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.

Asthma/Respiratory . No Data, Some Concern Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) belong to the group of per‐and polyfluoroalkyl substances (PFASs). PFASs (R‐X) are compounds consisting of a hydrophobic alkyl chain, of varying length (typically C4–C16) and a hydrophilic end group. Perfluorooctane sulfonate The PFOS used in this study was potassium perfluorooctanesulfonate salt (CASRN 2795-39-3, K + PFOS, lot 217, purity 86.9%) obtained from 3M Company (St.

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. /Perfluorooctane sulfonic acid, potassium salt/ Brooke D et al; Environmental Risk Evaluation Report: Perfluorooctanesulphonate (PFOS), 2004. Environment Agency, Chemicals Assessment Section, United Kingdom. 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.

Sufficient information exists to address hazard classification for all SIDS human health endpoints. for example the potassium salt of PFOS has a solubility in fresh water of 370 mg/L and of 25 mg/l in filtered sea water. Chemical Name: Perfluorooctane Sulfonate Synonym: PFOS CAS: 1763-23-1 (acid) 29081-56-9 (ammonium salt) 70225-14-8 (diethanolamine salt) 2795-39-3 (potassium salt) 29457-72-5 (lithium salt) Serum concentrations appear to be the best dose-metric for extrapolating to humans.
