AMBER XTREME™ (IFF)

CAS: 476332-65-7

EC: 449-360-4

Chemical name: 2h-Indeno[4,5-B] Furan, Decahydro-2,2,6,6,7,8,8-Heptamethyl

Olfactory class: woody amber, dry and musky.

Olfactory profile

A very intense, diffusing, and tenacious amber-woody molecule. Key notes: dry, woody, musky amber with earthy nuances and a hint of camphorated notes; woodier and more impactful than Cashmeran® . Excellent for adding volume and lift to the base.

Performance & use in formula

• Power/Impact: Very high; great spread in the head and persistence in the slipstream.
• Substantivity on supports: > 1 week (textiles/leather).
• Typical usage level: trace amounts up to 0.5% of the concentrate (often 0.05–0.2% is sufficient for a booster effect).
• Role: Amber-woody booster, modern fixative for woody, fougère, amber, leather, and tobacco accords; also useful in floral and fruity fragrances to add body and depth.
