The basic ingredients that go into a nail polish are film forming agents, resins, plasticizers, solvents and coloring agents. But there are three specific ingredients that researchers have found to be toxic and potentially cancer-causing: Formaldehyde, Toluene and DBP (Dibutyl phthalate), aka The Big 3.
But don’t panic! The FDA regulates nail products and they recognize that although they contain potentially harmful ingredients, but are allowed on the market because they are safe when used as directed. So ladies, don’t make a habit of sniffing your pail polish or biting your nails.
For those of you who want to avoid all of these potentially dangerous ingredients altogether, there are some exciting non-toxic (3-Free) nail polish lines out there.
