About

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

Naphazoline is an imidazoline derivative that acts as a sympathomimetic vasoconstrictor. Its pharmaceutical use in ophthalmic products means it is not permitted as a cosmetic active ingredient under EU regulations; cosmetic use would require specific CosIng authorization, which is not listed.

Known concerns

  • Pharmaceutical vasoconstrictor not approved for cosmetic use
  • Can cause systemic sympathomimetic effects if absorbed
  • Not listed in EU CosIng for cosmetic use
