Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

Xylometazoline (inn) And Its Salts is a cosmetic ingredient. Exercise caution due to limited available safety data.

Xylometazoline is an alpha-adrenergic agonist used as a topical nasal decongestant. Its inclusion in EU Annex III (restricted substances) at concentrations >=0.1% reflects concerns about its sympathomimetic pharmacological activity. While permitted at lower concentrations in some cosmetic contexts, the regulatory threshold is set to prevent pharmacological effects that would classify the product differently from conventional cosmetics.

Known concerns

  • EU Annex III restricted at >=0.1%
  • Pharmacologically active sympathomimetic
  • Potential for vasoconstrictive effects
