COMERG • Lavender extraction
True Lavender
Lavandula angustifolia Mill.
Turn fresh lavender flowers into a soft, true-to-bloom fragrance extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the calming floral signature of lavender, the linalool and linalyl acetate that perfumers prize, without the heat that can blunt the delicate ester.

The flower
The calm of the Bulgarian fields
True lavender, Lavandula angustifolia, gives the sweet, soft, floral scent that the whole world reaches for to relax. Bulgaria is one of the largest lavender growers on earth, and its fields are known for a beautifully balanced oil, rich in linalool and its gentle ester linalyl acetate.
We work with the fresh inflorescence, picked in July at full flower and processed cold so the soft top notes survive intact. Nothing is added, and the natural balance that makes lavender so calming is carried straight into the extract.

The extract
What the process delivers
Run on COMERG equipment, fresh lavender yields a standardised, true-to-bloom extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the soft floral signature carries straight through to the finished oil. The figures below are typical of a standardised lavender 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 full softness of fresh lavender.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the fresh lavender flowers 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 linalool, the linalyl acetate and the soft floral compounds, while the heat-sensitive ester that gives lavender its calm stays intact.
3
Recovery and pure extract
The R134a is fully recovered and recycled in a closed loop. What is left is a concentrated lavender extract, at least 70% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. Linalool and linalyl acetate lead together, the alcohol-and-ester pair that gives true lavender its soft, calming character.

Natural fragrance
This lavender extract is intended for fragrance and cosmetic use rather than food. It can be taken concentrated or diluted in a carrier oil to suit the application, and like all our extracts it is a raw material for formulation, not for direct or undiluted use.
Why the COMERG line
Built for delicate florals like lavender
The softness above is fragile, and prolonged heat is what usually flattens it. Our line is engineered around the things that matter when you process a delicate, ester-rich flower.
Room temperatureR134a aerosol extraction works cold and at low pressure, so the soft floral top notes are never cooked off.
Protects the esterLinalyl acetate, the ester behind lavender's calm, can break down under steam heat. Cold extraction keeps it intact.
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 flower'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 keeps more of the lavender, with a soft, true-to-bloom result.

Questions
Lavender extraction, explained
A 100% natural lavender extract from Lavandula angustifolia. It reaches at least 70% volatile oil, led by around 33% linalool and 23% linalyl acetate, with no additives.
Liquefied food-grade gas extraction at room temperature, below 25 °C, and low pressure. Because there is no high heat, the delicate aromatic compounds are preserved and solvent residue stays below 0.1 g/kg.
Lavender's calm comes largely from linalyl acetate, an ester that can hydrolyse and fade under the heat of steam distillation. Cold R134a extraction keeps it intact for a softer, truer scent.
Roughly 1 kg of extract represents around 100 kg of fresh lavender flowers.
This lavender extract is intended for perfumery and cosmetics rather than food. It is a raw material for formulation, not 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.
