Do plastic bath toys release chemicals into warm bathwater?
Yes. Warm water pulls plasticizers and hormone-disrupting chemicals out of soft plastic bath toys. Studies show both original chemicals and their 'safer' replacements leach during normal bath use.
What's in bath toys
Most squeezable bath toys are made from soft PVC (polyvinyl chloride) or similar flexible plastics. To make hard plastic soft enough to squeeze, manufacturers add plasticizers like phthalates. These chemicals aren't bonded to the plastic. They can leach out, especially in warm water.
Bath time creates the perfect conditions for chemical release: warm water, prolonged soaking, and kids who squeeze water in and out of toys and often put them in their mouths.
What the research says
A 2026 study tested bisphenol alternatives used in children's products including bath toys and found that replacement chemicals have endocrine-disrupting effects similar to the original BPA they replaced. Products labeled "BPA-free" still contained hormone-active substances.
Additional 2026 research measured chemical release from children's plastic products under conditions that mimic real use. Warm water significantly increased the rate at which chemicals moved from plastic into the surrounding water. Bath toys that had been used repeatedly released more chemicals than new ones, suggesting the plastic degrades with use.
Safer bath time options
Choose bath toys made from solid natural rubber or silicone instead of soft PVC. Avoid toys with holes that trap water inside, as these also grow bacteria and mold. Replace bath toys regularly rather than keeping them for years. After bath time, dry toys completely and store them outside the tub.
