PFAS are measured in two different ways at OEKO-TEX®. First, all legally restricted PFAS are measured separately, to make sure that OEKO-TEX® certified products are compliant with the EU/US laws. Then, the sum of extractable organic fluorine is measured. This includes fluorine from PFAS and also fluorine from other organic molecules such as fluorine-based dyes, which are not considered a threat to human health or the environment. The goal of this limit value is not to forbid the use of all fluorines, but rather to ban the intentional use of PFAS.
