In short

Benzyl isoeugenol is the benzyl ether of isoeugenol. It has a faint, sweet carnation-spice odour and is used as a fixative in spicy florals.

What Benzyl Isoeugenol smells like

Benzyl isoeugenol has a faint, floral rose-carnation odour, in chemical references; other suppliers describe soft, spicy carnation and orange blossom with a balsamic character, milder and more diffusive than isoeugenol. It is described as an excellent fixative for floral compositions, particularly violet bases and ylang-ylang blends.

What makes Benzyl Isoeugenol distinctive

A carnation that whispers: a faint, balsamic rose-carnation used to fix florals rather than lead them.

How Benzyl Isoeugenol is used

Used as a fixative in floral compositions, particularly violet, ylang-ylang and carnation bases.

Typical role: fixative (slow to evaporate; helps a blend last and holds lighter notes).

How Benzyl Isoeugenol differs from similar materials

Isoeugenyl Acetate
Isoeugenyl acetate is a clearer, fruity-balsamic carnation; benzyl isoeugenol is fainter, a rose-carnation fixative.
Methyl Isoeugenol
Methyl isoeugenol is a clearer, mild clove-carnation; benzyl isoeugenol is fainter and more balsamic.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.

Formulation considerations

Check the IFRA position on isoeugenol and its derivatives for your product category. A solid; dissolve before use.

Safety and compliance

Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory report it as not meeting the GHS hazard criteria (1,583 of 1,623 reports). Unless it is harmonised, this is the notifiers' own classification, not a binding one.

This page is general information, not a safety assessment or a specification. Confirm identity, composition, IFRA status and allergen content from your supplier's documents for the lot you hold.
