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 is a residue from the distillation of coal tar bases, included when it contains more than 0.1% w/w benzene. EU Cosmetics Regulation 1223/2009 Annex II prohibits benzene at this threshold, and these coal tar residues are classified as CMR Category 1A under CLP Regulation (EC) 1272/2008. Coal tar distillation residues are known to contain PAHs, nitrogen heterocycles, and phenolic compounds in addition to benzene, creating a complex toxicological profile. The EU REACH registration notes severe hazards including carcinogenicity, and these residues are prohibited from cosmetic use.

Known concerns

  • Contains benzene >0.1% w/w — EU Annex II prohibited substance
  • CMR Category 1A carcinogen under CLP
  • Coal tar origin — multiple PAH and heterocyclic contaminants
  • Skin absorption and environmental persistence
  • Severe acute and chronic toxicity
