France has become the first country in the EU to officially ban the use of PFAS, or “forever chemicals,” in cosmetics, textiles, clothing, shoes and ski wax.

Forever chemicals are persistent chemical compounds that remain in nature for a long time and can accumulate in the human body. They are used in products with water- and grease-repellent properties and are linked to serious health risks, including cancer and immune system disorders.

The ban does not apply to critical equipment or nonstick cookware. It also includes monitoring of forever chemicals in water sources. The decision is part of a growing international movement: similar measures have already been adopted in Denmark and are under discussion in other EU countries.

Fourteen members of the National Assembly had their hair tested for forever chemicals — and all of them tested positive. The gesture caused a public response and helped give the initiative additional weight.
