South Korea flags hazardous substances and burn risks in online sensory toys
The Korea Consumer Agency tested 15 online sensory toys against children’s toy-safety limits, finding restricted preservatives in eight wax balls and excessive phthalate in one squishy. Microwave tests also identified rupture and burn risks.
What the primary source says
The Korea Consumer Agency issued a consumer safety warning on 23 September 2026 after testing 15 sensory toys sold online: eight wax-ball products and seven squishies.
Fourteen were labelled for users aged 14 and over. The agency therefore used children’s toy-safety limits as assessment benchmarks; its results should not be read as a finding that every tested product was legally subject to those rules.
All eight wax balls contained methylisothiazolinone and methylchloroisothiazolinone, preservatives prohibited under the benchmark toy criteria. One wax ball released boron at 1.3 times the limit. One of the seven squishies contained phthalate plasticiser at 6.6 times the limit. The report’s appendix identifies the tested products and sellers; it does not provide a blanket recall or identify every sensory toy on sale as hazardous.
In separate 1,000W microwave tests, four squishies ruptured within 25 seconds to 2 minutes 30 seconds. All seven reached surface temperatures of 70.0°C to 171.2°C. Heating these products can cause burns and is not their intended use.
The agency also identified incomplete product, importer, age and warning information on some listings. It recommended improvements to 17 businesses; 12 had completed or agreed to corrective action at publication.
The agency advises consumers not to microwave these products, to keep products labelled for ages 14 and over away from younger children, and to check appropriate South Korean KC marking and registration details when buying children’s products. This is a South Korean investigation and corrective-action notice, not evidence of a UK recall or regulatory finding.

Why it matters
The useful distinction
Online novelty toys can carry chemical, labelling and heat-related risks even when marketed for older users; children may still use them.
