Safety and compliance
- Status. Regulatory assessment pending. No formula-level safety assessment is documented yet, so this page does not say the formula is compliant for any use.
- IFRA Standards. The IFRA Standards Library covers 2 of its materials: alpha-Isomethyl Ionone (Methyl ionone, mixed isomers, Amendment 49); Cashmeran (Restriction: 6,7-Dihydro-1,1,2,3,3-pentamethyl-4(5H)-indanone (DPMI), Amendment 49).
- Skin sensitisation. EU-labelled fragrance allergens present as ingredients: alpha-Isomethyl ionone. 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.
