Abstract excerpt
The hair-dye ingredients, HC Blue No. 1 (HCB1) and HC Blue No. 2 (HCB2), were tested for the induction of bacterial mutation using Salmonella typhimurium strains TA1535, TA1537, TA98 and TA100; and Escherichia coli strains WP2uvrA-. In addition, both dyes were evaluated in the mouse lymphoma L5178Y TK+/- assay (MLA) for the potential to induce forward mutation. A liver homogenate (S9) prepared from Aroclor...
