New PFAS analysis from TESTEX increases textile safety

(CONNECT) The Swiss textile testing institute TESTEX has announced the launch of its Non-Targeted PFAS Analysis. As an official OEKO-TEX representative, TESTEX therefore offers solutions that offer enhanced visibility into PFAS contamination, as detailed in a statement. Verified products receive the PFAS TESTED label, which is the independent certification mark of TESTEX. It confirms that the products have undergone extensive testing for the presence of per- and polyfluoroalkyl substances (PFAS). The label not only increases supply chain transparency, but also boosts consumer confidence and trust in the textiles they purchase.

The extensive group of PFAS chemicals comprises more than 10,000 synthetic substances. This class of substances is also known as “forever chemicals”. They can be found in textiles, food packaging, coatings and cosmetics. However, it is difficult to detect them simply due to the sheer number of chemicals in this group. The conventionally deployed targeted testing methods are currently limited to a restricted number of predefined, known substances.

“Many companies believe they are managing PFAS risks because they meet current regulatory requirements”, TESTEX writes. However, while this ensures compliance with legal regulations, the actual risk often remains undetected. Prohibited substances are frequently substituted by other PFAS that slip through the cracks of conventional analysis. The Non-Targeted PFAS Analysis method utilizes a high-resolution mass spectrometer (LC-HRMS) capable of identifying these hidden PFAS contaminations. As such, this new analytical method also serves as preparation for future regulatory developments. ce/eb
