Safety score · 0–100

Avoid

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

A petroleum naphtha fraction prohibited in EU cosmetics whenever its benzene content exceeds 0.1 percent. At that purity it is a known carcinogen, and compliant formulations use only purified solvents.

Skin benefits

  • Industrial petroleum stream with no legitimate cosmetic benefit at this purity
  • Refined fractions can be used as solvents only if benzene is below threshold

Known concerns

  • Benzene above 0.1% triggers EU CMR Category 1A classification
  • Listed in EU Annex II as prohibited in cosmetics when above the benzene threshold
  • Known human carcinogen and bone-marrow toxicant
  • No safe consumer-use level
