Chemicals firm 3M has filed a petition to this effect with the federal Food and Drug Administration (FDA). This was published on 29 April in the Federal Register.
The substances are ammonium bis (N-ethyl-2- perfluoroalkylsulfonamido ethyl) phosphates, and perfluoroalkyl acrylate copolymer containing 35%-40% by weight of fluorine. Both were previously used as water- and oil-repellent coatings for paper and paperboard food contact packaging.
The request to remove 3M’s permission under Part 176 of Title 21 of the Code of Federal Regulations (CFR 21.176) has been taken by 3M because it has stopped using both. It is part of a wider industry-led campaign to substitute away from PFAS-based repellents. This has been prompted by ongoing lobbying against such substances – particularly focusing on their presence in packages, like pizza boxes, that contact fatty foods.
