Composition notes

  • Key materials. Ambrettolide, Isoambrettolide, Helvetolide, Ambrette Seed Oil, Hedione HC
  • What makes it distinctive. A musk built on ambrette — a natural, fruity-winey musk — and its macrocyclic relatives rather than on polycyclic laundry musks.
  • Character. Refined, comforting and suitable for everyday wear close to the skin.
  • Concentration. 12–15%

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 5 of its materials: Exaltolide (Restriction: Cyclopentadecanolide, Amendment 49); Sandalore (Restriction: 5-(2,2,3-Trimethyl-3-cyclopentenyl)-3-methylpentan-2-ol, Amendment 49); Cashmeran (Restriction: 6,7-Dihydro-1,1,2,3,3-pentamethyl-4(5H)-indanone (DPMI), Amendment 49); Iso E Super (Restriction: 1-(1,2,3,4,5,6,7,8 Octahydro-2,3,8,8-tetramethyl-2-naphthalenyl) ethanone (OTNE), Amendment 49); Angelica Root Oil (Restriction: Angelica root oil, Amendment 49).
  • Phototoxicity. Angelica Root Oil is phototoxic; IFRA limits phototoxic materials in products left on skin exposed to sunlight.
  • 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.
