Can emerging endocrine disruptors in personal care products affect thyroid hormones during pregnancy?
Yes. A 2025 study found associations between emerging endocrine-disrupting chemicals from personal care products and disrupted thyroid hormone levels in pregnant women.
What's actually in it
Personal care products like shampoo, lotion, and cosmetics contain emerging endocrine-disrupting chemicals including UV filters, parabens, and newer preservatives. During pregnancy, thyroid hormones are critical for fetal brain development. Any disruption can affect the baby's neurological outcomes.
What the research says
A 2025 study in Environ Res measured emerging EDC levels and thyroid hormone biomarkers in pregnant women. Several chemicals showed associations with disrupted thyroid hormone balance, which could affect fetal brain development.
