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 8 of its materials: Grapefruit Oil (Expressed) (Restriction: Grapefruit oil expressed, Amendment 49); Benzyl Salicylate (Restriction: Benzyl salicylate, Amendment 49); Citronellol (Restriction: Citronellol, Amendment 49); Citronellyl Acetate (Restriction: Citronellyl acetate, Amendment 51); Geraniol (Restriction: Geraniol, Amendment 51); Liffarome (Restriction: cis-3-Hexenyl methyl carbonate, Amendment 51); Rhodinyl Acetate (Restriction: Citronellyl acetate, Amendment 51); beta-Damascone (Restriction: Rose ketones, Amendment 49).
  • Phototoxicity. Grapefruit Oil (Expressed) 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, Geraniol. 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.
