Avoid

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

A light straight-run petroleum naphtha from atmospheric distillation, included specifically when benzene exceeds 0.1% w/w — benzene at this level triggers prohibition in EU cosmetics with no exceptions.

This is a straight-run light naphtha obtained directly from atmospheric distillation of crude oil, included in this list when it contains more than 0.1% w/w benzene. EU Regulation 1223/2009 Annex II entry 1682 prohibits benzene in cosmetic products, and this threshold is the operative trigger. Classified as a CMR Category 1A carcinogen under CLP Regulation (EC) 1272/2008, this substance has no authorized use in cosmetic products in the EU. Straight-run naphthas are complex mixtures that retain benzene from the original crude oil fractionation.

Known concerns

  • Contains benzene >0.1% w/w — EU Annex II prohibited substance
  • CMR Category 1A carcinogen under CLP
  • Flammable liquid with aspiration hazard
  • Contains mixed hydrocarbons with variable toxicological profile
