Are bisphenols in kid toys leaching out when babies chew on them?
Yes. Lab simulations show real bisphenol release into baby saliva from common plastic toys.
What's actually in it
Hard, clear plastic toys are often made from polycarbonate, which contains bisphenol A or its swap-outs BPF and BPS. The bisphenols aren't fully locked into the plastic, so heat, acid, and chewing can pull them loose.
Babies' mouths give all three: warm temperature, mild acid from saliva, and chewing pressure.
What the research says
A 2025 study in Chemosphere tested children's products on the Swiss market by soaking them in fake saliva that mimics what a baby's mouth would do. Several toys released measurable BPA, BPF, and BPS. The dose for a baby chewing all day got close to the European safety threshold.
The team flagged that even "BPA-free" labels weren't safe: the swap chemicals showed up just as often.
Look for natural rubber, untreated wood, or food-grade silicone teethers and chew toys. Skip clear hard plastic items for kids who still mouth everything.
