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.
