What Is Jasmacyclene?
Jasmacyclene is an aroma chemical developed by the Swiss fragrance house Givaudan, though a few other suppliers offer generic versions made to a similar purity. Chemically, it belongs to the cyclene family and is formed as an acetate ester during synthesis. Perfumery labs usually start with a cyclene backbone, introduce an acetyl group, then carry out careful distillation to obtain the finished material.
At room temperature it appears as a clear colourless liquid with a light consistency that pours easily from the drum. The ingredient is classified within the floral palette yet brings a distinctive fruity-green nuance that sets it apart from many straight Jasmine notes.
Formulators turn to Jasmacyclene when they want extra lift and natural sweetness in floral accords without relying on heavier traditional jasmines. It is fairly common in fine fragrance, functional products like shampoos and soaps and even in some home scent formats. While usage is widespread it is not a mass-volume commodity, so it sits in the mid to premium price bracket rather than the bargain category.
When stored in a tightly closed container away from heat and strong light, the material will normally remain in good condition for around two to three years before oxidation dulls its brightness. After that point it can still be used in low-level applications but the creative impact gradually weakens.
Jasmacyclene’s Scent Description
This ingredient falls squarely into the floral family, yet its personality is far from a simple bouquet. On a blotter the opening impression is a dewy Jasmine petal backed by crunchy green stems. Within seconds a juicy pear-like fruitiness surfaces, followed by a subtle hint of sweet anise that lends an almost licorice twist. As the scent settles, a light woody thread peeks through, adding gentle depth without turning the profile heavy.
Perfumers describe top, middle and base notes as the way a fragrance evolves over time. Top notes are the first burst, middle notes expand into the main theme and base notes are what linger longest. Jasmacyclene sits mainly in the upper heart, bridging the sparkle of the top and the body of the middle. It lends immediate radiance then carries through for several hours before gracefully stepping back.
Projection is moderate to strong, so a small percentage can broadcast well, especially in bright floral compositions. On paper it remains detectable for several days, a testament to its surprising staying power despite the airy character. In finished perfume the note helps extend the life of delicate florals without weighing them down, making it a quiet workhorse behind many modern blends.
How & Where To Use Jasmacyclene
Perfumers reach for Jasmacyclene when a floral accord feels flat and needs a juicy green lift without adding weight. A trace can brighten a jasmine absolute or help a muguet chord sparkle. At higher levels it can even stand in for part of the jasmine note itself, saving cost while keeping a natural feeling.
Fruity creations also benefit. Around 0.5 % it rounds out pear and apple bases, giving a crisp garden freshness. In tropical blends it partners well with lactonic peach or pineapple materials, adding depth that carries into the heart of the fragrance.
The ingredient shows its best side in soaps, shampoos and fabric conditioners thanks to top-tier bloom and damp substantivity. It hangs on fabric after a wash yet rinses clean, so it is popular in modern detergent bases that target long lasting but gentle scent.
Tenacity on dry skin is modest, so for fine fragrance it works as a supporting act rather than a soloist. Pair it with longer lived molecules like Hexyl Cinnamic Aldehyde or woody musks to stretch the floral effect through to the drydown.
The recommended working range is traces to 5 %, though the manufacturer allows up to 10 % in certain functional products. Below 0.2 % you mainly feel the green top sparkle. Between 0.5 % and 2 % the fruity jasmine heart dominates. Past 4 % the sweet anise facet can turn medicinal and overpower delicate notes, so moderation is wise.
Because it is an acetate ester Jasmacyclene should be pre-diluted to 10 % in ethanol, TEC or dipropylene glycol before evaluation. The dilution helps reveal its nuance and avoids nose fatigue. No special stabilisers are needed but keeping the stock bottle tightly closed slows hydrolysis and maintains freshness.
It does not behave well in very high pH bleach products where the ester bond can break, leading to off odour. In highly oriental or amber bases the crisp green profile may feel out of place, yet even there a drop can add welcome lift if handled with care.
Safely Using Jasmacyclene
Handle Jasmacyclene with the same respect you give any concentrated aroma chemical. Always start by making a dilution before smelling it. Never put your nose over the neat bottle, instead waft the diluted strip toward you in a ventilated space.
Work on a bench with good airflow or under a small fume hood to keep vapor build-up low. Wear nitrile gloves to keep the liquid off your skin and choose safety glasses that fit snugly. These simple steps limit the most common accidents in a perfume studio.
While brief exposure to low levels is generally safe, prolonged or high-level contact can irritate skin eyes and the respiratory tract. Some people may be allergic to esters or develop sensitisation over time. Discontinue use if redness itching or headaches occur and seek medical advice.
If you are pregnant or breastfeeding consult a healthcare professional before working with any aroma chemical including this one. There are no known reproductive hazards at trace levels but caution is sensible.
Keep Jasmacyclene away from food and never use fragrance utensils for edible products. In the event of a spill absorb with an inert material, seal it in a container then follow local chemical waste regulations. Do not pour leftovers down the drain where they can harm aquatic life.
Finally review the supplier Material Safety Data Sheet for the most up to date information. Guidelines such as IFRA standards can change as new research emerges so check them each time you formulate and adjust your use level if limits are updated.
How To Store & Dispose of Jasmacyclene
Store Jasmacyclene in airtight glass bottles kept in a cool dark cupboard away from heat sources and direct sunlight. Refrigeration is not mandatory but the lower stable temperature can slow oxidation and extend shelf life.
Choose bottles with polycone caps that create a tight seal. Avoid dropper tops because they allow air to creep in and accelerate hydrolysis. After pouring a working quantity top up the main bottle or decant into a smaller container so headspace stays minimal.
Label every container with the name Jasmacyclene, dilution strength, fill date and key hazard information so anyone in the workspace knows exactly what is inside.
For day-to-day work prepare a 10% dilution in ethanol, TEC or dipropylene glycol and keep that stock separate from the neat material. Wipe bottle threads after use to stop residue forming that could compromise the seal.
When the ingredient is no longer needed do not pour it down the drain. Jasmacyclene is non-biodegradable and harmful to aquatic life so untreated disposal can damage waterways. Small amounts can be absorbed onto sand or vermiculite then sealed in a labelled bag for hazardous waste collection. Larger volumes should go to a licensed chemical disposal facility able to incinerate or treat the waste according to local regulations.
Empty bottles should be rinsed with solvent, the rinse solution added to your waste container then the clean glass recycled where permitted.
Summary
Jasmacyclene is a Givaudan floral ingredient that smells of bright fruity jasmine with leafy green and sweet anise nuances. It lifts white-floral accords, freshens fruit notes and excels in soaps, shampoos and fabric conditioners thanks to strong wet-stage bloom.
The molecule occupies a mid price bracket yet delivers noticeable impact at low doses making it attractive for both niche creators and large-scale formulators. It remains stable in most systems except very alkaline bleach and, as a middle note, benefits from support by long-lived woods or musks when skin persistence is required.
Commercial quantities are available directly from Givaudan or authorised distributors while hobbyists can buy smaller packs from specialist perfume suppliers or reputable resellers carrying generic equivalents.
Handle with basic lab precautions, store it tightly sealed in a cool place and dispose of leftovers responsibly to enjoy the clean modern floral twist Jasmacyclene brings to countless fragrance styles.
