It breaks down to form perfluorooctane sulfonate (PFOS). The perfluorooctanesulfonyl fluoride -based chemistry that was used to make sulfonamides like PFOSA was phased out by 3M in the United States (US) during 2000–2002 but it has grown in China by other producers.
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.
PFOA is a perfluoralkyl carboxylate that is produced synthetically as a salt Ammonium salt is the most widely produced form (EFSA 2008; EPA 2009c). Perfluorooctane sulfonate (PFOS) and its salts are perfluorinated organic compounds with surfactant properties. Common salts of PFOS include the ammonium, diethanolamine, potassium, and lithium forms. PFOS can be released from several fluorochemicals, such as perfluorooctane sulfonamide The physical and chemical properties of the potassium salt of PFOS are listed in Table 2. Table 2. Physical and chemical properties of PFOS potassium salt.

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. Paul, Minnesota).
