Poly(oxy-1,2-ethanediyl), α-[2-[ethyl[(heptadecafluorooctyl)sulfonyl]amino]ethyl]-ω-hydroxy-

Made for textile and paper treatments, coatings, and other water/oil‑repellent uses; can form from breakdown of treated products and industrial wastes [1].

Drinking water, indoor dust, contact with treated fabrics/paper, food contact materials, and workplace air in manufacturing or application settings [1][2].

Very persistent and can transform to PFOS; PFOS is associated with immune effects and altered cholesterol, among other outcomes [1][3]. EPA set very low drinking water limits for PFOS due to health risks [2]. PFOA (a related PFAS) is classified carcinogenic to humans; PFOS is possibly carcinogenic [4].

Workers in textile/paper finishing, metal plating, and firefighting; people near PFAS production or AFFF use sites; pregnant people, infants, and young children [1][2].

Use certified PFAS-reducing filters (activated carbon or reverse osmosis); check local water reports; limit use of stain‑resistant sprays or treatments; damp‑dust and vacuum with HEPA; follow workplace controls and PPE [1][2].
