Arctander describes the odour like this: “extremely powerful and very diffusive oily-green, herbaceous and, in proper dilution, sweet, pleasant leafy-vegetable odor of moderate to poor tenacity.” he goes on to say it “has been used for the past 30 years in minute traces in violet perfumes, narcisse bases, and in topnote compositions as a green-fresh, natural and very diffusive note. the material is also used in the revived cucumber’ odor for hand-lotions etc. interesting effects are achieved with this material in muguet, lily, cyclamen, ylang-ylang, etc.”
