In short
Phenylethyl benzoate is an ester of phenylethyl alcohol and benzoic acid. It has a faint, rosy-balsamic and honeyed odour.
What Phenylethyl Benzoate smells like
Phenylethyl benzoate is sweet, rose-like and honey-like, in ChemicalBook's description, and is used in trace amounts to fix honey and fruit flavours. In perfumery it is mainly a fixative and a blender for the heavier part of a fragrance, in carnation, neroli, rose and oriental bases. Parchem's specification gives soft rose, balsam, honey and floral.

What makes Phenylethyl Benzoate distinctive
A quiet rose-honey fixative, blending the heavy end of a floral rather than leading it.
How Phenylethyl Benzoate is used
Used as a fixative and blender in carnation, neroli, rose and oriental bases, and in traces in honey and fruit flavours.
Typical role: fixative (slow to evaporate; helps a blend last and holds lighter notes); blender (smooths the joins between other materials).
How Phenylethyl Benzoate differs from similar materials
- Phenylethyl Cinnamate
- The cinnamate is a heavier, sweeter balsamic rose; the benzoate leans more towards honey.
- Phenylethyl Alcohol
- Phenylethyl alcohol is the light, fresh rose; its benzoate ester is a faint, tenacious rose-honey fixative.
- Benzophenone
- Both are faint fixatives for the heavy end of a floral; benzophenone leans towards geranium, phenylethyl benzoate towards honey.
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.

Safety and compliance
Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (150 reports): H411 toxic to aquatic life with long lasting effects (17.3% of reports). 124 of the reports find it does not meet the hazard criteria. Unless it is harmonised, this is the notifiers' own classification, not a binding one.
