About

Leucinocaine is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Leucinocaine is a local anaesthetic compound with structural similarities to both lidocaine and procaine. The EU CosIng database does not list leucinocaine as a permitted cosmetic ingredient, and no SCCS opinion or CIR safety assessment is available. Local anaesthetics in cosmetic products raise concerns about systemic absorption, sensitisation, and methaemoglobin formation. Use in cosmetic formulations is not supported under current EU regulatory frameworks.

Skin benefits

  • Topical anaesthetic effect could reduce skin sensitivity

Known concerns

  • No EU CosIng entry as permitted cosmetic ingredient
  • Local anaesthetics in cosmetics raise sensitisation concerns
  • Insufficient safety data for cosmetic use
