In short
Mimosal is a dsm-firmenich aldehyde with an intense green muguet note and a mimosa-like powdery side. It was made to fill part of the gap left by Lilial and Lyral.
What Mimosal smells like
dsm-firmenich describes Mimosal as a synthetic molecule with an intense green muguet note, a soft anisic facet and a fresh cyclamen undertone, giving an impressive clean and long-lasting effect; its descriptors are muguet, aldehydic and mimosa. Fraterworks describes it as powerfully aldehydic with soft powdery floral notes and a watery aspect, crossing between muguet and mimosa, and as one of the materials designed after the bans on Lilial and Lyral.

What makes Mimosal distinctive
A muguet aldehyde with a powdery mimosa side.
How Mimosal is used
Used in muguet and floral accords, where it gives a clean, long-lasting effect.
Typical role: modifier (used in small amounts to change the character of a blend).
How Mimosal differs from similar materials
- Lilial
- Both are muguet aldehydes; Mimosal was designed partly to replace Lilial, and adds a powdery mimosa side and a soft anisic facet. (compared directly by a cited source)

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 (15 reports): H315 causes skin irritation (100% of reports); H317 may cause an allergic skin reaction (100% of reports); H411 toxic to aquatic life with long lasting effects (100% of reports). A skin sensitiser classification concerns handling the neat material and the dose in a finished product; the IFRA Standards, where they apply, set the limits. 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.
