About this material
Norlimbanol Dextro
Norlimbanol Dextro Firmenich is a highly refined, pure isomer of the classic Norlimbanol molecule, developed as a standout woody–amber ingredient for high-end perfumery.
It provides a powerful, dry woody note with creamy amber warmth and subtle musky nuances.
A diffusive woody–amber amplifier, enhancing top-to-base presence across fragrance pyramids—adds elegant musk, creamy warmth, and vibrant dry woodiness.
Suitable for fine fragrances, shampoos, shower gels, soaps, detergents, softeners, cleaners and candles—featured across all fragrance layers (top, heart and base)
In fine fragrance formulas, average concentrations are extremely low—0.00003 to 0.0029%, with maximum up to 0.017%
Start low (0.1–1% in the formula), build slowly—you can dial up presence without overpowering. A little goes a very very long way! It’s super strong; yet elegant with proper dosing.
Firmly rooted in Firmenich’s heritage of synthetic woody molecules—starting with Z11™ (1961) and Polysantol® (1985)—Norlimbanol Dextro is positioned as their latest woody-amber flagship material.
Officially launched around 2018 as part of its “white biotech” innovation portfolio.
It’s the absolute pure key isomer of Norlimbanol, optimised for maximum clarity and nuance.
Highly diffusive, stable, long-lasting across diverse product formats.
Overall, Norlimbanol Dextro is a premium woody‑amber powerhouse—a modern classic in perfumery with both technical sophistication and creative flair.
An inspiring addition to every perfumer’s palette!

CAS numbers (comment): The scope of this Standard includes, but is not limited to the CAS number(s) indicated above; any other CAS number(s) used to identify this fragrance ingredient should be considered in scope as well.
Contributions from other sources: None to consider
Flavor use consideration: Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org).

Creative directions, not tested formulas.Woods in daylight
With bergamot and a crisp citrus openingExplore a spare wood structure with citrus providing the opening contrast. Compare a brighter version with the wood reference and follow how the outline changes, keeping the later impression as important as the first moment.
A softer grain
With sandalwood and a musk directionSet the woody material beside a softer wood reference, then compare a restrained musk variation. Decide whether your concept needs creamy texture, dry definition or more space between its parts before expanding the accord.
