About this material

Isophytol is a specialist aroma-chemical raw material with a clear appearance and a notably discreet odour profile.

Unlike highly expressive fragrance ingredients selected for an immediately recognisable scent, Isophytol is better understood as a technically focused material for controlled formulation, synthesis and professional product development.

Its minimal aromatic presence makes it relevant where formulators require a material that does not impose a strong floral, fruity, woody or spicy signature upon the surrounding composition.

Odour profile

The supplied Isophytol is described as having no noticeable odour.

It should therefore not be presented as a conventional character ingredient or selected for the purpose of creating a strong fragrance note.

Its value lies in its comparatively neutral sensory profile and specialist chemical identity.

This distinguishes it from materials designed primarily to provide top, heart or base-note impact.

Using Isophytol in formulation

Isophytol may be considered for specialist technical applications, laboratory work and controlled formulation development where its particular chemical properties are required.

It can be useful when a formulator specifically needs Isophytol while wishing to avoid the strong aromatic interference associated with conventional perfume ingredients.

Using Isophytol as a fixative

Within fragrance development, Isophytol may be evaluated as a discreet fixative and background-support material.

Its minimal odour profile makes it particularly useful when greater persistence and continuity are required without introducing a prominent floral, fruity, woody or spicy character.

Rather than creating an obvious note of its own, it may help to anchor more volatile materials, soften transitions between the opening and drydown and support the lasting diffusion of the overall accord.

This can be especially valuable in delicate floral, green, tea-inspired, herbal and modern woody compositions where a more assertive fixative could alter the intended character.

Fixative performance and its influence upon diffusion will depend upon the complete formula, concentration and surrounding materials.

Isophytol should therefore be introduced incrementally, assessed in dilution and evaluated throughout the full drydown before the final level is established.

This is a material for informed professional selection.

Customers should assess its suitability according to the intended formulation, technical objective and applicable regulatory requirements rather than purchasing it solely for an expected fragrance effect.

A considered technical material

For professional formulators, Isophytol offers a clean and technically refined raw-material option.

Its inclusion in a formulation should be deliberate and based upon the material’s functional relevance, supported by appropriate testing and review of the available safety documentation.

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.

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.
