Avoid

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Basic Red 1:1 is a cationic xanthene hair dye whose use the EU strictly limits because of genotoxicity and sensitization signals. It should appear, if at all, only in tightly controlled hair coloring products.

Skin benefits

  • Provides intense pink to red coloration in hair dyes
  • Historically used for vivid fashion hair shades

Known concerns

  • SCCS evaluations flagged genotoxicity concerns at higher levels
  • Restricted use only in non-oxidative hair dyes under EU Annex III, never broad cosmetic use
  • Skin sensitization potential typical of cationic xanthene dyes
  • Aquatic toxicity concerns from xanthene chromophore
