Description
Reported in several of the NAS food additive surveys, but no
technical effect (food functionality) given.
Chemical Properties
iso-CYCLOCITRAL is a colorless liquid. Insoluble in water, soluble in
alcohol and oils. Sp.Gr. 0.93. Powerful, and diffusive, foliage-green, "dark"-weedy and dry odor, sometimes described as "Flower-shop odor". The earthy
and wet-green notes are quite natural in high
dilution and resemble the odor of stems from
plants and flowers fresh from the soil.
Occurrence
Has apparently not been reported to occur in nature
Uses
iso-CYCLOCITRAL finds use in perfume compositions where
it blends excellently with Oakmoss products
(compensates for sweetness and lifts the topnote), with Ionones (freshness), Geranium and
Galbanum (enhances the green and “vegetable” notes), etc.
Preparation
By a Diels-Alder-type condensation of 2-methyl-l,3-pentadiene with crotonaldehyde(Bedoukian, 1967).
By a DieIs-Alder type condensation
of 2-Methyl-2,4-pentadiene and Crotonaldehyde. The reaction product is a mixture of
isomers commercially called iso-Cyclocitral
(after rectification).
