GSI’s Hassan Javed and Graham K. Ansell, together with co-authors Frank Adamsky, Marco Malvasi, Paige K. Mulvaney, Pier Antonio Guarda, Robert H. Moffett, Simone Genna, Steve Johnston and Xian Liang, have published a study titled “A Critical Review of the Application of Polymer of Low Concern and Regulatory Criteria to Perfluoropolyethers” in Journal of Fluorine Chemistry.
The paper examines perfluoropolyethers (PFPEs), a class of polymeric PFAS widely used as lubricants in aerospace, healthcare, automotive, and other sectors, and evaluates them against Polymers of Low Concern (PLC) criteria. The study finds that PFPEs, owing to their high stability, negligible bioaccumulation, and distinct physicochemical characteristics, pose minimal risk to human health and the environment. The authors emphasize that PFPEs should be evaluated as a separate class for regulatory purposes, distinct from non-polymeric PFAS.
