Do flame retardants in car seats pose risks to infants?
Yes. Peer-reviewed research links exposure to flame retardants used in consumer goods to significant developmental, cognitive, and health risks in children.
What's actually in it
Car seats often contain organophosphate ester flame retardants and brominated flame retardants. These chemicals are added to foam and fabrics to meet flammability standards. They are not chemically bonded to the materials, meaning they easily break down into dust or off-gas into the air your infant breathes.
Because these chemicals are not locked into the product, they accumulate in the environment. Infants are especially vulnerable because they spend significant time in car seats and frequently touch or mouth surfaces covered in these dust particles.
What the research says
The science is clear that these chemicals are linked to long-term health issues. A 2026 study in Environ Pollut found that prenatal exposure to organophosphate esters is associated with impaired child cognition. These impacts on brain development are a major concern for growing infants.
Other research highlights the physical and behavioral toll. A 2026 study in Environ Res linked halogenated flame retardants to thyroid function changes and ADHD-related traits in children. Additionally, a 2026 study in J Expo Sci Environ Epidemiol connected these chemicals in house dust to behavioral outcomes.
The risks extend to physical growth and immune health as well. A 2026 study in Environ Res examined how these flame retardants influence child growth in weight and BMI. Furthermore, a 2026 study in Sci Total Environ identified a clear association between brominated flame retardants and the development of allergies in children.
