Other names :
4-propan-2-ylbenzaldehyde ; Cuminaldehyde ; 4-isopropyl benzaldehyde ; Cumaldehyde ; Cuminal ; Cuminic aldehyde
Volatility :
Head
Uses in perfumery :
Cuminaldehyde is used in leather, spicy notes, in heavy and spicy flower accords (e. g. carnation), in oriental and woody accords and for sweaty notes. Used as a replacor for Cumin EO, in which it is found at about 30% of the composition.
Natural availability :
Cuminaldehyde can be extracted in its natural state from Cumin EO, as it represents 40% of its composition.
Year of discovery :
Data not available.

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

Synthesis route :
Cuminaldehyde synthesis is made by reduction of 4-Isopropylbenzoyl chloride or by formylation of cumene.
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.
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.

- Comments :
- This material should not be used as a fragrance ingredient. The level of Benzene has to be kept as low as practicable and should never exceed 1 ppm in the fragrance compound/mixture or fragrance oil. Since the introduction of the original Restriction on the use of Benzene by IFRA in 1988, there have been significant changes in manufacturing practices that permit the reduction of the maximum permitted level of this substance. These include use of technological improvements allowing replacement of this solvent for the extraction of fragrance materials and in eliminating its presence as an impurity in alternative extraction solvents.
