Chemistry & Uses
Uses in perfumery :
Para-Cresyl acetate can be used in the composition of a white or light floral accord for its animalic and floral note. Can also be used for animalic and leather notes.
Year of discovery :
Data not available.
Natural availability :
Cresolic compounds such as para-Cresyl acetate or para-Cresyl Phenyl acetate are the compounds that gives Ylang-Ylang Extra EO (and other ylang fractions) its animalic note, as they are present in trace amounts.
Isomerism :
Para-Cresyl acetate is the ester of Para-Cresol. Ortho-Cresyl acetate has a fruity smell, close to dried fruits, rather medicinal. On the other hand, meta-Cresyl acetate is similar to para-Cresyl acetate. Benzyl acetate is a constitutional isomer of para-Cresyl acetate, although these two isomers have a very different smell: Benzyl acetate has a very jasmine, fruity and heady smell, and is not animalic.
Synthesis precursor :
Para-Cresyl acetate is not a precursor to the synthesis of another compound of olfactory interest.
Synthesis route :
Para-Cresyl acetate results from the esterification of para-Cresol with acetic acid or acetic anhydride, catalysed by the presence of a strong acid such as concentrated sulfuric acid.
Stability :
acetates may form acetic acid through time. Para-Cresyl acetate is particularly unstable.
Other comments :
In comparision to para-Cresol, para-Cresyl acetate brings a more butyric and floral smell, when para-Cresol is more purely phenolic and has a slight almond touch.
Can contain traces of para-Cresol.
