Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.
“Since intact skin acts as an effective barrier to many toxins, it’s unlikely that people will absorb a significant amount of perfluorohexanoic acid — or other PFAS chemicals — through the ...
Trifluoroacetic acid, a moderately strong acid useful in organic chemistry. Heptafluorobutyric acid, a moderately strong acid that is useful in organic and analytical chemistry. Pentafluorobenzoic acid, a moderately strong acid of interest in research community. Perfluorooctanoic acid (PFOA),a surfactant used to make fluoropolymers such as Teflon.
Certain PFASs are no longer manufactured in the United States as a result of phase-outs including the PFOA Stewardship Program (2010–2015), in which eight major chemical manufacturers agreed to eliminate the use of PFOA and PFOA-related chemicals in their products and emissions from their facilities.
"The products are used by women for up to 8-10 hours at a time, in direct contact with a woman’s vaginal area, which is more vulnerable to exposure than via transdermal methods on the skin and ...
2016 The EPA "published a voluntary health advisory for PFOA and PFOS" which warned that "exposure to the chemicals at levels above 70 parts per trillion, total, could be dangerous." [71] 2016 The city of Lake Elmo, Minnesota, sued 3M a second time for polluting their drinking water with PFAS chemicals.
Simply Orange Juice is accused of deceiving health-conscious customers into believing one of its juices is “all natural” as labeled — but it’s not, a class-action lawsuit says.
Even though it is from a chemical perspective a relatively weak acid, it is far more dangerous than conventional strong mineral acids, such as nitric acid, sulfuric acid, or hydrochloric acid. Owing to its lesser chemical dissociation in water (remaining a neutral molecule), hydrogen fluoride penetrates tissue more quickly than typical acids.
