Certain kinds of greaseproofing “forever” chemicals called per- and polyfluoroalkyl substances, or PFAS, will no longer be used in food packaging in the US, the US Food and Drug Administration ...
Per- and polyfluoroalkyl substances. Per- and polyfluoroalkyl substances (PFAS[1] or PFASs[2]) are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain; there are 7 million such chemicals according to PubChem. [3] PFAS came into use after the invention of Teflon in 1938 to make ...
Environment portal. Ecology portal. v. t. e. Persistent organic pollutants (POPs) are organic compounds that are resistant to degradation through chemical, biological, and photolytic processes. [1] They are toxic and adversely affect human health and the environment around the world. [1]
Perfluoroalkoxy alkane. Perfluoroalkoxy alkanes (PFA) are fluoropolymers. They are copolymers of tetrafluoroethylene (C 2 F 4) and perfluoroethers (C 2 F 3 OR f, where R f is a perfluorinated group such as trifluoromethyl (CF 3)). The properties of these polymers are similar to those of polytetrafluoroethylene (PTFE).
Although the dangers of so-called forever chemicals are well-documented, these harmful substances have been detected in a range of personal care products used by consumers on a daily basis. For ...
GenX is a Chemours trademark name for a synthetic, short-chain organofluorine chemical compound, the ammonium salt of hexafluoropropylene oxide dimer acid (HFPO-DA). It can also be used more informally to refer to the group of related fluorochemicals that are used to produce GenX. [1][2] DuPont began the commercial development of GenX in 2009 ...
