Abstract
Hair dyes contain strong allergens and are widely available. Correct labeling is a necessity in order to provide information about the contents, aromatic amines of color precursor are commonly derived from phenylene amine sulfuric acid or para phenylene diamine sulfuric acid. More study in hair dye precursor showed the toxicity behavior and carcinogenesis by contact with aminophenols and 1-4 benzodiazines. The aim of this study was to identify 6 aromatic amines used in commercial hair dye substances by 4 developing solvents and 2 indicator sprays, using a thin layer chromatography (TLC) method. The aromatic amines substances were identified by comparing the Rf values and colors between samples and reference substances.The results showed that each sample contains 3-5 aromatic amines. The superiority of this method in the present study was compared with high performance liquid chromatography (HPLC) and four laboratories participated in the validation and the results showed good interlaboratory reproducibility.
