What Is Geraniol Fine 98%?
Geraniol Fine 98% is a highly purified form of geraniol, a naturally occurring fragrant alcohol that gives many flowers their characteristic rosy aroma. The material sold under this name is produced by Symrise, one of the major aroma houses, though several other suppliers also offer comparable grades of geraniol.
Most commercial geraniol comes from renewable botanical sources such as citronella or palmarosa oil. The crude essential oil is distilled, then the geraniol fraction is isolated and carefully rectified to remove color bodies and off notes until a minimum purity of 98 percent is reached. No stabilizers are needed because the molecule is intrinsically stable when kept away from strong light and air.
At room temperature the ingredient appears as a perfectly clear colorless liquid that moves with the viscosity of light syrup. The absence of tint is a quick visual cue that the batch is fresh and well refined.
Perfumers reach for geraniol in everything from fine fragrance to soap bases, making it one of the workhorse floral materials on any compounding bench. Because the feedstock is plentiful and the process well established the price sits in the moderate range, affordable for large scale toiletries yet harmonious enough for luxury perfumes.
When stored in a cool dark place and kept tightly closed geraniol typically stays in spec for two to three years before the first signs of oxidation appear. Simple rotation of inventory usually prevents any issues.
Geraniol Fine 98%’s Scent Description
This ingredient lives squarely in the floral family, and more specifically in the rose–geranium corner of that group.
Off a blotter it opens with the crisp brightness of freshly cut rose petals mingled with a hint of sweet litchi pulp. Within a minute a leafy geranium nuance steps forward adding a soft green edge that keeps the sweetness from feeling sugary. Underneath, a gentle herbal warmth lingers, reminiscent of lemon verbena and a whisper of citrus zest.
Perfumers talk about top, middle and base notes to describe the life of a fragrance on skin. Geraniol sits mainly in the heart, the part that blooms after the initial sparkle fades but before the deeper fixatives take over. It contributes a clear floral signature for several hours, then slowly trails off without leaving a heavy aftertaste.
Projection is moderate: it radiates enough for the wearer to enjoy a delicate aura yet rarely dominates a blend. Longevity on a blotter reaches four to six hours, longer in compositions where it is supported by woods, musks or resins.
How & Where To Use Geraniol Fine 98%
Geraniol Fine 98% is first choice whenever a clean natural rose nuance is needed without the weight or spice of whole rose oil. A perfumer uses it to build classic rose accords, brighten fruity florals or lend a tender petal glow to modern woody compositions. It slips easily into heart notes where its gentle sweetness smooths sharp edges and pulls disparate materials together.
At trace levels, around 0.05%, it adds a subtle rosy lift that can freshen citrus or green openings without being recognisably floral. Between 0.3% and 1% the note becomes clearly rose-geranium, ideal for body sprays, bar soaps and fabric softeners that call for a friendly everyday floral. In fine fragrance the common range is 1% to 4% of the concentrate, enough to give a blooming centre yet still leave room for more characterful naturals like rose absolute or geranium oil.
Above 5% geraniol starts to dominate with a syrupy sweetness that can flatten a blend and feel old fashioned. Over-use may also bump up the allergen count flagged on EU labels, so most perfumers cap at 8% even in cost-sensitive detergents. If a formulation already contains citronellol or phenethyl alcohol the combined powdery effect can feel heavy; in that case a lighter touch or substitution with dimethyl benzyl carbinol or a modern captive rose molecule might be wiser.
In aquatic or high-tech masculine briefs geraniol can still play a role when paired with icy aromatics like dihydromyrcenol, adding a soft human warmth that keeps the composition from smelling too synthetic. It rarely fits in dark oriental bases where its fresh transparency clashes with resins and animalics.
No special prep work is needed beyond gentle warming if the drum has been stored in a cool warehouse and the liquid thickens. Pre-weigh into an amber glass beaker, cover promptly and wipe the rim of the stock bottle to minimise air contact. Because the ingredient is colourless it will not tint finished products, making it suitable for white soaps and clear gels.
Safely Information
Working with any fragrance ingredient calls for a few basic precautions.
- Always dilute before smelling: create a 10% or weaker solution in perfumer’s alcohol or dip a blotter briefly then wave it to avoid a concentrated hit
- Do not sniff straight from the bottle: direct inhalation can overwhelm the senses and irritate nasal passages
- Ensure good ventilation: blend at a fume hood or open bench with adequate airflow to keep vapour levels low
- Wear gloves and safety glasses: the material is an alcohol that can defat skin and may sting if splashed in the eyes
- Mind potential sensitisation: geraniol is listed as an allergen in EU cosmetics so prolonged skin contact may trigger irritation in susceptible individuals
- Health considerations: consult a medical professional before handling aroma chemicals if pregnant or breastfeeding and avoid extended exposure to high concentrations
Always refer to the latest supplier MSDS for full hazard data and update your files whenever a new revision is issued. Check current IFRA guidelines for category-specific maximum levels and formulate within those limits to ensure consumer safety.
How To Store & Dispose of Geraniol Fine 98%
Good storage habits keep this rosy alcohol fresh and vibrant. A cool dark cupboard is generally sufficient but refrigeration can stretch the shelf life beyond two years by slowing oxidation. Wherever you store it keep the bottle away from direct sunlight heaters and any source of ignition since the flash point sits just over 100 °C.
Air contact is the main enemy. Choose bottles that let you top up headspace with the liquid itself or an inert gas so the surface area exposed to oxygen stays minimal. Polycone caps form a tight seal that resists evaporation and leakage far better than glass droppers which often wick scent into the threads and let air creep back in.
When you make dilutions transfer only what you need then close the stock container immediately. Wipe rims dry before tightening the cap to prevent residues from forming a sticky crust. Always label every bottle clearly with the ingredient name lot number and hazard pictograms so anyone in the workspace can identify contents at a glance.
Disposal is straightforward because geraniol is readily biodegradable. Small lab-scale residues can usually be washed down the drain with plenty of running water if local regulations permit. For larger volumes collect the liquid in a sealed drum and hand it over to a licensed chemical waste contractor who will direct it to an aerobic treatment facility or energy-recovery incinerator. Rinse empty bottles with warm soapy water let them dry then recycle or discard according to municipal guidelines.
Summary
Geraniol Fine 98% is a high purity floral alcohol that smells like fresh rose petals touched with green geranium hints. Its clean natural character makes it a staple for building rose accords brightening fruity bouquets and softening sharp edges in everything from fine fragrance to household cleaners.
The material is affordable renewable and easy to integrate yet still refined enough for luxury work. Stability is good provided you guard it from light and excess air and its clear colour means it will not stain pale bases. Use levels typically fall between 0.1 percent and 8 percent with care taken not to overload blends or trigger allergen limits.
Symrise supplies commercial quantities in bulk but small bottles can be sourced from fragrance labs specialty hobby shops and various online resellers that carry generic geraniol of comparable purity. Whether you are compounding a prestige perfume or trialing a new soap scent this versatile rose note deserves a spot on the bench.
