About this material

Aldehyde C9 (Nonanal)

Aldehyde C9, also known as Nonanal, is an extremely versatile aldehyde that is commonly used in modern perfumery.

It is a highly valued saturated aliphatic aldehyde that brings a unique dimension to fragrance creation.

Less citrusy and more refined, it reveals a delicate blend of waxy cucumber and soft rose facets; delivering a fresh, clean character when used in the right dilution.

Widely used in fine fragrance formulations, this aldehyde adds brilliance and elegance, especially in trace amounts.

It provides very natural ‘flower-wax’ or ‘petal’ notes and gives tremendous ‘lift’ to a perfume, making it ideal for floral compositions like Rose, Lily, Peony, Orris, Jasmine, and Tuberose.

It frequently features in aldehydic bases that enhance top notes with a radiant, airy quality.

Its pleasant, fatty, rose-type odour makes it a prized component in light floral creations. Due to its volatility, only small amounts are needed to achieve a powerful impact.

Whether you’re building a bright floral bouquet or adding nuance to a fresh accord, this aldehyde offers perfumers a tool of subtle sophistication and dynamic lift.

Reference data checked 2026-10-27.

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.

European Union / Northern Ireland

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.

Documentation Supply Policy

IFRA formulation guide

Generic reference only — not an IFRA certificate, compliance decision or use recommendation. The Responsible Person and qualified safety assessor must assess the actual finished formula using current applicable IFRA Standards, supplementary documentation where available and the CPSR.

Source: 51st Amendment overview, held source checked 2026-10-21. Bundle 2026-10-27. Individual Standards prevail over the overview.

No direct IFRA overview entry matched the recorded CAS in this held dataset. This does not mean unrestricted use, absence of relevant Standards or compliance. Constituent restrictions may still apply.

Creative ideas to explore

Creative directions, not tested formulas.

Polished petals

With rose and soft floral notes

Explore an aldehydic floral silhouette around a simple rose accord. Compare the opening and later impression with an unchanged floral reference; decide whether the effect feels airy, waxy or abstract before adding further complexity.

Citrus in white

With bergamot and a musk direction

Build a study around citrus brightness and a restrained musk backdrop. Let the aldehydic material be the changing variable, then note whether it supports the peel impression or takes the sketch towards a more abstract clean accord.

A softer frame

With sandalwood and powdery notes

Set the listed aldehydic character against a soft wood or powder direction. Compare the balance through the evaluation rather than judging only the first impression, and keep any successful version simple enough to understand what changed.

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.
