About

A cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Stoddard solvent (CAS 8052-41-3) is a petroleum distillate used as a dry cleaning solvent and degreaser. Like naphtha and ligroine, it is prohibited in cosmetic products when benzene content exceeds 0.1% w/w. This threshold reflects the EU's zero-tolerance approach to benzene in consumer products given its classified carcinogenicity and ability to penetrate skin. Contaminated Stoddard solvent has no place in cosmetic formulations.

Known concerns

  • EU Annex II — benzene contamination (>0.1% prohibited)
  • Known human carcinogen (benzene)
  • Prohibited industrial solvent
