Poly(oxy-1,2-ethanediyl), α-methyl-ω-hydroxy-, 2-hydroxy-3-[(γ-ω-perfluoro-C6-20-alkyl)thio]propyl ethers

Making/using fluorinated surfactants and repellents for metal plating, textiles, paper/packaging, and specialty coatings; related PFAS have also been used in firefighting foams (AFFF) [1][2].

Drinking water near industrial sites or military bases using PFAS, indoor dust, treated consumer goods, and workplace air or skin contact [1][2][3].

Many PFAS last for decades; some are linked to higher cholesterol, liver and immune effects, reduced vaccine response, and developmental effects [1][3].

Workers handling PFAS, firefighters using AFFF, people relying on contaminated private wells, pregnant people, and infants (via formula mixed with contaminated water) [1][2][4].

Use PFAS‑reducing water filters (activated carbon, ion exchange, or reverse osmosis) certified by an independent program; follow local water advisories; limit use of stain‑/water‑repellent treatments; wet‑mop and HEPA‑vacuum dust; follow workplace protections [2][4].
