Safety score · 0–100

Moderate

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

A coumarin ether derivative bearing a geraniol side chain, combining coumarin's characteristic sweet Tonka bean aroma with citrus-floral geraniol notes.

This geraniol-coupled coumarin ether falls under EU allergen declaration requirements when present above 0.01% in leave-on products (Article 19 Regulation (EC) 1223/2009). Coumarin itself is listed in Annex III/358 with maximum concentration limits in several product categories. The geraniol moiety additionally triggers allergen labeling requirements under Commission Regulation (EU) 2023/1545 amending Annex III.

Known concerns

  • EU allergen declaration required (geraniol component)
  • Coumarin derivative — may fall under Annex III coumarin restrictions in certain product types
  • Sensitization potential as with all furanocoumarin-related structures
