About
A cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
This amino-nitroanthraquinone derivative functions as a reactive dye intermediate, primarily used in hair coloring formulations to produce deep violet, blue, or teal shades. It carries H317 (skin sensitisation), H351 (suspected of causing cancer), and H413 (may cause long-lasting harmful effects to aquatic life) classifications. The nitro group and anthraquinone structure together raise significant toxicological concerns, and the H351 classification in particular warrants caution in consumer product formulations.
