Naphtha (petroleum), catalytic dewaxed, if it contains > 0.1% w/w benzene

CAS 64742-66-1

Safety score · 0–100

Avoid

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

A dewaxed petroleum naphtha that may contain benzene above the regulated 0.1% threshold, rendering it prohibited for use in cosmetic products under EU Regulation (EC) No 1223/2009.

Produced by catalytic dewaxing of petroleum feedstocks, this naphtha stream is a complex mixture of C5–C12 hydrocarbons. The benzene content conditional trigger places it under the same EU carcinogen restrictions as other benzene-containing petroleum streams. As a hydrocarbon mixture it poses aspiration pneumonia risk if ingested, and aromatic components are potential skin sensitizers.

Known concerns

  • Contains >0.1% benzene — EU Annex II restricted CMR substance
  • Category 1A carcinogen under CLP Regulation (EC) No 1272/2008
  • Aspiration hazard from petroleum hydrocarbon distillates
  • Skin irritant potential
