Chemistry & Uses
Uses in perfumery :
Allyl Cyclohexyl Propionate is used in fruity notes of pineapple to bring a tasty, sweet, natural note and acidity of the fruit. It is more commonly used in exotic fruits notes and in chamomille reconstitutions.
Year of discovery :
Data not available.
Natural availability :
Allyl Cyclohexyl Propionate is not reported as found in nature. It can't be extracted and used as natural.
Isomerism :
Allyl Cyclohexyl Propionate is a constitutional isomer of Isobornyl acetate and Terpenyl acetate among others, but they do not have the same smell as ACHP.
Synthesis precursor :
Allyl Cyclohexyl Propionate is not used for the synthesis of another compound of olfactive interest.
Synthesis route :
Allyl Cyclohexyl Propionate is synthesized on a synthetical way in two steps, from Cinnamic Acid. The first step is a catalytic hydrogenation of the acid, at very high temperature (over 200°C), using a catalyst as palladium. The second step is an esterification involving the intermediary product, cyclohexyl propionic acid, and allyl alcohol, i.e. 2-propenol. This reaction is heated and uses an acidic catalysor as concentrated sulfuric acid.
Stability :
Esters may form their corresponding acid in stability
Other comments :
In comparision to other notes of pineapple as Ethyl Butyrate, Allyl Caproate and Allyl Amyl Glycolate for example, CHPA brings a tasty and natural fruit note.

Specified ingredients: notes
According to the IFRA Specification Standard of Allyl esters, Allyl esters should only be used when the level of free Allylalcohol in the ester is less than 0.1%. This recommendation is based on the delayed irritant potential of Allylalcohol.
Please also refer to the IFRA Specification Standard Allyl esters.
