CAS 678-39-7

1-Decanol, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluoro-

This fluorotelomer alcohol (often called 8:2 FTOH) helps make stain- and water-resistant coatings. It can escape from products into indoor air and break down into persistent PFAS like PFOA [1][2].

Where It Comes From

PFAS-treated carpets, textiles, food packaging, and industrial coatings; releases during manufacturing and product use [1][2].

How You Are Exposed

Breathing indoor air and dust, handling treated items, some food contact materials, and being near industrial sources [1][2].

Why It Matters

Precursor to PFOA and related PFAS linked to liver, immune, cholesterol, and developmental effects; PFOA is carcinogenic [1][3][4].

Who Is at Risk

PFAS manufacturing/applicator workers; carpet care staff; households with many stain‑resistant items; pregnant people, infants, and children [1][4].

How to Lower Your Exposure

Choose PFAS‑free goods; avoid “stain‑resistant” or “fluoro/PTFE” labels; ventilate, HEPA‑vacuum and wet‑dust; limit greasy fast‑food wrappers; use certified PFAS water filters if advised [1][2].
