About
A pyridine-based azo dye with hazard statements H302, H373, H411 requiring caution; structurally similar to hair dye intermediates restricted in EU Annex III.
This pyridyl-azo-pyridine compound carries hazard statements H302 (harmful if swallowed), H373 (may cause organ damage through prolonged exposure), and H411 (toxic to aquatic life). The azo bond in a pyridine heterocyclic system can be reduced under certain conditions to release potentially harmful aromatic amines. While not specifically restricted in EU cosmetics, the hazard profile and structural similarity to restricted hair dye intermediates warrant caution. The compound requires careful formulation control and would likely be restricted to rinse-off applications only.
Known concerns
- H302 harmful if swallowed
- H373 potential organ damage with prolonged exposure
- H411 aquatic toxicity
- Azo dye reduction concern
- Similar to restricted hair dye intermediates
