Researched April 18, 2026

Concerns

  • Potent estrogen mimic — disrupts female and male reproductive development
  • Detected in blood, urine, breast milk, and placental tissue (CDC biomonitoring)
  • "BPA-free" products often use BPS or BPF — similar hormonal disruption profile
  • Linked to PCOS, lower sperm quality, and early puberty onset in research [inference]

Regulatory flags

  • BPA banned in baby bottles (EU 2011, FDA)
  • EFSA tolerable daily intake revised to 0.2 ng/kg/day (2023)
  • California Prop 65 listed (BPA)
  • BPS and BPF may carry similar endocrine-disrupting effects
