Another sophisticated technique, CO2 extraction, uses supercritical carbon dioxide as a solvent. Finally, the precise parameters of the extraction process, such as temperature, pressure, and duration, are carefully calibrated by the producer to optimize the yield and preserve the most delicate top notes.
Solvent Extraction and Absolute Oils For delicate flowers, such as jasmine, rose, or chamomile, which would be damaged by the high temperatures of steam distillation, solvent extraction is the preferred method. Factors Influencing Oil Quality The quality and chemical composition of an essential oil are not static; they are influenced by a constellation of environmental and procedural factors.
