Dihydromyrcenol Chemical Properties,Uses,Production
Chemical Properties
Dihydromyrcenol is a colorless liquid with a fresh citrus-like odor and a lavender note. It is obtained from 3,7-dimethyl-1,6- octadiene (citronellene), the pyrolysis product of cis-pinane and can be prepared by three different processes: (i) by addition of hydrogen chloride and subsequent hydrolysis of the resulting 2,6-dimethyl-2-chloro-7-octene; or (ii) by addition of formic acid and subsequent saponification of the resulting dihydromycrenyl formate; or (iii) by direct hydroxylation with 60–80% sulfuric acid.Dihydromyrcenol is used in fine fragrances as well as in soap and detergent perfumes for fresh lime and citrus-like floral notes.
Occurrence
Found in the leaf oils of Barosma venusta and in the oil of hops (Gildemeister & Hoffman, 1960)
Uses
Dihydromyrcenol is used in the fragrance industry for its fresh lime and citrus-like odor.
Dihydromyrcenol is a fragrance ingredient used in cosmetics, fine fragrances, shampoos, toilet soaps, and other toiletries as well as in non-cosmetic products such as household cleaners and detergents. Its worldwide use is greater than >1000 metric tons per year (IFRA, 2004). A colorless, somewhat viscous liquid that is a mixture of approximately 50% 2,6-dimethyl-7-octen-2-ol and 50% 2,6-dimethyl-7-octen-2-yl formate. It has apparently not been reported to occur in nature.
Definition
ChEBI: A monoterpenoid that is oct-7-en-2-ol substituted by methyl groups at positions 2 and 6 respectively.
Preparation
Dihydromyrcenol is prepared by adding hydrogen chloride to myrcene followed by hydrolysis under mild conditions.(Bedoukian, 1967)
General Description
Methoxycarbonylation of dihydromyrcenol catalyzed by [PdCl2(PPh3)2]-SnCl2·2H2O-2PPh3 has been investigated. Dihydromyrcenol is a widely used fragrance ingredient and has been evaluated for developmental toxicity in pregnant Sprague-Dawley rats.
Solubility in organics
Practically insoluble in water, soluble in alcohol and oils.
