In short
Rhodinyl acetate is a rose acetate related to citronellyl acetate. It has a fresh rose-bouquet odour with citrus and rose-leaf nuances and a long drydown.
What Rhodinyl Acetate smells like
JECFA, as published by PubChem, describes rhodinyl acetate as having a light, fresh, rose-like odour. Fraterworks calls it a rose bouquet note with nuances of citrus and rose leaves, darker and more leafy than other rose acetates such as citronellyl acetate, with a significantly longer drydown.

What makes Rhodinyl Acetate distinctive
A leafier, longer-lasting rose acetate than citronellyl acetate.
How Rhodinyl Acetate is used
Used in rose, muguet, geranium and citrus bases, and to carry a citronellyl acetate theme into the drydown.
Typical role: blender (smooths the joins between other materials); modifier (used in small amounts to change the character of a blend).
How Rhodinyl Acetate differs from similar materials
- Citronellyl Acetate
- Citronellyl acetate is a clean, fruity rose with pear; rhodinyl acetate is leafier and longer-lasting.
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
The IFRA Standards Library lists a Standard covering Rhodinyl Acetate:
- "Citronellyl acetate" — Restriction, 51st Amendment, published 2023-06
Limits differ by product category and are set out in the Standard itself; this page does not reproduce them. The list above reflects the library as read on 19 October 2026.
Hazard classification of the neat substance, as PubChem summarises it, read 26 October 2026. Companies notifying the ECHA C&L Inventory classify it (1,439 reports): H315 causes skin irritation (97.3% of reports); H411 toxic to aquatic life with long lasting effects (97.3% of reports); H319 causes serious eye irritation (89.4% of reports). Unless it is harmonised, this is the notifiers' own classification, not a binding one.
