An in-depth review of supercritical carbon dioxide extraction chemistry, temperature parameters, and solvent-free purity metrics for active botanicals.
By Dr. Marcus Thorne, Director of Extraction Technology
In the botanical manufacturing industry, extracting delicate active compounds from plant matter without thermal degradation or chemical contamination is a primary challenge. Traditional extraction methods rely on petrochemical solvents like hexane, methanol, or ethanol. While effective, these solvents can leave toxic residues and strip away volatile terpenes.
To achieve maximum purity, we utilize Supercritical Carbon Dioxide ($CO2$) Extraction as our primary method for lipophilic extracts and essential oils.
The Physical Chemistry of Supercritical $CO2$...

Analyzing how maintaining low mechanical friction temperatures protects volatile compounds, terpene fractions, and fatty acids.
By Jean-Pierre Laurent, Master Distiller
Carrier and essential oils are highly sensitive to thermal degradation. Standard industrial expeller pressing can generate friction temperatures exceeding 90°C (194°F). While this high heat increases oil yields, it alters the delicate molecular structures of essential fatty acids and volatile terpene compounds, stripping the oil of its therapeutic qualities.
The Chemistry of ColdPressed Oils
Coldpressing is a mechanical extraction method that squeezes oils out of seeds, nuts, or fruits without using external heat or chemical solvents. By keeping extraction temperatures low, we preserve the vital phytonutrients that make botanical oils therapeutically active:...
