Abstract
Five hair dye components were tested for their mutagenicity at the TK +/- locus of L5178Y cells. Three of the components, m-phenylenediamine, 2 nitro-p-phenylenediamine, and 4-nitro-o-phenylenediamine, gave a positive response that was dose related; 2,4-diaminoanisole gave a questionable response; and 2,5-diaminoanisole gave a negative response. The assay was carried out in vitro without metabolic activation during a 24-hr chemical exposure period. It is concluded that further in vivo tests are necessary to establish the safety of the hair dyes.Entities:
