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 one of its materials: Musk Ketone (Specification: Musk ketone, Amendment 45).
- Skin sensitisation. None of the EU’s long-standing named fragrance allergens is an ingredient in its own right. 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.
- Product category. Limits depend on the product: fine fragrance, leave-on and rinse-off products have different IFRA categories, and each Standard sets its own figure for each.
- Not covered. 7 ingredients are not matched to a material, so they are not in this summary.
