could all impact the quality and efficacy of the product.
