Chemical UV filter that accumulates in the body faster than it is eliminated. The EU has lowered its maximum allowed concentration due to hormonal disruption concerns.

What the research flags

  • Endocrine disruption — disrupts estrogen, androgen, and progesterone [inference]
  • Bioaccumulation — detected in human blood and breast milk
  • EU reduced max concentration from 10% to 1.4% (2021)
  • Enhances skin absorption of other chemicals

Regulatory
EU restricted from 10% → 0.5% (SCCS 2020 opinion: unsafe at old limit)
