About this material

Okoumal by Givaudan, also known as Woody Dioxolane is a synthetic fragrance molecule praised for its richness, warmth and longevity.

Okoumal delivers an elegant blend of woody, ambery, smoky tobacco, and musky tones.

At low use levels; 0.5 % to 1 % it instantly adds body and volume to compositions without overpowering them and at higher dosage (up to 4 %) intensifies richness and depth.

With a very low vapor pressure and high molecular weight, Okoumal is a true heart or base note and will linger for over a month on a blotter and/or fabric, providing excellent substantivity in both wet and dry applications.

According to Givaudan, it remains stable across pH levels and in form factors ranging from shampoo, soap, detergents to antiperspirants—rated highly in most tested conditions.

Ideal pairings include cedar derivatives, Patchouli and sandalwood molecules (e.g., Ebanol™), where it reinforces and enhances a woody-amber depth.

Okoumal is great for:

Amber, tobacco, and musk accords: It reinforces warm, smoky, earthy facets in Oriental, Chypre, Fougère, and leather bases.
Fixative power: Adds projection and longevity without heaviness.
Texture enhancing: Offers a “velvety” or “powdery” feel, making mature or leather-like woods more sophisticated and with a tobacco‑tinged softness.
Adding subtle sparkle: Ideal at low levels to lift woods with a soft sheen rather than overt brightness.

In summary; Okoumal is a high‑performance woody‑amber aroma chemical, beloved by perfumers for its ability to build warmth and complexity, act as a fixative, and improve texture in a wide variety of fragrance structures.

Its blend of tobacco-like softness and musky amber richness makes it a dependable choice for durable, elegant and sophisticated compositions.

This molecular reference matches the catalogue’s recorded CAS and formula. It does not confirm the supplied grade, purity, stereochemistry, isomer proportions, composition, impurities or unlisted constituents.

Fragrance allergen reference

Generic regulatory reference only. This is not a supplier allergen declaration, measured composition, allergen-free claim or finished-product labelling assessment.

Raw-material reference based on recorded CAS numbers. A CAS match identifies a reference entry; it does not verify the supplied grade, composition, purity or finished-product compliance. Naturals, bases and mixtures require composition review.

No direct listed-entry CAS match in this jurisdiction’s held reference set. This does not mean the material is allergen-free. Constituents, grouped entries and natural-material composition may require further review.

Finished-cosmetic declaration thresholds: greater than 0.001% leave-on; greater than 0.01% rinse-off. Apply the current target-market rules to the actual complete formulation; no concentration is inferred here.

Creative ideas to explore

Creative directions, not tested formulas.

Woods in daylight

With bergamot and a crisp citrus opening

Explore 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 direction

Set 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 accord

Try 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.

Customer responsibility

These limitations apply to reliance on all documentation supplied, including IFRA information, allergen declarations, Certificates of Analysis (CoAs), technical data sheets, specifications and other supporting documents.

Perfume Extract is solely a reseller of this product and is not an agent, official distributor, or affiliated in any way with the manufacturer.

Customers are responsible for determining whether the material and available documentation meet their requirements before purchase, and for assessing the safety and compliance of their finished products.

We do not provide formulation instructions, formulation consultancy or confirmation of suitability at a particular concentration or for a particular application.

Producer identity, detailed sourcing and processing information are not disclosed beyond the information published in the product listing.

Please read our Documentation Supply Policy alongside the product specification and available documentation.

Synonyms, alternative names, CAS/EC references, botanical names, manufacturer references and external links may describe a substance or material family generally. They should not, on their own, be taken as confirmation of the supplied material’s producer, geographical origin, manufacturing process, grade, purity, constituent levels or batch characteristics.

In particular, a synonym or reference must not be used to infer that a material is free from a particular constituent, meets a numerical specification, or is suitable for a particular application or concentration.

IFRA information, allergen declarations, Certificates of Analysis (CoAs), technical data sheets and other supporting documents apply only within their expressly stated scope. A general specification or reference document is not a batch-specific analytical result unless it expressly identifies the relevant batch.

If information appears inconsistent, or a particular characteristic is essential to your purchase, contact us for written clarification before ordering. Do not resolve discrepancies by assuming that a synonym, external reference or document for another grade applies to the material supplied.

We do not confirm characteristics beyond those expressly supported by the applicable product specification or our written confirmation. Customers remain responsible for assessing their complete formulation and intended application.
