About 7-Ethoxy-4-methylcoumarin, when used as a fragrance ingredient
A coumarin derivative with reduced but still significant photosensitisation risk, regulated under EU Annex III and IFRA guidelines for fragrance allergen use.
Detailed Analysis
7-Ethoxy-4-methylcoumarin is a 7-alkoxy-substituted coumarin used as a fragrance ingredient. While alkoxy substitution reduces photosensitising activity compared to unsubstituted coumarin, it is still listed in EU Annex III as a restricted fragrance allergen. IFRA recommends maximum use levels (approximately 15 ppm in various categories), and the compound requires declaration on ingredient labels above threshold due to its coumarin-related concerns.
Known Concerns
- ⚠ Residual coumarin-related photosensitisation potential
- ⚠ EU Annex III restricted fragrance allergen
- ⚠ IFRA guidelines restrict use levels
Safety Score
