Sweet, spearmint, herbal and immediately pleasant. Present in many essential oils and headspace results. There is significant odour difference between this material and d-Carvone (which smells of caraway and has a much higher detection threshold) was due to two chiral forms.
Arctander describes it as: “Warm-herbaceous, breadlike, penetrating and diffusive odor, somewhat spicy, in extreme dilution also floral, overall reminiscent of spearmint oil (rectified) … used in perfume compositions, particularly in floral bases, where it introduces enormous power and often lends pleasing natural notes to the fragrance. However, it demands great skill and experience in application. It seems to constitute a very good and compatible companion to Rose Oxide and the Jasmone chemicals.”
