The glibberige play slime is very popular with children. But the colourful fun of playing can be harmful to health. Stiftung Warentest has tested five slime products.

Boric acid is responsible for the slimy consistency of the play slime. In larger concentrations, however, it has a harmful effect on the little ones. The products tested were within a price range of 11 to 25 euros.

Stiftung Warentest investigates play slime

In the laboratories of the consumer protector, the light green version was tested, as it was included in each of the sets purchased. The frightening result: The five play slime products release so much boric acid that they would not even be suitable for sale.

In most cases, boric acid is absorbed through the skin. In the case of children, ingestion through the mouth or swallowing the mucus cannot be ruled out. Packaging, for example in the form of beverage cans or straws, encourages children to assume that the product is also suitable for the mouth. Taking too high a dose of boric acid can cause irritation, diarrhoea, vomiting and cramps in the body.

Same test result with partner organizations

The Italian, Spanish and British partner organisations of Stiftung Warentest have discovered play slime products that also exceed the boric acid limit. This was the case for 16 of the 33 slimes tested.

Limit value for children’s toys

The European Chemicals Agency (ECHA) has classified boric acid as toxic to reproduction. In addition, limit values apply to children’s toys in the EU. For example, liquid or adhesive toy materials must not release more than 300 milligrams of boric acid per kilogram. The EU limit values are clearly exceeded by the five slime products tested. Three of the tested slime products even release three times as much boric acid.

Online platform removes slimes from the marketplace

The online platform, on which Stiftung Warentest acquired the so-called slimes, immediately took them down from the marketplace after the confrontation with the results. Consumer protectors were told by the online platform: “The corresponding products are no longer available”.

Stiftung Warentest recommends that consumers “do not expose children to the muddy side of boron compounds”. The new problem is actually already a well-known one, because 2004 warned the Federal Institute for Risk Assessment of boric acid-containing Hüpfknete . Before the Slimes already 1995 was warned. As the current results of the Stiftung Warentest show, little has changed.
