2-Propenoic acid, 2-methyl-, octadecyl ester, polymer with 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-heneicosafluorododecyl 2-propenoate, 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl 2-propenoate and 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,14-pentacosafluorotetradecyl 2-propenoate

Stain- and water‑repellent treatments on textiles, carpets, outdoor gear, leather, and some paper/food packaging; manufacturing and spray applications [1][2].

Indoor dust from treated carpets and furniture, contact with treated clothing/gear, air during spray use, and contaminated drinking water near PFAS production or firefighting foam sites [1][2].

PFAS are very persistent; some build up in people. Health concerns include higher cholesterol, reduced vaccine response, liver effects, and developmental impacts; PFOA (a related breakdown product) is a known human carcinogen [1][3][5].

Infants and children (hand‑to‑mouth/dust), pregnant people and fetuses, workers applying repellents, and communities near PFAS manufacturing or contaminated water [1][2][4].

Choose PFAS‑free textiles/packaging, avoid “stain‑proof” sprays, reduce indoor dust, ventilate if applying coatings, wash hands before eating, check local water quality, and consider certified filters (activated carbon or reverse osmosis) if needed [1][2][4].
