CTPA Issues Important Call for Interest in Defence of UV Filter DHHB

CTPA announces that on October 7, 2024, German biomonitoring studies found levels of phthalate MnHexP in urine samples from individuals, including kindergarten children. The source of this exposure is not yet clear but may be linked to DnHexP (CAS 84-75-3), a substance banned in cosmetics (Annex II/1559) due to its classification as Repro 1B. Concerns have arisen that trace amounts of DHHB (CAS 302776-68-7), a UV filter permitted in sunscreens (Annex VI/28), could be contributing to this issue.

 German authorities (BfR and UBA) concluded that adverse health effects are unlikely due to the low levels of MnHexP found, which are below the tolerable daily intake (TDI) and health-based assessment value (HBM). DG GROW is planning to consult the SCCS regarding potential health risks associated with the use of DHHB as a UV filter in cosmetic products and to determine the minimum safe level of DnHexP as a technically unavoidable contaminant in DHHB preparations. Companies interested in contributing to the defense of DHHB should contact CTPA at info@ctpa.org.uk by October 16, 2024.
