About
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
