COMERG • Lilac extraction
Lilac Blossom
Syringa vulgaris L.
Capture the scent of fresh lilac, one of the hardest flowers in all of perfumery to bottle, with COMERG equipment. Our cold, room-temperature, low-pressure process lifts the true lilac note, the lilac aldehydes and dimethoxybenzene, straight from the living bloom, with no heat to coarsen it.

Rare floral extract
The flower
The scent that resists bottling
Lilac, Syringa vulgaris, is one of spring's most loved scents and one of the most stubborn to capture. The flower yields almost no oil by distillation, which is why a true natural lilac is so rare. Its character comes from delicate lilac aldehydes and alcohols, lifted by sweet dimethoxybenzene and soft benzyl alcohol.
We work with fresh whole blossoms, picked in May and processed cold so those fragile molecules survive. The result is a rich, waxy floral extract that carries the real scent of the living bloom, not a reconstruction.

The extract
What the process delivers
Run on COMERG equipment, fresh lilac yields a rich, true-to-bloom floral extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the fragile lilac note carries straight through to the finished material. The figures below are typical of a standardised BLil-20.1 grade.

The method
Cold extraction, in three steps
No heat, no leftover solvent. This is what lets a flower that defeats distillation give up its scent inside a COMERG aerosol system.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the fresh lilac blossoms at controlled, low pressure. There is no heat, the cycle begins and stays at room temperature.
2
Selective aromatic dissolution
The liquid gas gently dissolves the lilac aldehydes, the lilac alcohols and the soft floral compounds, the delicate molecules that distillation simply destroys.
3
Recovery and pure extract
The R134a is fully recovered and recycled in a closed loop. What is left is a concentrated lilac extract, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. Sweet dimethoxybenzene leads, with benzyl alcohol and the signature lilac alcohols rounding out the true floral character. Values are typical and vary batch to batch.

This lilac extract is not for food. It is a rare fragrance and cosmetic raw material, taken concentrated or diluted in a carrier to suit the formula, and like all our extracts it is not for direct or undiluted use. Filling rates are set to your application.
Why the COMERG line
Built for the flowers others cannot capture
Lilac is the proof case. A flower that gives nothing to a still gives up its true scent to a cold, gentle process. Our line is engineered around exactly that kind of fragile, high-value bloom.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the fragile lilac molecules that heat destroys come through intact.
Captures the uncapturableWhere distillation yields almost nothing, cold gas extraction lifts a true, rich lilac that smells like the living flower.
Fully automatedClosed-loop systems run the cycle for you, so results stay consistent and one operator can handle the line.
Gentle, fast cyclesLow-pressure extraction is quick and recovers up to 97% of what the flower will give, with no thermal damage.
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
For a flower like lilac the contrast is stark, distillation barely works at all, while cold R134a extraction delivers a true, rich material.

Questions
Lilac extraction, explained
A 100% natural lilac flower extract from Syringa vulgaris, product code BLil-20.1. It carries the true lilac note, led by sweet dimethoxybenzene and the signature lilac alcohols, with no additives.
Lilac gives almost no oil by steam distillation, so there is effectively no lilac essential oil, and absolutes are notoriously hard. Cold gas extraction is one of the few ways to capture the real flower's scent.
Liquefied food-grade gas extraction at room temperature, below 25 °C, and low pressure. Because there is no high heat, the delicate floral compounds are preserved and solvent residue stays below 0.1 g/kg.
Roughly 1 kg of extract represents around 200 to 500 kg of fresh lilac flowers, which is part of why the material is so prized.
No. This lilac extract is not for food. It is a fragrance and cosmetic raw material, not intended for direct consumption or undiluted topical use.
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.
