EU – Proposed Restriction of Undecafluorohexanoic acid (PFHxA)

Germany has submitted a proposal to restrict Undecafluorohexanoic acid (PFHxA), its salts and related substances in the EU.  The proposed restriction includes substances in article based at concentration limits of

  • the sum of PFHxA and its salts at a concentration equal to or above 25 ppb and
  • the sum of PFHxA- related substances equal to or above 1000ppb.

Undecafluorohexanoic acid (PFHxA), its salts and related substances are defined in the proposal as:

(a) Any PFHxA-related substance (including its salts and polymers) having a linear or branched perfluoropenty group with the formula C5F11- directly attached to another carbon atom;
