HFPO–DA

HFPO-DA (Hexafluoropropylene oxide dimer acid) is a man-made chemical in the PFAS family, used by manufacturers like Chemours as a processing aid (trade name GenX) to create high-performance fluoropolymers, replacing older chemicals like PFOA. While it’s designed to be safer than PFOA, concerns exist about its persistence and potential adverse health effects, including liver damage and developmental issues, prompting health advisories and monitoring in drinking water.
