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

This is a fluorinated acrylic polymer used to make fabrics, carpets, paper, and paints repel water, oil, and stains. It’s part of the PFAS family and can contain or break down into other PFAS that persist in the environment and may harm health [1][2].

Where It Comes From

Stain-/water-resistant treatments on textiles, upholstery, carpets, leather, outdoor gear, and paper/packaging; releases can occur during manufacture, use, and disposal [1][2].

How You Are Exposed

Breathing or ingesting indoor dust from treated items; washing that sends residues to wastewater; and drinking water/food contaminated by PFAS formed as breakdown products (e.g., PFOA, PFNA) [1][2].

Why It Matters

PFAS last a long time, build up in people and wildlife, and some are linked to high cholesterol, reduced vaccine response, liver/thyroid changes, pregnancy risks, and cancer (PFOA) [1][2][3].

Who Is at Risk

Workers handling PFAS; households with many treated carpets/upholstery; young children (more dust intake); pregnant people; communities near PFAS-contaminated water sources [1][2][4].

How to Lower Your Exposure

Choose PFAS‑free products; vacuum with HEPA and wet‑dust; ventilate rooms; limit grease‑resistant packaging; wash hands; use certified RO or activated‑carbon water filters and consider testing your water [2][4][5].
