Safety and compliance
- Status. No safety assessment is recorded for this formula, and this page does not say it is compliant for any use.
- IFRA Standards. The IFRA Standards Library covers 3 of its materials: Homofuraneol (Restriction: Ethyl and Methyl furaneol, Amendment 51); Benzaldehyde (Restriction: Benzaldehyde, Amendment 49); Coumarin (Restriction: Coumarin, Amendment 49).
- Skin sensitisation. EU-labelled fragrance allergens present as ingredients: Coumarin. Natural materials carry further allergens as constituents, declared from the supplier’s data, and Regulation (EU) 2023/1545 extends the list to be labelled on products placed on the EU market from 31 July 2026.

- Not covered. One ingredient is not matched to a material, so it is not in this summary.
