About

Tetrahydro-6-nitroquinoxaline And Its Salts is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Tetrahydro-6-nitroquinoxaline is a heterocyclic aromatic compound containing a nitrated quinoxaline ring system. Nitro-substituted aromatic compounds are generally considered problematic in cosmetic formulations due to concerns about potential reduction to reactive intermediates and photosensitization. Under EU Regulation (EC) No 1223/2009 Annex II, nitro compounds in hair dye applications are generally restricted or prohibited. The compound is listed as a hair dye precursor in Annex II, prohibiting its use in cosmetic products in the EU regardless of concentration. Multiple CAS numbers reflect different salt forms, all sharing the core tetrahydro-nitroquinoxaline structure and regulatory restriction.

Known concerns

  • Prohibited in EU cosmetics (Annex II)
  • Hair dye precursor with nitro-group concerns
  • Potential photosensitization
