Can plasticizers from baby products cross the placenta and harm fetal development?

What's actually in it

Plasticizers are chemicals added to plastic to make it soft and bendy. They're in vinyl toys, teething rings, crib mattress covers, changing pads, and food packaging. When older plasticizers like DEHP were restricted in baby products, manufacturers switched to "alternative" plasticizers like DINCH, DEHT, and ATBC. These newer chemicals are less studied, but they're now everywhere.

Pregnant women absorb plasticizers through skin contact, food, and dust. Whatever enters the mother's bloodstream can potentially reach the baby through the placenta.

What the research says

A 2026 review in Reprod Toxicol examined what happens when alternative plasticizers reach the placenta. The researchers gathered evidence from multiple studies testing these newer chemicals on placental tissue.

The findings showed that several alternative plasticizers can cross the placental barrier. Once there, they caused toxic effects including inflammation, oxidative stress, and disrupted hormone signaling in placental cells. A damaged placenta can't deliver nutrients and oxygen to the baby properly.

Some of the replacement chemicals were just as harmful to placental cells as the older plasticizers they replaced. The "safer alternative" label didn't hold up under lab testing.

The review noted a big gap: most of these chemicals were approved based on general toxicity tests, not on how they affect the placenta specifically. Pregnant women got little real protection from the switch.

Choosing products made from natural rubber, silicone, or uncoated fabrics instead of soft vinyl is one way to reduce plasticizer exposure during pregnancy.
