About

Petrichloral (INN) is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Petrichloral is an INN-listed compound historically investigated as a sedating and hypnotic agent. It is a chloral derivative related to pharmaceutical sedatives. As a pharmacologically active substance targeting the central nervous system, it has no place in cosmetic formulations. EU cosmetics regulation prohibits pharmaceutical substances in cosmetic products. Any cosmetic presence would be entirely inappropriate and likely accidental.

Known concerns

  • Pharmaceutical drug substance, not cosmetic
  • CNS depressant activity makes it unsafe for topical use
  • No cosmetic safety assessment exists
