On August 4rd 2021, the European Union published a new restriction for certain perfluorinated substances.
The restriction covers Perfluorocarboxylic acids containing 9 to 14 carbon atoms in the chain as well as related substances. Limits are 25 ppb and 260 ppb for related substances. Regulation will come into force 25 February 2023.
Background
On August 4th 2021, the European Commission published Regulation (EU) 2021/1297 to amend the restrictions in REACH Annex XVII. This Regulation restricts Perfluorocarboxylic acids containing 9 to 14 carbon atoms in the chain (C9-C14 PFCAs), and will apply from 25 February 2023. Apart of other applications, long chained polyfluorinated substances might be used to provide water or stain resistant finishing.
For the following substances, a limit of 25 ppb is set:
• Linear and branched perfluorocarboxylic acids of the formula CnF2n+1-C(=O)OH where n=8, 9, 10, 11, 12, or 13 (C9-C14 PFCAs), including their salts, and any combinations thereof;
For the following substances, a limit of 260 ppb is set:
• Any C9-C14 PFCA-related substance having a perfluoro group with the formula CnF2n+1- directly attached to another carbon atom, where n = 8, 9, 10,11, 12, or 13, including their salts and any combinations thereof;
• Any C9-C14 PFCA-related substance having a perfluoro group with the formula CnF2n+1- that it is not directly attached to another carbon atom, where n = 9, 10, 11, 12, 13 or 14 as one of the structural elements, including their salts and any combinations thereof.
Substances are based on
PFNA - Perfluorononan-1-oic acid (C9-PFCA, CAS 375-95-1)
PFDA - Nonadecafluorodecanoic acid (C10-PFCA, CAS 335-76-2)
PFUnDA - Henicosafluoroundecanoic acid (C11-PFCA, CAS 2058-94-8)
PFDoDA - Tricosafluorododecanoic acid (C12-PFCA, CAS 307-55-1)
PFTrDA - Pentacosafluorotridecanoic acid (C13-PFCA, CAS 72629-94-8)
PFTDA - Heptacosafluorotetradecanoic acid (C14-PFCA, CAS 376-06-7)
which are already listed as substance of very high concern (SVHC).
