About this material

RoastNote 235

RoastNote 235 is a high-impact roasted material that captures the dark warmth of toasted nuts, cocoa powder and browned crust.

Its compact profile can transform a smooth gourmand accord by introducing the slight dryness and aromatic tension that make a roasted effect feel convincing.

Beyond sweetness, it brings shadow and texture.

A trace can suggest cocoa husk, roasted grain or hazelnut skin, while a more deliberate treatment can create an assertive coffee, praline or toasted-wood signature.

Its particular luxury comes from contrast.

RoastNote 235 can set burnished, almost blackened detail against cream, vanilla or fruit, giving a composition the complexity of something caramelised, roasted and still warm rather than simply sweet.

Odour profile

The odour is intensely nutty and roasted, with cocoa-like, earthy and baked-potato nuances.

A dry, slightly powdery character gives the material depth, suggesting nut skins and the browned edge of a roasted accord rather than simple sugary sweetness.

At first encounter, the effect is concentrated and savoury, recalling freshly roasted kernels, dark crust and the dry shell of a hazelnut.

The impression is powerful, dry and immediately textural.

In careful dilution, more nuanced facets become visible: toasted hazelnut, cocoa powder, warm grain and a faint earthy smokiness.

These details make the material useful as a source of realism and depth rather than sweetness in its own right.

Using RoastNote 235 in perfumery

RoastNote 235 is useful in coffee, cocoa, nut, praline, tobacco and baked-gourmand accords.

It can also add a charred, savoury accent to leather, patchouli, smoky woods and dark amber constructions when used with particular restraint.

Within gourmand perfumery, it can turn a smooth vanilla or caramel accord into something more faceted, adding browned edges to praline, biscuit, coffee and cocoa themes.

It can also make nut effects feel less creamy and more freshly roasted.

Outside the gourmand palette, traces can introduce a charred shadow to tobacco, leather, patchouli and dark woods.

The material is most expressive when it appears as a precise detail, revealing itself gradually rather than dominating the fragrance.

Creative pairings

Explore RoastNote 235 with coffee materials, cocoa, hazelnut, maltol, vanillin, tonka effects, tobacco, patchouli, cedarwood, guaiacwood, labdanum and leather notes.

Careful dosing preserves its luxurious toasted detail and avoids overwhelming quieter materials.

Set it against milky, creamy or vanillic materials for dramatic contrast, or deepen its darker character with vetiver, guaiacwood, patchouli, labdanum and suede effects.

Fruity accents such as cherry or plum can create an especially decadent roasted-gourmand tension.

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.

Garden after rain

With leafy and root-like directions

Explore an earthy garden sketch by pairing the listed character with a green leaf or root direction. Keep those two options separate at first so you can distinguish a fresh soil idea from a denser, darker one.

Roots and timber

With dry and soft wood contrasts

Build an earthy wood study around a deliberately simple wood accord. Compare a dry outline with a smoother variation, noting which makes the material’s character easier to recognise and which turns the sketch into something new.

Rose in the ground

With a familiar rose accord

Set the earthy material against a clear rose reference for a flower-and-soil concept. Evaluate the contrast before adding sweetness or spice; the aim is to decide whether the earthy accent enriches your imagined scene.

Document scope and limitations

The supplementary documents currently available for this material are identified in this tab. Availability varies between materials.

Batch-specific certificates, analytical results and additional technical data are not guaranteed. They are supplied only where their availability is expressly confirmed in this tab or separately confirmed by us in writing.

Where provided, supplier IFRA documentation does not replace a comprehensive safety assessment or constitute approval of a finished formulation. Customers must consider their complete formulation and intended application.

Any linked IFRA standard is provided for reference and is not a batch-specific specification or analytical certificate for the material supplied.

Do not assume that documentation confirms a particular batch, residual constituent level, manufacturing process or analytical result unless it expressly states this.

The same limitations apply to allergen declarations, Certificates of Analysis (CoAs), technical data sheets, specifications, and other regulatory, analytical or compositional documents. These documents provide information only within their stated scope; they do not replace a comprehensive safety assessment or constitute approval of a finished formulation, nor do they guarantee suitability for a particular application. Customers must assess their complete formulation and intended use.

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.
