PFHxA

Perfluorohexanoic acid, often abbreviated as PFHxA, is a synthetic chemical that belongs to the larger group of per- and polyfluoroalkyl substances (PFAS). These substances are characterized by their strong carbon-fluorine bonds, which make them highly resistant to degradation in the environment and in the human body. PFHxA has a chain length of six carbon atoms.

PFHxA has been used in a variety of industrial and consumer applications. Historically, it was employed in products such as firefighting foams, stain repellents, food packaging, and as a processing aid in the manufacturing of certain plastics and textiles. Due to its chemical properties, it can repel both water and oil.

Like other PFAS, PFHxA is considered persistent, meaning it does not break down easily. This persistence leads to its accumulation in the environment, including soil, water, and air, as well as in living organisms. Studies have detected PFHxA in human blood and tissues. Research into the potential health effects of PFHxA exposure is ongoing, with some studies suggesting possible links to issues such as liver effects, immune system impacts, and developmental changes, though more conclusive research is needed. Regulatory bodies worldwide are increasingly scrutinizing and implementing measures to control the production and release of PFAS, including PFHxA.
