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. |
Definition | ChEBI: A macrocycle that is cycloheptadecanone with an unsaturation at position 9 (the 9Z-stereoisomer). It has been found in African Civets. |
Preparation | From aleuritic acid, the trans- form only; the cis- and trans-forms from ethyl-9-keto heptadecanedioate. |
Aroma threshold values | Detection: 3 ppb |
Safety Profile | A skin irritant. When heated to decomposition it emits acrid smoke and irritating fumes. |
