What is PFOS?

Perfluorooctane Sulphonate (PFOS) is a fully fluorinated anion which is widely used for waterproofing and as an oil-resistance surface treatment for textiles, leather, and paper. PFOS may also be used as an intermediate to produce paints.


Eurofins | BLC Leather & Textile PFOS Testing to 1µg/m2

Eurofins | BLC, are able to accurately test leather and textile to 1µg/m2 using Liquid Chromatography – Mass Spectrometry (LC-MS). This ability to measure in such fine quantities enables Eurofins | BLC to identify even the smallest quantity of PFOS in your products.

Using these results, Eurofins | BLC can help your business to comply with chemical and product safety legislation.


Why test for PFOS?

PFOS has been classified as persistent, bio-accumulative and toxic (PBT) and, as a result, has been restricted under Persistent Organic Pollutants (POPs). PFOS is a highly toxic substance that is very mobile in the environment and often referred to as a global pollutant.


PFOS limits under Persistent Organic Pollutants (POPs)

  • PFOS shall not be used as a substance or constituent of preparations in products with a concentration equal to or higher than 0.005% by mass
  • Semi-finished products or articles, or parts shall not be places on the EU market if the concentration of PFOS is equal to or higher than 0.1% by mass
  • For textiles, leather or other coated materials, the concentration shall not be higher than 1µg/m2
