Composition notes

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 13 of its materials: alpha-Isomethyl Ionone (Methyl ionone, mixed isomers, Amendment 49); Benzyl Salicylate (Restriction: Benzyl salicylate, Amendment 49); Sandalore (Restriction: 5-(2,2,3-Trimethyl-3-cyclopentenyl)-3-methylpentan-2-ol, Amendment 49); Citronellol (Restriction: Citronellol, Amendment 49); Vetiveryl Acetate (Restriction: Acetylated Vetiver oil, Amendment 49); Ylang Ylang Oil (Restriction: Ylang ylang extracts, Amendment 49); Exaltolide (Restriction: Cyclopentadecanolide, Amendment 49); Hydroxycitronellal (Restriction: Hydroxycitronellal, Amendment 51); Lemon Oil (Cold-Pressed) (Restriction: Lemon oil cold pressed, Amendment 49); Coumarin (Restriction: Coumarin, Amendment 49); Geraniol (Restriction: Geraniol, Amendment 51); Jasmine Absolute (Grandiflorum) (Restriction: Jasmine absolute (grandiflorum), Amendment 49); Eugenol (Restriction: Eugenol, Amendment 51).
  • Phototoxicity. Lemon Oil (Cold-Pressed) is phototoxic; IFRA limits phototoxic materials in products left on skin exposed to sunlight.
  • Skin sensitisation. EU-labelled fragrance allergens present as ingredients: Benzyl salicylate, Citronellol, Coumarin, Eugenol, Geraniol, Hydroxycitronellal, 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.
