What Is Jasmone Cis?
Jasmone Cis is a single aroma molecule identified in the mid-1960s during research into the characteristic notes of jasmine absolute. Today it is produced at industrial scale through controlled chemical synthesis that starts from readily available terpenoid feedstocks, then finishes with an isomerisation step that locks the structure into its cis form. Though it occurs naturally in jasmine blossoms, commercial material is classed as nature-identical rather than directly extracted, allowing for reliable quality and a steadier supply.
At room temperature you will find it as a clear, mobile liquid that flows easily when poured. The material has a moderate molecular weight and a relatively low vapour pressure, factors that influence how it behaves in finished fragrances. Despite the multi-step process required to make it, Jasmone Cis remains a mid-priced ingredient thanks to high demand matched by efficient production.
Formulators reach for it whenever they need to build authentic floral accords, so it appears across fine fragrance, personal care and even home scent products. Its popularity also stems from its usefulness in reconstructing natural oils like jasmine and tuberose where regulatory or cost limits cap the level of true absolutes. All in all, it is a staple that most fragrance laboratories keep in regular stock.
What Does Jasmone Cis Smell Like?
Perfumers classify Jasmone Cis squarely in the floral family. Off a blotter it opens with a vivid jasmine character that feels both petal fresh and slightly green, as if a breeze has just passed through a sun-warmed garden. Within seconds a smooth warmth surfaces, giving the note a rounded, almost velvety quality rather than a sharp or indolic punch.
Technically it sits in the heart, or middle note, region. That means it shows itself clearly after the brighter top notes have evaporated and continues to guide the composition toward its drydown. Because its volatility is moderate it bridges nicely between fleeting citrus lifts and deeper musks or woods, making it a reliable backbone for floral blends.
Projection is noticeable yet not overpowering; it radiates a gentle halo that feels natural rather than shouty. On a standard blotter the aroma holds for roughly three days before fading to a subtle whisper, confirming its respectable longevity for a molecule of its size.
How & Where To Use Jasmone Cis
Put simply this is a friendly material to work with. It pours easily, behaves predictably and does not fog the lab with overpowering fumes while you weigh it. A few minutes on the bench and you know exactly where you stand with it.
Perfumers pull Jasmone Cis into a formula when they want to amplify or rebuild natural jasmine, tuberose or other creamy white petals without tipping the blend into indolic territory. It fills the floral heart, lending lift and a quietly green shimmer that keeps the bouquet feeling alive. Reach for it when a jasmine absolute is too expensive, too animalic or when regulations limit your dose of natural.
Usage levels run from traces up to around 3 percent of the concentrate, though most fine fragrance sits in the 0.2–0.8 percent band. In shampoos or fabric conditioners you can push a little higher because the wash off format buffers the strength. Go lightly in air care mists or skin scents designed for close wear since the material blooms as it warms on the skin.
Perception changes with concentration. At very low levels it simply polishes a floral accord, softening rough edges. Mid levels reveal the full jasmine character plus a touch of warm greenness. Overdosage can crowd the heart note and flatten the sparkle of top notes so balance it with fresh citrus or hedione to keep the blend airy.
Applications span fine fragrance, creams, lotions, haircare and bar or liquid soap where it shows solid stability across the usual pH range. It shines in candles thanks to its five star burning score, delivering a realistic floral throw without turning smoky. It is less convincing in strong bleach systems where its odour fades quickly.
No special prep is needed beyond the usual. The material dissolves readily in ethanol and standard F&F solvents so you can weigh it straight into your diluent, swirl and move on.
Safety Information
Working with aroma chemicals always calls for sensible precautions and Jasmone Cis is no exception.
- Always dilute before smelling: prepare a 10 percent solution or less in ethanol or dipropylene glycol and evaluate from a blotter
- Avoid sniffing from the bottle: concentrated vapours can overwhelm your nose and mask subtler nuances
- Ensure good ventilation: open windows or use a fume hood to prevent inhalation of elevated vapour levels during weighing and blending
- Wear protective gear: nitrile gloves and safety glasses keep accidental splashes off skin and out of eyes
- Health considerations: some individuals may experience irritation or sensitisation, limit exposure time and consult a doctor before use if pregnant or breastfeeding, prolonged or high level contact can be harmful
In short respect the material, handle it responsibly and always consult the latest supplier safety data sheet for definitive guidance while observing current IFRA standards for permitted dosage in your end product.
Storage And Disposal
Unopened drums or bottles of Jasmone Cis remain in spec for around two to three years. Once you break the seal aim to finish the contents within eighteen months to enjoy the freshest odour profile.
Room temperature storage works as long as the area stays cool and shaded. A fridge at 4-8 °C can squeeze out extra months of life but is not essential. Whatever you choose keep the bottle out of direct sunlight and away from heaters or hot pipes.
Oxidation is the main enemy. Use polycone caps on both neat material and any dilutions since they form a tight seal. Dropper tops let air creep in so skip them. Decant into smaller bottles as the level falls to keep headspace minimal.
Label every container clearly with the name, date of receipt, batch number and basic hazard phrases. Good records save time when audits or reformulation work roll around.
For disposal do not pour leftovers down the sink. Small volumes can be soaked into an inert absorbent like vermiculite then placed in a sealed bag for chemical waste collection. Larger quantities should go to a licensed disposal contractor. The molecule is readily biodegradable yet it can harm aquatic life at higher concentrations so responsible handling protects waterways.
Summary
Jasmone Cis is a jasmine-leaning floral molecule that brings a green warm glow to the heart of a fragrance. It mimics the charm of natural absolutes at a friendlier price and slips easily into fine fragrance, haircare and even candles.
Work with it in traces to polish an accord or push toward three percent when you want unmistakable white petals. Stability is solid across most pH ranges and its mid tier cost keeps budgeting simple.
Perfumers love it because it is fun, versatile and dependable. Just store it well, watch for oxidation and you will have a go-to ingredient that earns its place on the bench time after time.
