Avoid

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

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

This coal tar-derived base fraction is obtained from the distillation of coal tar, with the benzene threshold qualifier (>0.1% w/w) triggering prohibition under EU Cosmetics Regulation 1223/2009 Annex II. Coal tar bases contain complex nitrogen-containing aromatic compounds including anilines and toluidine derivatives, which raise additional carcinogenic concerns beyond benzene itself. These substances are classified as CMR Category 1A/1B under CLP Regulation (EC) 1272/2008. The REACH registration dossier notes severe hazards including carcinogenicity, mutagenicity, and reprotoxicity, and they are prohibited from all cosmetic uses in the EU.

Known concerns

  • Contains benzene >0.1% w/w — EU Annex II prohibited substance
  • CMR Category 1A carcinogen under CLP
  • Coal tar origin — PAH and aniline co-contaminants
  • Severe skin, eye, and respiratory hazard
  • Environmental persistence and aquatic toxicity
