Overview
- In a UBA analysis, MnHexP appeared in 238 of 259 urine samples from 6–17-year-olds (92%), with two results above the 60 µg/L assessment value at 83 and 107 µg/L.
- Samples were collected between April and July 2025 as part of biomonitoring of children and adolescents.
- MnHexP is a breakdown product of Di‑n‑hexyl phthalate (DnHexP), a reproduction‑toxic plasticizer that is not authorized in the EU.
- The agency attributes the exposure to DnHexP impurities formed during production of the sunscreen UV filter DHHB.
- EU rules will tighten maximum allowed DnHexP impurities in DHHB‑containing sunscreens from January 2027, and UBA President Dirk Messner stresses eliminating avoidable sources while maintaining sunscreen use to reduce skin cancer risk.
