Nail polish today is a refined version of the paint on vehicles. Most nail polishes are made of nitrocellulose dissolved in a solvent (e.g. butyl acetate or ethyl acetate) and either left clear or colored with various pigments. Basic components include: film forming agents (silver halide), resins and plasticizers, solvents, and coloring agents. Adhesive polymers (e.g. tosylamide-formaldehyde resin) ensure that the nitrocellulose adheres to the nail's surface. Plasticizers (e.g. camphor) are chemicals that link between polymer chains, spacing them to make the film sufficiently flexible after drying. Pigments and sparkling particles (e.g. mica) add desired color and reflecting characteristics. In addition, coloring "may also be attributable to the presence of chemicals such as chromium oxide greens, chromium hydroxide, ferric ferrocyanide, ferric ammonium ferrocyanide, stannic oxide, titanium dioxide, iron oxide, carmine, ultramarines, and manganese violet.” In order to get that glittery/shimmer look in the color, mica, bismuth oxychloride, natural pearls, and aluminum powder are added into the ingredients of the nail polish.Thickening agents (e.g. stearalkonium hectorite) are added to maintain the sparkling particles in suspension while in the bottle. Ultraviolet stabilizers (e.g. benzophenone-1) resist color changes when the dry film is exposed to direct sunlight. Along with Petroleum, with makes the nail polish smooth.
Nail polish makers are under pressure to reduce or to eliminate toxic ingredients, including phthalates, toluene, and formaldehyde. In September 2006, several makers agreed to phase out dibutyl phthalate, which has been linked to testicular problems in lab animals and humans, in updated formulations.Some makers eliminated formaldehyde from their products, others still use it.The city of San Francisco enacted a city ordinance, publicly identifying establishments that use nail polishes free of the "toxic trio" of toluene, dibutyl phthalate and formaldehyde.
Studies performed on female rats discovered that DBP, also known as phthalates, have been causing birth defects. It was soon removed from the ingredients of nail polish as a precaution. "The amount of chemicals used in animal studies is probably a couple of hundred times higher than what you'd be exposed to from using nail polish every week or so," says Paul Foster, PhD, a senior fellow at the National Institute of Environmental Health Sciences, a division of the U.S. Department of Health and Human Services. "So the chance of any individual phthalate producing such harm is very slim."
