2-[Butyl[(heptadecafluorooctyl)sulfonyl]amino]ethyl acrylate

Used in surface‑treatment polymers for textiles, carpets, leather, paper/packaging, paints, floor finishes, and sealants; made by fluorochemical manufacturers [1][2].

Indoor dust and air from treated items, contact with coated textiles/paper, contaminated drinking water near manufacturing sites or AFFF firefighting foam use, and workplace exposure [1][2].

Very persistent (“forever chemical”) and can degrade to PFOS. PFAS exposure has been linked to reduced vaccine response, higher cholesterol, developmental effects, and some cancers (e.g., PFOA) [1][3][5].

Fluorochemical and textile/paper workers; people near PFAS plants or firefighting training areas; pregnant people, fetuses, and infants (PFAS crosses the placenta and is found in breast milk) [1][3].

Choose PFAS‑free or untreated products; avoid optional stain‑/water‑repellent treatments; wet‑dust and HEPA‑vacuum; wash hands before eating; use certified filters (granular activated carbon or reverse osmosis) and check local water testing results [2][6].
