Supercritical CO2 Botanical Oil Extraction
Supercritical CO2 is becoming an important commercial and industrial solvent due to its role in chemical extraction with its low toxicity and environmental impact. Fractional Extraction uses the solvency power of CO2 at different pressures and temperatures to isolate desired oils, waxes and other herbal distillates from a variety of plant species.
