Safety score · 0–100

Avoid

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

Unrefined heavy residue from atmospheric distillation of crude oil. Rich in polycyclic aromatic hydrocarbons, this is a fuel and asphalt feedstock, not a cosmetic-grade ingredient, with carcinogenicity concerns.

Skin benefits

  • Cheap petroleum-derived heavy residue with film-forming bulk
  • Historically used as crude lubricant base or asphalt feedstock

Known concerns

  • Unrefined heavy atmospheric tower residue typically contains 5%+ polycyclic aromatic hydrocarbons (PAHs)
  • PAH content includes known IARC carcinogens unless severely solvent-refined
  • Not appropriate or approved for cosmetic skin contact
  • Potential for skin irritation and long-term carcinogenicity with chronic exposure
