PFAS or polyflurorinated alkyl substances are highly toxic synthetic chemicals, which are harmful to our health and the planet. They are also known as PFOA, PFOS, PFCs/Fluorocarbons or GenX. They are present in most traditional fabric protectors. They have been shown to have a causal link to changes in the liver, thyroid and pancreas, as well as hormonal changes, which can lead to potential cancer risk. PFAS are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time.
