What to do now
The problem with Ninja Slime is chemical: it contains something that should not be there at that level.
- Stop using it, and take it off children straight away.
- Wash your hands and any skin that has been in contact with it.
- The marketplace has removed the listing. Contact the seller through your order history to ask for a refund.
- If you cannot reach the seller, Trading Standards can be told through Citizens Advice.
Why it matters. Limits on substances such as lead, cadmium, phthalates and formaldehyde exist because of their effects on health over time. Children are more exposed because they chew and handle products.
If someone has been hurt
Look out for
- skin redness, itching or a rash where it touched
Get help urgently
- if a child has chewed or swallowed part of it and is unwell, contact NHS 111 or your GP
This is general information based on NHS public guidance, not medical advice. In an emergency call 999. For urgent advice use NHS 111 (NHS 24 on 111 in Scotland) or, in Northern Ireland, your GP or out-of-hours service.
