Use：Perfluorinated surfactants consist of a broad class of fluorinated chemicals of differing structures, physical–chemical properties, and modes of toxic action. This class of compounds is made up of fully fluorinated organic compounds that due to their unique chemical properties can be used in a variety of industrial processes and products. Some characteristics of these chemicals are the ability to repel water and oil, reduce surface tension, catalyze oligomerization and polymerization, and maintain their properties under extreme conditions. Sulfonyl-based perfluorochemicals are produced by an electrochemical fluorination (ECF) process where hydrogen atoms of a feedstock are replaced with fluorine atoms. Perfluorooctane sulfonyl fluoride (POSF) is the principal product from this process and it has been used in a variety of products that can be divided into three main categories: surface treatments (carpet and textile protection), paper protection (grease, oil, and water resistance), and performance chemicals (firefighting foams, mining surfactants, and electronic etching baths). Depending on the degree of derivatization and polymerization, POSF products can degrade to perfluorooctane sulfonate (PFOS), a stable end product that is resistant to degradation. Commercially, ECFproduced PFOS consists of linear (70%) and branched (30%) isomers that have differing environmental and toxicological properties. However, due to the presence of PFOS in biota from sites remote from production, as well as its presence in human blood, PFOS has been voluntarily withdrawn from commercial production in the United States.
