A rigorous round of testing by the consumer product review title Which? has uncovered that less than 30 per cent of slime currently on the market meets the EU safety standards.
The site is now warning parents to approach the popular children’s product with caution after tests found that some contain more than four times the safety limit levels of the chemical boron.
Exposure to excessive levels of boron could cause irritation, diarrhoea, vomiting and cramps in the short term.
Eight out of the 11 children’s slimes tested were found to exceed the limits of the chemical that has been linked to impaired fertility or harm to unborn children in pregnant women when found in high dosages.
All eight were available to purchase via Amazon but have since been removed from the online trading platform. Which? is now calling for all potentially unsafe children’s slimes to be removed from sale and for the government to act to safeguard children’s safety when it comes to slime.
Amazon released the following statement:
‘All marketplace sellers must follow our selling guidelines and those who don’t will be subject to action, including potential removal of their account. The products in question are no longer available.’
The permitted level for boron in all children’s toys is 300mg/kg.
Of those tested by Which? the worst was Toysmith Jupiter Juice with 1,400mg/kg, followed by CCINEE Pink Fluffy Slime with 1,000mg/kg and Cosoro Dodolu Crystal Slime Magic Clay with 980mg/kg.
The best of the slimes tested were H Grossmans’ Goopy Slime, Glam Goo Deluxe Pack and Planet Slime Shop’s Hulk Green Halloween Slime.
Boron is found in slime a the compound Borax, used to give it its gelatinous texture.
Which? is urging anyone to have purchased unsafe slime to return the item to Amazon for a full refund or replacement.
Of the results, HGL’s managing director, Martin Grossman said: “I am not surprised by these results, there are lots of unsafe products out there, we make sure that our slime and putty is of a high standard, good quality and good play value.”
All slime products deemed safe were purchased via High Street stores.
