CAS 65530-64-5

Ethanol, 2,2'-iminobis-, compd. with α,α'-[phosphinicobis(oxy-2,1-ethanediyl)]bis[ω-fluoropoly(difluoromethylene)] (1:1)

A PFAS-based surfactant used in industrial coatings and manufacturing. PFAS persist in the environment and can contaminate water; health insights here rely on related, better-studied PFAS, some linked to harm [1][2].

Where It Comes From

Made/used as a wetting or leveling agent in fluorinated coatings, inks, and other processes; releases can occur during production, use, or disposal [2].

How You Are Exposed

Workers by skin or inhalation. Nearby residents via contaminated drinking water, surface water, or dust; consumer contact from treated surfaces is expected to be low [1][2].

Why It Matters

Very persistent; some PFAS build up in people. Exposure to well‑studied PFAS is linked to higher cholesterol, liver/thyroid changes, lower vaccine response, and some cancers [1][3].

Who Is at Risk

Workers handling PFAS mixtures; people near fluorochemical plants, metal plating, or firefighting training sites; pregnant people, infants, and private‑well users nearby [1][2].

How to Lower Your Exposure

If on a private well, test for PFAS; use NSF/ANSI 53 or 58 filters. Follow water/fish advisories. At work, use PPE and hygiene; wet‑wipe or HEPA‑vacuum dust [1][2][4].
