Other names :
2-[1-(3,3-dimethylcyclohexyl)ethoxy]-2-methylpropyl propionate ; Herbactolide
Volatility :
Base
Uses in perfumery :
Helvetolide is used in all kinds of perfumes (but espacially in fine fragrance because of its price) to bring a heady pear note and an Ambrette Seeds Absolute base note. It can be used as a fixative, with no cheap sub-effect. It is basically used as Musk T®, but brings more volume and tenacity to the fragrance.
Natural availability :
Helvetolide® does not exist on a natural state. It can't be extracted from a plant.
Year of discovery :
Discovered in 1990 by chemists Giersch and Schulte-Este.
'Helvetolide®' trademark has been published and protected by Firmenich SA since 30/04/1995 (brand N°636238).

Synthesis route :
Data not available.
Synthesis precursor :
Helvetolide® can be used to synthesize Romandolide®, which is more powerful. This synthesis consists in replacing the dimethyl groupement of the ether function of Helvetolide®, by a carbonyle function, forming an ester.
Isomerism :
Helvetolide® used in perfumery is a mix of two isomers, due to the presence of two asymmetric carbons inside the molecule. The first one is dextrorotatory Helvetolide® (+), less floral but more musky than the other isomer. This is why it is often preferred as the other isomers, and sometimes used alone, isolated from levorotatory Helvetolide® (-).
