Artificial nail products are composed of various chemicals. The main ingredient for most artificial nail products is ethyl methacrylate (KMA). In 1974 the U.S. Food and Drug Administration (FDA) banned a similar chemical, methyl methacrylate (MMA), for use in nail products because of its harmful effects during application. Despite the FDA ban, MMA is still found in trace amounts in some products.
