AB  - A method has been established for the simultaneous determination of 38 limited 
      colorants in cosmetics by high performance liquid chromatography (HPLC). The 
      samples were extracted by ultrasonic with tetrahydrofuran, methanol, ammonium 
      acetate solution as extraction solvents. After centrifugation, nitrogen blow and 
      redissolved in turn, the extracts were separated on an Agilent zorbax SB-Aq 
      column (150 mm x 3.0 mm, 3.5 microm) using a gradient elution program with 
      acetonitrile and 30 mmol/L ammonium acetate containing 0.075% (v/v) formic acid 
      as mobile phases. The detection wavelengths were set at 254, 416, 484, 514, 590 
      and 620 nm. The linear ranges of the 38 target compounds were all in the range of 
      1 to 10 mg/L with correlation coefficients more than 0.999. The limits of 
      quantification (LOQs) for the 38 colorants were in the range of 5-50 microg/g. The 
      average recoveries at two spiked levels ranged from 93.2% to 107.6% with the 
      relative standard deviations (RSDs) less than 10% (n = 6). This method is 
      accurate, simple, sensitive and reliable, and can be used for the analysis of the 
      38 limited colorants in cosmetics.
