In January, France became the first country in Europe to restrict PFAS in consumer textiles. Law 2025-188 applied to clothing from the start of 2026, with wider categories following later. Denmark's ban on PFAS in consumer clothing takes effect this month. At EU level a broad restriction proposal under REACH was pulled back and replaced in October 2025 with a narrower one, which is still working its way through the process. Spain has no textile-specific ban.
People assume I have strong feelings about this because of my son. I do, but not the ones they expect.
What I actually know about my son's uniform
When he was small he had a severe skin reaction to a school uniform. It was a rigid synthetic garment, poorly finished, and the reaction was bad enough that it changed the direction of my career. What I have never been able to tell you is what caused it. I did not have the garment tested. I did not know then what I know now about how to ask. It could have been a residual finishing agent, a dye, mechanical irritation from a stiff fabric against skin, or something else entirely. I am not going to attach it to PFAS in order to make a point. That would be exactly the sort of unevidenced claim I spend my working life asking other people to substantiate.
What the episode did teach me is the thing I still believe. A parent has no practical way of finding out what is in a garment, and that is a design failure rather than a chemistry problem.
What PFAS are, proportionately
PFAS are a family of several thousand fluorinated compounds, used in textiles almost entirely for one purpose: repellency. Water off a coat, ketchup off a shirt, a stain-release finish on a school polo. They work extremely well, which is why they persisted after the trade moved from long-chain C8 chemistry to shorter-chain C6 in the 2010s. The regulatory concern is not acute harm from wearing a treated shirt for a day. It is persistence. These molecules do not break down meaningfully in the environment, they accumulate, and several are associated with health effects at population level. Regulators are acting on the accumulation, not on any single garment.
The proportionate position for a school, then, is not alarm. It is that a stain-resistant finish is a convenience, and it is fair to ask whether that convenience is worth a persistent compound in clothing a child wears daily, when workable alternatives exist.
The alternatives are ordinary
For most school uniform, repellency is not a genuine requirement at all. Where it is, in an outdoor jacket, there are non-fluorinated routes: silicone-based finishes, hydrocarbon dendrimer treatments, and, most usefully, construction. A tightly woven fabric with a high thread count and a properly calendered finish sheds a good deal of water on its own. The trade-off is honest and worth stating: non-fluorinated repellents handle water well and oil poorly, so they resist rain but not chip fat. For a nine-year-old's coat, that is a trade I would make without hesitating.
Ask for the report, not the word
The phrase PFAS free on a label means close to nothing without a method behind it. What I ask a supplier for is the restricted substance test report covering the actual production lot, not a general statement from head office. Two things to look for. First the screening method: total fluorine or extractable organic fluorine by combustion ion chromatography is the usual first pass, followed by targeted analysis for named compounds. Second the detection limit, because a result of not detected only means something once you know what the instrument was capable of detecting.
Then check the date. A report from 2023 does not describe a garment made in 2026. This is why we attach reports to the production lot rather than to a product page, and why the record carries a review date. A certificate without an expiry is a photograph presented as a live feed.
France has decided that a stain-resistant school shirt is not worth a persistent fluorinated compound. I expect Spain will get there. In the meantime the decision is not out of a school's hands: it takes one question in a tender document, and a supplier who cannot answer it has told you something useful anyway.
