Low Temperature Essential Oil Extraction

Steam distillation is used in many current essential oils extractions, but this technique exposes the product to temperatures over 100°C. These high temperatures cause many of the “top notes” to be destroyed or swept away, leaving a greatly reduced, less desirable yield. 

Supercritical CO₂ extraction of essential oils uses temperatures less than body temperature (37°C). Because of this low temperature, little thermal degradation of sensitive compounds occurs. The top notes are retained and the resulting yield is much greater.
