perfluorodecanoic

Perfluorodecanoic acid, often abbreviated as PFDA, is a synthetic perfluorinated carboxylic acid with the chemical formula C10F20O2. It belongs to the broader class of per- and polyfluoroalkyl substances (PFAS), which are known for their extreme stability and resistance to degradation. PFDA consists of a ten-carbon chain where all hydrogen atoms have been replaced by fluorine atoms, capped by a carboxylic acid group.

This chemical structure imparts unique properties, making PFDA useful in various industrial applications. It has been employed as a surfactant, a component in firefighting foams, and in the manufacturing of certain polymers and coatings. Its ability to repel both water and oil has contributed to its use in products like stain-resistant fabrics and food packaging.

However, like other PFAS, PFDA is persistent in the environment and can accumulate in living organisms. Concerns have been raised about its potential health effects, although research is ongoing. Due to its environmental persistence and potential for bioaccumulation, its use and production are increasingly scrutinized, with regulatory actions being implemented in various regions to limit its release and exposure.
