COMERG • Chamomile extraction
German Chamomile
Matricaria chamomilla L.
Turn chamomile flowers into a soothing, skin-loving extract with COMERG equipment. Our cold, room-temperature, low-pressure process captures the calming actives of the flower, the bisabolol and bisabolol oxides that gentle heat-free extraction keeps intact.

Bisabolol rich
The flower
The calming bloom
German chamomile is one of the gentlest, most trusted botanicals in skincare and wellness. Its small white-and-gold flowers are rich in bisabolol and bisabolol oxides, the soothing actives that have made chamomile a fixture of soothing creams, balms and teas for centuries.
The flowers are processed cold, so those delicate actives reach the finished extract intact. Nothing is added, and the natural balance of the flower is preserved.

The extract
What the process delivers
Run on COMERG equipment, chamomile flowers yield a standardised, soothing extract, batch after batch. Because the extraction is cold and solvent-light, with no high heat, the calming actives carry straight through to the finished oil. The figures below are typical of a standardised BCha-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 full calming character of chamomile.
1
Pressurised R134a flooding
Non-toxic liquefied R134a gas is introduced to the dried chamomile 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 bisabolol, bisabolol oxides and farnesene, while the heat-sensitive soothing actives stay structurally intact.
3
Recovery and pure extract
The R134a is fully recovered and recycled in a closed loop. What is left is a concentrated chamomile extract, at least 20% volatile oil, with under 0.1 g/kg residue.
Aromatic profile
The compound fingerprint
Principal constituents identified by GC-MS, each above 1%. The bisabolol oxides and farnesene lead the profile and carry the calming, faintly sweet character that defines chamomile.

Why the COMERG line
Built for delicate botanicals like chamomile
The soothing character above is not an accident of the flower alone, it is what the right equipment makes repeatable. Our line is engineered around the things that matter when you process a gentle, active-rich botanical.
Room temperatureR134a aerosol extraction works cold and at low pressure, so chamomile's delicate actives are never cooked off.
Keeps the soothing activesBisabolol and its oxides are what make chamomile soothing. Cold extraction protects them where prolonged heat can degrade them.
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 chamomile, above all the soothing actives that heat and time can break down.

Questions
Chamomile extraction, explained
A 100% natural chamomile flower extract, product code BCha-20.1. It reaches at least 20% volatile oil, rich in bisabolol oxide, farnesene and bisabolone oxide, 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 soothing actives are preserved and solvent residue stays below 0.1 g/kg.
Chamomile's value lies in delicate actives like bisabolol and its oxides, which can degrade under prolonged heat. Cold R134a extraction protects them, so the extract keeps its soothing character.
Roughly 1 kg of extract represents around 85 to 100 kg of dried flowers, which is why a concentrated extract is so practical to formulate with.
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.
It is produced with a food-grade solvent per Directive 97/60/EC. It is a raw material for formulation, not intended for direct consumption or undiluted topical use, and users are responsible for compliance with applicable legislation.
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.
