Kids Stuff Crazy Foaming Soap - February 2026

On this week’s Watchdog, Nikki investigates safety concerns surrounding Kids Stuff Crazy Foaming Soap, a mouldable aerosol bath foam marketed for children to play with under adult supervision.

Despite being widely available on the UK high street and in supermarkets, we’ve heard of reports of the product catching fire, where candles or incense are present. We heard of a case of a three-year-old girl who suffered significant burns, after the foam ignited, after an incense stick was burning nearby. There was also an incident where an 11-year-old, in Estonia sustained second-degree burns, in 2023 and a seven-year-old, in the UK, who experienced flash burns in 2025.

We had the foam tested, in a lab and found that it burned for 15 seconds. Cosmetic scientist Colin Sanders raises concerns about its flammable ingredients and suggests it should be reformulated.

Nikki also examines why the product remains on sale in the UK, where it is classified as a cosmetic rather than a toy, unlike in Estonia. Christine Heemskeerk, from the Chartered Institute Trading Standards questions whether stricter toy safety regulations should apply. When we wrote to Kids Stuff, it told us that its Crazy Foaming Soap is classified and regulated in the UK as a cosmetic aerosol, that it complies with all applicable safety and labelling regulations, and that the company is in regular contact with Trading Standards.

Kids Stuff told us that the product carries clear and prominent warnings, including that it is an extremely flammable aerosol, must not be used near naked flames or ignition sources, and should only be used under adult supervision. It went on to say that it has also introduced additional on-pack safety measures, including cap stickers, to further reinforce safe use.

It said it takes product safety extremely seriously, and it is already progressing an updated formulation of Crazy Foaming Soap, which it expects to release later this year.

Finally, Kids Stuff told us that bath time products should always be used in line with pack instructions and under adult supervision, and that children should never be left unattended in the bath or in environments where open flames or heated instruments are present.

The Department for Business and Trade, which oversees the Office for Product Safety and Standards, told us that it’s deeply concerned about the reports Watchdog highlighted, which is why it has launched a full investigation.

It told us that it’s testing similar products on the market to ensure they do not pose a risk to children and the wider public, and that it will demand manufacturers act if necessary.

We also wrote to West Yorkshire Trading Standards, which declined to comment.
