A bench-scale system that refines a finished botanical extract, selectively removing unwanted constituents at room temperature while preserving the aromatics and actives.
COMERG • Lavender extraction
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
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
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
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.
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.
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.
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
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.
Other extractables present. Per-batch GC-MS report available on request.

Why lavender, why cold
Lavandula angustifolia, Bulgaria
Versus steam distillation
Applications
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
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.
Why it wins
Against steam distillation, solvent and CO2, cold R134a extraction keeps more of the lavender, with a soft, true-to-bloom result.

From flower to extract
A complete COMERG line takes lavender from fresh flower to a finished extract. These are the core stages, each available as standalone equipment.
The heart of the line. Liquefied-gas systems that pull lavender oil cold, below 25 °C, from 10 l pilot units up to 2000 l.
Room temp • 97% recoveryCuts the lavender inflorescence cleanly in the field at full flower, so the freshest blooms reach the extractor fast.
Field stageFrom a 10 l pilot system to industrial 2000 l lines, the same cold process scales with your volume.
10 l - 2000 lQuestions
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.
