2-Propenoic acid, 2-[[(heptadecafluorooctyl)sulfonyl]methylamino]ethyl ester, polymer with 2-[methyl[(nonafluorobutyl)sulfonyl]amino]ethyl 2-propenoate, 2-[methyl[(pentadecafluoroheptyl)sulfonyl]amino]ethyl 2-propenoate, 2-[methyl[(tridecafluorohexyl)sulfonyl]amino]ethyl 2-propenoate, 2-[methyl[(undecafluoropentyl)sulfonyl]amino]ethyl 2-propenoate and α-(1-oxo-2-propenyl)-ω-methoxypoly(oxy-1,2-ethanediyl)

Stain‑, water‑, and oil‑repellent treatments for textiles, carpets, upholstery, leather, paper/packaging, and some industrial coatings [2].

Indoor dust from treated items; skin contact with treated fabrics; drinking water or food contaminated by PFAS; workplace air and surfaces during manufacturing or application [1][2].

PFAS are very persistent; some breakdown products build up in people and are linked to immune effects, higher cholesterol, liver changes, developmental effects, and certain cancers (e.g., PFOA and kidney/testicular) [1][3][4].

Workers handling PFAS; people near production sites or contaminated water; pregnant people, infants, and children; households with many stain‑resistant goods [1][2].

Choose PFAS‑free/untreated products; limit aftermarket “waterproofing” sprays; reduce dust with HEPA vacuuming and wet mopping; check water reports and use certified filters (activated carbon, ion‑exchange, or reverse osmosis) that reduce PFAS [1][2][5].
