CIVETONE Usage And Synthesis
Chemical Properties
CIVETONE is a colorless
liquid with warm, sensual, animalic musky odor and extreme tenacity. It is
themain odoriferous constituent of civet.Civetonewas formerly prepared bymultistep
syntheses, for example. Recently, newer processes using dimethyl
(Z)-9-octadecendioate as starting material have been described. This is cyclized
by a Dieckmann condensation either in liquid or in gaseous phase.
(Z)-9-Octadecendioic acid is available by microbial oxidation of oleic acid with
Candida tropicalis.
It is used in fine fragrance compositions for, for example, toiletries and body
care products.
Chemical Properties
Cycloheptadeca-9-en-1-one has an obnoxious animal-gland odor. It can be pleasant at extreme dilutions.
Occurrence
In civet (cis-form).
Uses
In perfumery.
Preparation
From aleuritic acid, the trans- form only; the cis- and trans-forms from ethyl-9-keto heptadecanedioate.
Definition
ChEBI: A macrocycle that is cycloheptadecanone with an unsaturation at position 9 (the 9Z-stereoisomer). It has been found in African Civets.
Aroma threshold values
Detection: 3 ppb
Safety Profile
A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes.
