CAS 54464-57-2 · Woody · Amber · IFRA restricted (fine fragrance max 20%)

Iso E Super is IFF's original OTNE, the smooth woody-amber molecule sitting under a huge share of modern perfumes. It is soft, velvety and oddly elusive: some people barely smell it, yet it makes everything around it feel bigger, smoother and longer-lasting.

What it smells like

Dry, velvety cedarwood with a soft amber warmth and a faint vetiver-like edge. Transparent rather than heavy, and very long-lasting on skin and fabric.

How perfumers use it

Perfumers use it generously as a woody backbone. It blends into almost any accord, lifts florals and citruses, and with Ambroxan and a clean musk forms the classic woody-amber skin scent. Because it is IFRA restricted, check the limit for your product category, especially at the high doses this material invites.

Blends well with: Ambroxan / Ambermor, Hedione, Galaxolide, Cedramber, Bergamot.
