Tobacco Leaf

Nicotiana tabacum L.

Turn cured tobacco leaf into a deep, smoky base-note extract for perfumery with COMERG equipment. Our cold, room-temperature, low-pressure process draws out the warm, leathery, hay-like character that anchors oriental and chypre fragrances, with no heat to scorch the leaf.

Deep base note

The leaf

A perfumer's base note

Tobacco, Nicotiana tabacum, is a fragrance material with a long history in fine perfumery. Its cured leaf gives a warm, dry, leathery and hay-like scent that perfumers use to anchor oriental, chypre and masculine accords, where it sits at the very base of the composition.

The dried leaf is cut and processed cold, so the finished extract keeps the rich, rounded depth of cured tobacco rather than a burnt or harsh note. Nothing is added, and the leaf's full base-note character is carried through.

The extract

What the process delivers

Run on COMERG equipment, cured tobacco leaf yields a deep, standardised base-note extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the warm, rounded character carries straight through. The figures below are typical of a standardised BTob-20.1 grade.

The method

Cold extraction, in three steps

No heat, no leftover solvent. This is what happens inside a COMERG aerosol system, and why the extract keeps the deep, rounded character of cured tobacco.

1

Pressurised R134a flooding

Non-toxic liquefied R134a gas is introduced to the cut tobacco leaf at controlled, low pressure. There is no heat, the cycle begins and stays at room temperature.

2

Selective dissolution

The liquid gas gently dissolves the leaf's aromatic and resinous compounds, the molecules that carry the warm, leathery base note, without scorching them.

3

Recovery and pure extract

The R134a is fully recovered and recycled in a closed loop. What is left is a concentrated tobacco extract, at least 20% volatile oil, with under 0.1 g/kg residue.

Composition profile

The compound fingerprint

Principal constituents identified by GC-MS, each above 1%. Nicotine is by far the major alkaloid, with phytol acetate next, while the warm, characteristic scent is carried by the minor constituents below it.

Applications

What you can make

Oriental & chypre accords Tobacco & leather notes Base-note fixative Masculine fragrance Niche perfumery

This extract is not edible and is highly poisonous because of its nicotine content. It is intended for use in perfumery and cosmetics only, taken concentrated or diluted in a carrier, with filling rates set to your application. Keep away from children.

Why the COMERG line

Built for deep, resinous materials

A rich, rounded tobacco base note depends on a process that does not burn the leaf. Our line is engineered around exactly the gentle, controlled extraction that resinous fragrance materials need.

Room temperatureR134a aerosol extraction works cold and at low pressure, so the leaf's warm character is never scorched into a burnt note.
Holds the base noteThe heavier resinous and aromatic molecules behind the leathery depth come through intact, for a rich, rounded base.
Fully automatedClosed-loop systems run the cycle for you, so results stay consistent and one operator can handle the line.
Fast cycles, high yieldLow-pressure extraction is quick and recovers up to 97% of the leaf's compounds, more than older high-pressure CO2 lines.
Scales with youFrom a 10 l pilot unit to 2000 l production, the same method grows from R&D batches to full output.
Clean and economicalIt uses around 85% less energy than solvent methods and needs no special hazardous-location facility.

Why it wins

Compared to the alternatives

Against steam distillation, solvent and CO2, cold R134a extraction gives a deep, clean tobacco base note with no residual hydrocarbon solvent.

Questions

Tobacco extraction, explained

A 100% natural tobacco leaf extract from Nicotiana tabacum, product code BTob-20.1. It reaches at least 20% volatile oil and carries the warm, leathery base note used in perfumery, with no additives.

Liquefied food-grade gas extraction at room temperature, below 25 °C, and low pressure. Because there is no high heat, the leaf's character is preserved without scorching and solvent residue stays below 0.1 g/kg.

No. It is not edible and is highly poisonous due to its nicotine content. It is a fragrance raw material for perfumery and cosmetics only, not for direct or undiluted use, and must be kept away from children.

Tobacco's value as a base note comes from heavier resinous molecules that harsh heat can burn or distort. Cold R134a extraction concentrates them gently, giving a rich, rounded depth rather than a burnt note.

Roughly 1 kg of extract represents around 350 to 450 kg of cured tobacco leaf.

Yes. The same cold process runs from a 10 l pilot unit to 2000 l production systems, so you can start small and grow without changing method.

Yes. A per-batch GC-MS analysis is available on request, and a Safety Data Sheet per 2006/1907/EC is supplied with the product.
