History
Thousands of years ago, the Chinese used a colored lacquer, made from gum arabic, egg whites, gelatin, beeswax and plants.
Egyptions used henna to color their nails.

Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder.
This powder is added to a vehicle (or binder), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.

Pure pigment allows very little white light to escape, producing a highly saturated color.
A small quantity of pigment mixed with a lot of white binder, however, will appear desaturated and pale, due to the high quantity of escaping white light.

Eco-friendly nail polish
A recent development (ca. 2003) is water-based nail polish, which is based on an acrylic polymer emulsion (e.g. styrene-acrylate copolymer), and pigments similar to those used in watercolor paints.
- Odor free - No more solvent-based nail enamel - Don’t last as long - Lacks complete coverage
