CO2 Extraction vs Ethanol Extraction: Which Method is Best for High-Purity Botanical Extractions?

Introduction

CO2 and ethanol extraction are two of the most widely used methods for isolating cannabinoids, essential oils, nutraceuticals, and other bioactive compounds. This article compares yield, purity, and cost-effectiveness.

1. Overview of CO2 and Ethanol Extraction

• CO2 Supercritical Extraction – Uses high-pressure CO2 as a solvent to isolate compounds without chemical residues.

• Ethanol Extraction – Uses solvent-based soaking to dissolve bioactives, requiring post-processing for solvent removal.

2. Key Differences Between CO2 Extraction & Ethanol Extraction

3. Case Study: CO2 vs Ethanol Extraction for CBD

A CBD facility found CO2 extraction achieved 98.5% purity, while ethanol extraction required additional refining.

4. Conclusion

For high-purity, solvent-free extracts, CO2 supercritical extraction MACHINE offers the best long-term solution.
