55

Safety score · 0–100

Moderate

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

A synthetic bicyclic ketone used purely as a fragrance ingredient in perfumes and cosmetics. It carries the typical scent-allergen risk profile of musk-style aroma chemicals rather than any active skincare benefit.

Skin benefits

  • Provides fragrance character in perfumes and scented cosmetics
  • Synthetic bicyclic ketone used at low fragrance concentrations
  • Stable, well-suited to leave-on and rinse-off formulas

Known concerns

  • Synthetic fragrance compounds can trigger allergic contact dermatitis in sensitive users
  • Limited public toxicology data beyond fragrance-industry assessments
  • May contribute to overall fragrance allergen load when undisclosed in 'parfum'
