Abstract:

A high performance liquid chromatography (HPLC) method for the determination of 5 restricted dyes in hair dyeing cosmetics was established. The sample was extracted and filtered, separated by an Agilent ZORBAX SB-C18 column (250 mm×4.6 mm, 5 μm), and gradient elution with methanol as mobile phase A and 5 mmol/L ammonium acetate solution as mobile phase B. The elution was performed at a flow rate of 1.0 mL/min and the column temperature was set at 30 ℃. The analysis was done using photo-diode array detector. Standard curve method was used for quantification. The results show that the linear correlation coefficients of the five restricted dyes are all greater than 0.999. The average recoveries at three spiked levels of the five restricted dyes are in the range of 92.5%-106.0% with RSDs of 0.5%-4.1%.

Key words: restricted dyes, cosmetics, high performance liquid chromatography
