Gas-liquid chromatographic determination of solvents in commercial nail lacquer preparations.
A gas-liquid chromatographic (GLC) method has been developed for the determination of 5 solvents (butanol, butyl acetate, ethyl acetate, 2-propanol, and toluene) and camphor in commerical nail lacquer preparations. Resins and pigments are first precipitated from the solvents by dilution with isooctane. n-Propyl acetate is then added as an internal standard to the isooctane solution of solvents and the mixture is analyzed by temperature-programmed GLC. Analyses at 3 concentration levels (4, 20, and 40%) with 4 determinations at each level gave good recoveries.
