1-Propanaminium, 2-hydroxy-N,N,N-trimethyl-, 3-[(γ-ω-perfluoro-C6-20-alkyl)thio] derivs., chlorides

This chemical is a fluorinated surfactant in the PFAS family, used to repel water and oil on products and in industrial processes. PFAS are extremely persistent in the environment and some have been linked to health harms; data on this specific mixture are limited, so concerns are based on the PFAS class [1][2].

Where It Comes From

Manufactured PFAS used in stain-, water-, and grease‑resistant treatments and industrial coatings/surfactants; can be released to air, water, and waste streams [1][2].

How You Are Exposed

Drinking water near contaminated sites, food contact materials, household dust, and workplaces that make or use PFAS-treated products [1][2][3].

Why It Matters

PFAS can build up in people and the environment; some are associated with immune effects (reduced vaccine response), increased cholesterol, liver changes, and developmental effects during pregnancy and early life [1][2].

Who Is at Risk

Workers handling PFAS, people with contaminated private wells or systems, pregnant people, infants/young children (including via breast milk) [1][2].

How to Lower Your Exposure

Check local water advisories; use NSF-certified filters (activated carbon or reverse osmosis) shown to reduce PFAS; reduce use of stain‑resistant treatments; wet‑dust/vacuum with HEPA; follow fish/foam advisories near contaminated waters [1][2][3].
