Most opaque nail lacquers arc solutions of nitrocellulose, plasticizers, and resins in mixed volatile organic solvents. Color and opacity arc produced by pigments suspended in the lacquer. In nail lacquers, n-butyl phthalate, camphor, and tricresyl phosphate arc common plasticizers; an aryl sulfonamide-formaldehyde polymer is a frequently used resin, and the pigments are likely to be organic lakes, guanine, and titanium dioxide. The solvents are usually mixtures of toluene, butyl acetate, acetate, ethyl acetate and isopropanol. A typical nail lacquer contains about 12% nitrocellulose, 5% n-butyl phthalate, 5% aryl sulfonamide-formaldehyde resin, 1-3% camphor, and 1-2% pigment. The solvent may approximate 35% toluene, 40% butyl acetate, 15% ethyl acetate, and 10% ethanol.
