About

A C8-rich aromatic hydrocarbon mixture from petroleum refining, flagged for benzene content that exceeds the regulatory limit for cosmetic ingredients and places it on the EU's banned substances list.

Aromatic hydrocarbon mixture dominated by C8 homologues (ethylbenzene, xylenes, trimethylbenzenes) sourced from catalytic reforming or cracking streams. Benzene content exceeding 0.1% w/w triggers prohibition under EU Annex II of Regulation 1223/2009; no concentration of this mixture can be considered safe in cosmetic formulations given the known threshold for benzene carcinogenicity.

Known concerns

  • Contains benzene >0.1% w/w — EU Annex II CMR Cat 1A carcinogen
  • Mixture composition varies by source, creating unpredictable dermal exposure profiles
  • Volatile components facilitate pulmonary and dermal absorption
