About this material

ISO E Super TOCO is a modern masterpiece of fragrance chemistry; a luxurious, woody-amber molecule prized for its smooth, velvety, sophisticated scent and remarkable versatility.

This enhanced version of the iconic Iso E Super; manufactured by IFF results in a beautifully consistent ingredient that performs impeccably across fine fragrances, colognes and scented body products.

Its scent is velvety, musky, and amber-woody, with an almost magnetic softness that lingers on the skin.

While subtle on its own, ISO E Super TOCO reveals its full character in blends; adding depth, warmth, and diffusion to compositions and enhancing other notes without overpowering them.

A true cornerstone of modern perfumery, Iso E Super has been used in iconic creations such as Dior Sauvage and was revolutionized by Escentric Molecules’ Molecule 01.

For the untrained nose, ISO E Super TOCO may be barely perceptible; yet it leaves an unmistakable trail of sophistication that lingers long after the first impression.

While some believe ISO E Super has pheromonal qualities, this remains anecdotal; unlike Hedione, whose sensual effects are supported by research.

For perfumers seeking even greater impact, related materials include Timbersilk and Sylvamber, both offering intensified woody-amber characters that are based on the same DNA.

Tocopherol helps maintain the integrity of the fragrance molecule during storage, processing and in challenging formulation matrices (e.g. heat, light, air exposure).

Proividing excellent stability and with improved longevity, perfumers using ISO E Super TOCO can expect the same olfactive beauty as the original; but with greater confidence in its resistance to oxidation, discoloration, and degradation over time. This enhanced reliability makes it a highly sought-after choice among perfumers dedicated to crafting exceptional, long-lasting creations of uncompromising quality.

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.

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.

Nothing in this information excludes or restricts liability or statutory rights that cannot lawfully be excluded or restricted.
