Forever chemicals are everywhere, including in period and incontinence products—even in some that companies claim are free of such substances.
That’s the conclusion from independent lab testing we solicited that looked for signs of per- and polyfluoroalkyl substances (PFAS) in 44 products—including period underwear, tampons, menstrual cups, and more—and found plenty.
Often called “forever chemicals” because they can take years or even centuries to degrade, PFAS are associated with numerous personal and environmental health risks. They’re virtually inescapable in everyday life, having been added to or detected in everything from food wrappers and cookware to cosmetics and drinking water. Manufacturers often use them to make some fabrics waterproof, leakproof, or stain-resistant, as well.
