The Uses of TRANS-2-HEXEN-1-AL DIETHYL ACETAL
Suggested for use in perfume compositions, this acetal should not be considered as a variation of the aldehyde. It has its own odor and character, and since it is much milder, it is easier to apply to experimental perfumes. The greenness is not sharp and not typically leafy. It has a caramellic undertone resembling that found in Citral diethylacetal and other acetals. Once approved by the authorities for use in food flavors, this acetal could find use in various compositions, such as imitation GooseberrY, Apple, Wine, Grape, etc.
