A … Chemical name: Ammoniumpentadecafluorootanoate (APFO) Molecular formula: C8F15O2NH4 CAS number 3825-26-1 Perfluorooctane sulfonic acid (PFOS) is the most prominent of the perfluoroalkane sulfonic acids (PFSAs). PFOS has a linear perfluoroalkyl carbon chain of 8 atoms and a sulfonic acid functional group (Danish EPA, 2013). Successful alternatives to PFOS materials have included non-perfluorinated chemicals such as hydrocarbon surfactants, chemicals with short perfluorinated chains (C3 - C4), silicones, telomers. In very few cases, it has been possible to reformulate coatings … Perfluorooctane Sulfonate (PFOS) and related chemical products – OECD webportal .

Perfluorooctanesulfonic acid (PFOS) (conjugate base perfluorooctanesulfonate) is an anthropogenic fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009.

Some early applications included nonstick cookware, waterproof coatings Branched PFOS had shorter half-lives than linear PFOS. Both PFOA and PFOS half-lives in the present study were shorter than published estimates, suggesting a possible time-dependent PFAS elimination process, with more rapid elimination in the first few months after the end of exposure. The Occupational Safety and Health Administration has clear requirements for how hazardous chemicals must be labeled. These rules are designed to ensure consistency and that everyone has a clear understanding of the dangers involved with wo This is a list of common chemicals and where you can find them or how you can make them. Both compounds and pure elements are included. This is a list of common chemicals and where you can find them or how you can make them.
