Perfluorooctanesulfonic acid is usually used as the sodium or potassium salts. PFOS was the key ingredient in Scotchgard , a fabric protector made by 3M , and numerous stain repellents. PFOS, together with PFOA , has also been used to make aqueous film forming foam (AFFF), a component of fire-fighting foams , and alcohol-type concentrate foams .

Product Format. Neat. Solvent Perfluorooctane-1-sulfonic acid (PFOS) is emerging as an important persistent environmental pollutant. To gain insight into the interaction of PFOS with biological systems, the mixing behavior of dipalmitoylphosphatidylcholine (DPPC) with PFOS was studied using differential scanning calorimetry (DSC) and fluorescence anisotropy measurements.

Common salts of PFOS include the ammonium, diethanolamine, potassium, and lithium forms. PFOS can be released from several fluorochemicals, such as perfluorooctane sulfonamide Perfluorooctane sulfonic acid 1763-23-1 C 8HF 17O 3S 500.13g/mol Ammonium salt 29081-56-9 C 8H 4F 17NO 3S 517.15g/mol Diethanolamine salt 70225-14-8 C 12H 12F 17NO 5S 605.26g/mol Potassium salt 2795-39-3 C 8F 17KO 3S 538.21g/mol Lithium salt 29457-72-5 C 8F 17LiO 3S 506.06g/mol Melting point >400°C (acid) (OECD 2002) Boiling point no data 1 Perfluorooctane sulfonate (PFOS) is an emerging persistent organic pollutant widely distributed in the environment, wildlife, and human. In our studies, as observed under the transmission electron microscope, PFOS increased autophagosome numbers in HepG2 cells. It was confirmed by elevated LC3-II levels in Western blot analysis. Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are fluorinated hydrocarbons used as water-, oil-, and stain-resistant coatings in fabrics, leather, and carpets, and oil-resistant coatings for paper products for food contact, and also as photographic emulsifier, aviation … Wilkins, P (2001a) Perfluorooctanesulfonate, potassium salt (PFOS): An acute oral toxicity study with the honey bee.
