Residues (petroleum), butane splitter bottoms, if it contains > 0.1% w/w benzene

CAS 68478-12-6
5

Safety score · 0–100

Avoid

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

A butane splitter bottoms residue from petroleum refining, included when benzene exceeds 0.1% w/w — this heavy residue contains concentrated aromatic compounds and is prohibited in EU cosmetics.

This is a heavy bottom fraction from the butane splitter in petroleum refining, included when it contains more than 0.1% w/w benzene. The EU Cosmetics Regulation 1223/2009 Annex II prohibits benzene in cosmetic products at any concentration above this threshold, and this heavy residue stream is classified as CMR Category 1A under CLP Regulation (EC) 1272/2008. Refinery residues of this type represent complex mixtures of higher-boiling hydrocarbons and are not permitted as cosmetic ingredients in the EU under any formulation circumstances.

Known concerns

  • Contains benzene >0.1% w/w — EU Annex II prohibited substance
  • CMR Category 1A carcinogen under CLP
  • Heavy hydrocarbon residue — skin absorption potential
  • Environmental hazard
