Abstract: A reliable Gas Chromatography-Mass Spectrometry(GC-MS) method was developed for the simultaneous determination of 17 dye intermediates, including benzenediamines, aminophenols, benzenediols, naphthalenediol and diaminopyridine, in oxidative hair dyes. Samples were extracted with 50% ethanol by adding sodium dithionite to prevent oxidation. A DB-WAX capillary column was selected for the separation of both water soluble and alcohol soluble hair dye intermediates. The results showed that 17 dye intermediates were well separated within 25 min. The detection limits of these compounds were in the range of 2-380 mg/kg. The recoveries of the target compounds in hair dyes ranged from 81.1% to 103.7% with four addition levels. The method described was validated by 5 different laboratories and successfully applied to the analysis of commercial oxidative hair dyes.
