Korea Finds Banned Chemicals in Popular Squishy Toys; 8 Products Unsafe

South Korea’s Consumer Agency tested 15 tactile toys sold online and found serious safety violations. All 8 wax puff balls contained banned preservatives that cause skin and eye irritation. One squishy toy had phthalate plasticizers at 6.6 times the allowed limit. The products bypass children’s safety rules because they are labeled for ages 14 and up. Burn injuries from microwaving these toys were reported in April and May 2026.

What chemicals were found in the toys

The Korea Consumer Agency tested 8 wax puff balls and 7 squishy toys. All 8 wax puff balls contained methylisothiazolinone and methylchloroisothiazolinone, preservatives banned under Korea’s toy safety standard. Both chemicals cause allergic skin reactions and eye irritation. One wax puff ball also exceeded the boron limit by 1.3 times. One squishy toy contained phthalate plasticizers at 6.6 times the allowed limit. Phthalates are endocrine disruptors that can damage the liver and kidneys.

Microwave heating poses burn risk

When heated in a microwave, 4 of the 7 squishy toys burst within 25 seconds to 2 minutes 30 seconds. Burn injuries from this were reported in April and May 2026. The products tested include brands called Wakppuball and Mallang-i, which are popular online. Consumers should never put these toys in a microwave.

Why these unsafe products avoid regulation

Fourteen of the 15 products are labeled for ages 14 and up, which exempts them from Korea’s children’s product safety law. This labeling allows manufacturers to sidestep stricter safety requirements that apply to toys for younger children. The Korea Consumer Agency advises buyers to check for the KC safety mark before purchasing any squishy toy or wax puff ball. Without this mark, the product has not passed Korea’s safety tests.

What consumers should do now

If you own any of these squishy toys or wax puff balls, do not microwave them and avoid prolonged skin contact. Check product packaging for the KC safety mark, which indicates the toy meets Korea’s safety standards. Report any adverse reactions such as skin irritation or eye problems to the Korea Consumer Agency. Consider disposing of unmarked products and purchasing only toys with verified safety certification.

Final Thoughts

Korea’s discovery of banned chemicals in popular squishy toys highlights a gap in online product safety enforcement. Consumers should verify the KC safety mark before buying and never microwave these toys. The incident underscores the need for stricter age-labeling rules to close loopholes in toy safety regulations.
