About

Carbon tetrachloride is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Carbon Tetrachloride (CCl4) is a dense, non-flammable chlorinated hydrocarbon historically used as a cleaning solvent and refrigerant. It is classified as a Category 2 probable human carcinogen (IARC Group 2A), a Category 3 acute toxicant (H301, H311, H331), and an ozone-depleting substance under the Montreal Protocol. The EU Cosmetics Regulation Annex II explicitly prohibits carbon tetrachloride from cosmetic products. No safe use level can be established given its severe toxicity profile.

Known concerns

  • EU Annex II prohibited substance
  • Category 2 probable carcinogen (IARC 2A)
  • Category 2 acute oral, dermal, inhalation toxicant (H301/H311/H331)
