Abstract:

The aim of the study was to establish a detection method for determination of 15 kinds of dyestuffs in hair dyes by high performance liquid chromatography(HPLC). The 15 kinds of dyestuffs were extracted with the mix of ethanol and water(Vethanol Vwater=6∶4) by the ultrasonic extraction method. The separation was performed on a Welch Xtimate-C18 column(4.6 mm×250 mm,5 μm) by gradient elution with the solution of 0.02 mol/L ammonium acetate and acetonitrile and determined by photo-diode array detector. The flow rate was 1.0 mL/min and the detection wavelength was 230 nm. The results indicate that each compound shows good linearity in its own concentration range with the correlation coefficient of R2>0.995.The limits of detection(LOD) are in the range of 0.86-7.63 μg/g. The average recoveries are ranged from 85.42% to 114.61%, and the relative standard deviation(RSD) is in the range of 0.72% to 8.65%. The method is simple, rapid, reliable and accurate, which is suitable for determination of 15 kinds of restricted dyestuffs in hair dyes.

Key words: hair dyes, restricted components, high performance liquid chromatography
