About

A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Coal tar bases are complex mixtures of nitrogen-containing aromatic heterocycles including pyridine, quinoline, and aniline derivatives. IARC classifies coal tar as Group 1 carcinogen to humans. The conditional benzene flag adds further EU Annex II concern. EU Regulation 1223/2009 prohibits coal tar-derived substances in cosmetic products, and crude tar bases have no established safety profile for topical application. Industrial chemical only.

Known concerns

  • Coal tar origin — IARC Group 1 carcinogen
  • Contains quinoline and other confirmed animal/human carcinogens
  • Benzene >0.1% w/w — EU Annex II prohibited
  • Potential PAH and heavy metal contamination from coal source
  • No established cosmetic function or SCCS safety opinion
