About this material
Orivone by IFF is a masterfully crafted ingredient that captures the refined elegance of orris with exceptional strength and diffusion.
Instantly recognisable, its aroma unfolds with a striking camphoraceous lift, grounded by an earthy, root-like depth that closely echoes the character of natural orris root.
The profile is distinctly dry, lending a sophisticated, powdery restraint that elevates compositions without overwhelming them.
Highly economical in use, Orivone delivers remarkable impact even at very low concentrations, making it a prized tool for perfumers seeking both performance and precision.
Its versatility shines in formulation, where it harmonises effortlessly with ionones, lavandin oil, and a wide range of complementary materials.
Particularly compelling when paired with earthy, mossy accords, Orivone enhances depth and texture, adding a refined, velvety dryness that brings balance and complexity to both modern and classic fragrance structures.
A powerful yet elegant building block, it is an essential addition for creating compositions with lasting presence and understated luxury.

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). For more details see chapter 1 of the Guidance for the use of IFRA Standards.

Creative ideas to explore
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.
Petals on timber
With rose and a clear floral accordTry a flower-and-wood study in which both subjects remain recognisable. Compare the floral reference with the woody variation through the evaluation, noting whether the wood forms a useful backdrop or becomes the centre of the idea.
