Popular children’s slime toys could pose a health risk, a consumer watchdog has warned. 

Which? carried out an investigation into the crazy which is sweeping playgrounds across the country and has led to millions of YouTube views as well as Instagram hashtags. 

The consumer watchdog tested 11 different slime products for the chemical - boron. 

Exposure to excessive levels of the element can cause irritation, diarrhoea, vomiting and cramps in the short term.

According to the European Commission, exposure to very high levels of boron may also impair fertility and could cause harm to an unborn child in pregnant women.

Eight out of 11 toy slime products tested exceeded the EU safety limit of 300mg/kg.

The worst product, Toysmith Jupiter Juice, had more than four times the permitted level of boron. This was followed by CCINEE Pink Fluffy Slime, which contains 1000mg/kg, and Cosoro Dodolu Crystal Slime Magic Clay, which contains 980mg/kg.

All eight products that failed were purchased on Amazon.  Just one product purchased from Amazon, Hulk Green Halloween Slime, met the standard.

Nikki Stopford, Director of Research and Publishing at Which?, said: ‘If you have school-age kids you’re probably very well aware of the latest slime craze sweeping the playgrounds.

‘Kids love it. Parents buying slime for their children should have peace of mind that these toys are safe, so they will be shocked to find that the health of their children could be put at risk by these slimes.

‘There must be fundamental changes to the product safety system.

‘Manufacturers must stop making unsafe products and the Government and retailers simply have to do a far better job of getting anything identified as a risk off the shelves and out of people’s homes.’

Following the results, Which? is advising parents to approach all slime with caution, as many slimes have minimal safety labelling or information on ingredients.  

Some of the slimes Which? tested even self-certified the packaging with a CE mark, suggesting the product is safe, despite the fact that the boron levels were too high when they were tested.

However, two high street retailers, The Works and Smyths, both sell slime that was found to be within the safety limit when tested.

Although Amazon has now removed the potentially unsafe products from sale, the results raise concerns about the safety of some products sold through online platforms.

Producing ‘homemade’ slime is also a popular alternative, but parents should be careful when considering this option too.

This is because some ingredients listed for slime (such as some contact lens solutions) contain borax, and often slime recipes don’t list the quantities that need to be added.
