In recent years, the conversation around PFAS (per- and polyfluoroalkyl substances)—the so-called "forever chemicals"—has grown louder, and for good reason. Known for their durability and resistance to heat, oil, and water, PFAS are present in countless products, including cosmetics and personal care items. These substances not only serve functional purposes, like creating emulsions or providing oil-resistant properties, but they also appear unintentionally as contaminants or impurities in pigments, methicone, acrylates, and more.
