Chemistry & Uses
Uses in perfumery :
Bourgeonal™ is used in all types of perfumery, in floral-aldehydic, green notes. Often used for its stability in soap and detergent bases, in addition to alcoholic perfumery.
Year of discovery :
1959
Natural availability :
Bourgeonal™ is not available in its natural state.
Isomerism :
The meta and ortho isomers of Bourgeonal™ are not used in perfumery. Cyclamen Aldehyde is a positional isomer of Bourgeonal™. However, its smell is quite different, as it is more marine. Both have an aldehydic and floral-white flowers smell.
Synthesis precursor :
Bourgeonal™ forms a Schiff base by reaction with Methyl Anthranilate or Indole for example.
Synthesis route :
Bourgeonal™ can be synthesized from 4-tert-Butyl benzaldehyde by an aldol reaction with Acetaldehyde. The intermediate product that is obtained is 4-tert-Butyl Cinnamaldehyde. A catalytic hydrogenation converts this intermediate into Bourgeonal™. Another synthetic route reacts 4-tert-Butyl benzene with acrolein diacetate in the presence of a Lewis acid. Then, the intermediate product is subjected to a saponification.
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
Exclusively stable in fabric conditioners, shampoos and hair conditioners.
