Thinx contains the harmful chemicals PFAS. PFAS can be found in a lot of hygiene and cosmetics products, I'm also reminded by Always selling scented and low-quality pads that give women rashes. I think this is a feminist issue. As women, we are often exposed to more chemicals through makeup and hygiene products, but apparently no one gives a crap about that.
