Common name(s): Cis Jasmone

Chemical name: 3-methyl-2-[(Z)-pent-2-enyl]cyclopent-2-en-1-one

CAS #: 488-10-8

Supplier: Hermitage Oils UK

Note: Heart

Family: Floral

Diffusion: 5

Dilution: 10%

Blends well with: amyris, benzyl benzoate, bergamot, benzyl salicylate, cardamom abs., carrot seed, celery, cistus, clove bud, black currant bud abs., alpha and beta damascone, geraniol, geranyl acetate, jasmine abs., lavender abs., mimosa, nerol, nerolidol, neryl acetate, orris, petitgrain, raspberry ketone, tuberose, veramoss, ylang ylang, etc. (TGSC)

Interesting bits: Although it’s quite an expensive material compared to some of the other jasmine-like florals it has a large effect at low doses and is particularly helpful for improving diffusion and radiance in floral compositions that can be over-heavy, such as Tuberose. Occurs naturally in a range of flower scents as well as being present in bergamot, mint and other essential oils. (Hermitage Oils UK)

Very often hedione or cis-jasmone (which has an almost anise or liquorice smell by itself) is used to render the illusion of smelling a live jasmine vine. (Perfume Shrine)

Their nose: woody, herbal, floral, spicy, jasmine, celery, with a citrus nuance (TGSC)

Floral, green, jasmine, warm with distinct woody aspects as well a subtle minty quality…(Hermitage Oils UK)

Diffusive, warm-spicy, somewhat fruity, but in dilution more floral odor of good tenacity. Its beauty is truly demonstrated in dilutions below one percent, or in modest amounts in a perfume composition. The pure material has notes reminiscent of Celery seed, some find it “’bread-like”, others find it ““fruity”,“waxy” etc. Evaluation of a powerful odorant should be undertaken by proper dilution of the material so that nuances can be studied with- out the inconveniences of odor fatigue…Traces, often mere fractions of one percent, in a perfume oil may introduce just that wanted warmth and deep floral note almost unobtainable with other chemicals. (Steffen Arctander)

My nose: Cis Jasmone opens floral, with plumes of flower essences rising to greet me, petals, somewhat thin and refined. After 15min this note totally opens up like a blossom, fully floral now. Very sophisticated, delicate but with a hint of something “bad” yet beautiful at the same time (does that even make sense?). 30min on this is now fresh, airy, still floral and pristine. It is totally summery and carefree, also radiant and I can see how it could add lift to an overall composition. At 45min it’s morphed into something cool, crisp and floral, no longer warm. It’s still radiant and deeply satisfying. Cis jasmone is feminine but not in an overt way. Now after 1hr, the tail end of the top note, it remains crisp and exhilarating, candid with a touch of floral minimalism. 2hrs it’s sweeter, with a bit of a mint effect! Cleansing, luminous, and yes, the olfactive temperature remains cool. 3hrs into the dry down and it remains clean, crisp, clear and still floral beneath the surface. This is a tenacious note with a really nice hold. After 7hrs it begins to thin out and seems to have filled out or plumped up and gotten a bit fruitier. At the 12hr mark now there is a hint of cumin??? More than exiting it seems to be decaying. Then finally at 24hrs it finishes up in spice-land, that cumin thing is still there, though the whole effect is drying and less discernible.  

This was a really nice synthetic to take for a test drive but I’m really looking forward to using it in a composition — that’s where I think I’ll have some serious fun!

Have a wonderful Monday!
