2-Propenoic acid, 2-methyl-, 2-[ethyl[(heptadecafluorooctyl)sulfonyl]amino]ethyl ester, polymer with 2-[ethyl[(nonafluorobutyl)sulfonyl]amino]ethyl-methyl-2-propenoate, 2-[ethyl[(pentadecafluoroheptyl)sulfonyl]amino]ethyl 2-methyl-2-propenoate, 2-[ethyl[(tridecafluorohexyl)sulfonyl]amino]ethyl 2-methyl- 2-propenoate, 2-[ethyl[(undecafluoropentyl)sulfonyl]amino]ethyl 2-methyl-2-propenoate and octadecyl 2-methyl-2-propenoate

Treated carpets, upholstery, outdoor gear, leather, floor/fabric protectors, food‑contact papers, and manufacturing or application sites [1][2].

Breathing indoor dust and air from treated items or sprays; contact with treated fabrics; drinking water near production, use, or disposal; food from grease‑resistant packaging [1][2].

Some breakdown products (e.g., PFOA/PFOS) persist and are associated with developmental effects, immune suppression (reduced vaccine response), higher cholesterol, thyroid effects, and certain cancers; EPA set very low drinking‑water limits for several PFAS; IARC classifies PFOA as carcinogenic to humans [1][2][4][5].

Workers making/applying repellents; people using spray waterproofers in small spaces; pregnant people, infants, and children; communities with PFAS‑contaminated water [1][2][4].

Choose PFAS‑free/no‑fluor stain‑repellent products; skip or limit aftermarket waterproofing sprays (or use non‑fluorinated options with good ventilation); avoid grease‑resistant packaging; HEPA‑vacuum and damp‑dust; wash hands; consider activated carbon or reverse osmosis filtration for drinking water [1][2].
