Chemistry & Uses
Year of discovery :
Data not available.
Natural availability :
Cuminaldehyde can be extracted in its natural state from Cumin EO, as it represents 40% of its composition.
Isomerism :
The ortho and meta isomers isolated from Cuminaldehyde are not used in fine perfumery. Cuminaldehyde is a constitutional isomer of Anethole, which has a very different smell reminiscent of Star Anise EO.
Synthesis precursor :
Cuminaldehyde is the precursor to several raw materials. Its oxidation gives Cuminic Acid, the hydrogenation of the aldehyde function leads to Cuminic Alcohol and its total hydrogenation synthesizes Mayol with a smell of lily of the valley. It can also form a Schiff base with Methyl Anthranilate, with a fruity and more artificial smell, or a dimethyl acetal which also has an olfactory interest.
Synthesis route :
Cuminaldehyde synthesis is made by reduction of 4-Isopropylbenzoyl chloride or by formylation of cumene.
Stability :
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell
Most of the time, the occurrence of a benzenic cycle in a molecule causes a coloration of this molecule through time

Annexe I :
Some regulated synthetic ingredients are found in nature and in certain proportions in natural ingredients. This presence in nature has to be taken into account when calculating limits of use recommended by the IFRA. In case you do not know these concentrations, you can use the ones estimated by the IFRA. Here they are :
