Global Regulatory Dynamics of PFHxS

Perfluorohexane sulfonic acid (PFHxS) is a highly surface-active perfluorinated compound with chemical properties similar to perfluorooctane sulfonic acid (PFOS). Following the ban on PFOS by the Stockholm Convention in 2009, PFHxS has been widely used as a substitute in various products. However, PFHxS is persistent in the environment, capable of long-range transport, and may cause developmental toxicity, neurotoxicity, hepatotoxicity, and reproductive toxicity. At the 10th Conference of the Parties to the Stockholm Convention (SC COP-10), PFHxS, its salts, and related compounds were listed in Annex A of the Convention for elimination, with no exemptions allowed.
