  2. History • 17th- and 18th-century European royal courts wrote about painting their nails • Recipe books from both Britain and the U.S. both had instructions for making nail paints

  3. Ingredients • Key ingredient is nitrocellulose • Ahighly combustible material that is also used in making dynamite, creates a film that holds together other substances • Main component used for car paint in the 1920’s • Fireworks known as "gun cotton“ • Dissolved in ethyl acetate liquids. • The polymers cement to the nail bed, keeping the polish on the nail. When the polish dries, the polymers harden and this is the reason why the polish does not slide off the nail.

  4. Today’s Nail Polish • Plasticizers embed between polymer chains, making polish flexible • Dibutylphthalate and camphor are used to improve the flexibility of the film. • Pigments and sparkling particles, such as mica, are also added. • Stearalkoniumhectoriteis added to: • Keep the glittery particles from sinking to the bottom of the bottle. • Used as a thickening agent • To keep the other ingredients from separating and to make the polish easier to apply.

  5. Changes in nail polish • Dibutyl phthalate: could interfere with the endocrine system • Toluene: many companies have also eliminated the solvent in response to safety concerns

  6. Pigments • There’s a wide variety of chemicals used as pigments in nail polish. • Common pigments include iron oxides and other colorants, such as you would find in paint or varnish.
