CAS 143372-54-7

Siloxanes and Silicones, (3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl)oxy Me, hydroxy Me, Me octyl, ethers with polyethylene glycol mono-Me ether

This fluorinated silicone polymer is a PFAS-containing surfactant used to make products repel water and stains in coatings and some personal-care or industrial formulations [2]. It matters because PFAS persist in the environment and can build up in people and wildlife [1][2].

Where It Comes From

Manufacturing and use in water- and oil-repellent coatings, treated textiles, and some cosmetic or cleaning products; releases to dust and wastewater during production and use [2][4].

How You Are Exposed

Contact with treated products, indoor dust, and drinking water near industrial sources; small amounts can migrate from consumer uses into air or water [1][2].

Why It Matters

PFAS exposure is linked to immune effects, high cholesterol, liver and thyroid changes, developmental harms, and, for some PFAS like PFOA, cancer [1][2][3].

Who Is at Risk

People near PFAS manufacturing or contaminated water, workers handling PFAS formulations, pregnant people, infants and children [1][4].

How to Lower Your Exposure

Check local water advisories; use certified filters for PFAS; minimize stain-resistant sprays and water-repellent treatments; damp-dust and use a HEPA vacuum; follow workplace safety guidance [2][4].
