1,4-Benzenedicarboxylic acid, dimethyl ester, reaction products with bis(2-hydroxyethyl)terephthalate, ethylene glycol, α-fluoro-ω-(2-hydroxyethyl)poly(difluoromethylene), hexakis(methoxymethyl)melamine and polyethylene glycol

A “side‑chain fluorinated” polymer made by reacting polyester components with fluorinated alcohols and melamine; used in stain‑resistant carpets, upholstery, apparel, paper/food packaging, and protective coatings [2][6].

Indoor air and dust from treated products; applying sprays or finishes; contaminated drinking water near manufacturing or waste sites; contact with treated food packaging [1][2].

PFAS are extremely persistent; some related PFAS are linked to developmental, immune, liver effects and certain cancers. These polymers can contain residual fluorotelomer alcohols and transform into perfluoroalkyl acids over time [1][2][3][6].

Workers in textile, paper, and coating facilities; people living near PFAS plants or waste sites; pregnant people, infants, and children [1][2].

Choose PFAS‑free/“fluorine‑free” products; skip optional stain‑resistant treatments; ventilate during use; clean with HEPA vacuum and damp dusting; wash hands; use certified filters (activated carbon or reverse osmosis) and follow local water advisories [1][2][4][5].
