Battery revolution: How the EU is forcing Nintendo, Apple and co. to rethink their approach

Why kinetic sand and rubber animals are being recalled across Europe, how serious the danger really is, and what you need to do.
«Asbestos in children’s playrooms» is a headline that has alarmed many parents in recent weeks. Unfortunately, the products at the centre of the current reports are found in countless households: kinetic sand and rubber animals filled with it. The discovery of carcinogenic asbestos fibres in these kinds of toys across Europe has led to immediate product recalls. But how does this hazardous substance end up in children’s toys in the first place? And how do experts assess the actual health risk to children who’ve already played with it?
When people think of sand, they usually picture the classic quartz sand found on playgrounds. But this colourful, mouldable indoor sand – often called «magic sand» – is different. To achieve its doughy, almost liquid consistency, it’s usually made of extremely fine rock powder coated with a special binding agent. Crushed marble or limestone is also often used in production. And this is exactly where, deep within the rock, the problem at hand begins.
When you hear the word «asbestos», the first things that probably come to mind are textured wallpaper, old roofing sheets, or insulation materials from the 70s. However, asbestos isn’t an artificial toxin, but a naturally occurring, fibrous silicate mineral.
Much of the sand currently in use comes from Asian mining areas, particularly those in China. Although marble and asbestos minerals (such as tremolite or chrysotile) are often found in the same rock layers worldwide. However, the mining of these rocks is subject to strict controls in Europe, whereas regulations in China are significantly less stringent. If the marble is quarried there and ground into a fine powder, asbestos fibres can end up in the final product without being noticed. To make matters worse, asbestos is still used industrially in China, and in some cases, products aren’t required to be labelled as containing asbestos until their asbestos content reaches five per cent.
When playing with the sand, kneading, or sifting it, microscopic asbestos fibres can become airborne and enter the respiratory tract. One thing’s certain: asbestos is highly carcinogenic. The fibres can become embedded in lung tissue and cause serious illnesses such as asbestosis or tumours – even after decades.
At the moment, it’s not scientifically possible to reliably quantify the actual risk posed by play sand in individual cases. Although the Belgian research institute Sciensano initially classified the health risk in the samples they examined as «negligible», the German Federal Institute for Risk Assessment (BfR) disagrees with a blanket all-clear. According to the BfR, there is simply a lack of reliable data to conclusively assess the risk. It’s still unclear how much the asbestos concentrations vary between individual production batches and how many fibres are actually released into the air while playing. However, since there’s no safe level of asbestos exposure, caution is essential.
Asbestos has been strictly banned in the EU and Switzerland since the 1990s. Legally speaking, there’s therefore no «safe» threshold. If even a single fibre’s found, a product is considered a hazardous asbestos-containing material.
The German consumer organisation «Stiftung Warentest» recently tested 22 products in a lab. They detected asbestos in ten of them. Among the items affected are products from Asian online retailers, but established retailers also had to take action. Smyths Toys, for example, recalled digging sets such as «Dig it out Dinosaur Eggs», and the manufacturer Trendhaus issued a warning about sand-filled «Stretcher Toys».
While large parts of the market for moulding sand are affected in Germany, the situation in Switzerland is somewhat clearer. The Federal Food Safety and Veterinary Office (BLV) has so far mainly issued warnings about five specific stretcher toys which were immediately recalled. The market leader Spin Master has also publicly clarified that the original sand sold under the brand name Kinetic Sand» is currently asbestos-free and not affected (links in German).
Galaxus also responded immediately by removing the affected products from the store. Since online orders are individual, we were able to notify the affected customers directly via e-mail. We continue to closely monitor the situation through official reporting channels such as Recall Suisse and immediately remove any suspicious items from sale.
Even if you want to play it safe, you don’t have to miss out on the sensory play experience. You can easily make your own mouldable magic sand using completely safe household ingredients. A tried-and-true recipe in German consists of eight cups of all-purpose flour and one cup of cooking oil. You knead the flour-oil mixture until it reaches the typical, slightly moist, and doughy consistency. With this, it’s guaranteed to be asbestos-free, plus it’s easy on the wallet.
If you have coloured play sand of unknown origin at home or own one of the recalled products, please note the following:
Don’t panic, but take decisive action. Dispose of questionable sand according to the guidelines and switch to homemade or certified alternatives.
