CO2 vs Solvent Extraction Chemical Residue Concerns

Purity and **chemical residue levels** are critical when selecting an extraction method, especially in **food, pharmaceuticals, and cosmetics**. This article compares the **residual risks of supercritical CO2 extraction vs solvent extraction**.

1. Risk of Chemical Contamination

• Supercritical CO2 Extraction: Leaves **no chemical residues**, making it ideal for **clean-label products**.
• Solvent Extraction: May leave **trace solvent residues**, requiring additional purification.

2. Regulatory Standards and Compliance

• CO2 Extraction: Meets **organic, FDA, and EU safety regulations**.
• Solvent Extraction: Requires **strict solvent residue testing** to meet compliance.

3. Safety in Consumer Products

• CO2 Extraction: Ensures **pure extracts for food, nutraceuticals, and skincare**.
• Solvent Extraction: Solvent traces can affect **flavor, safety, and skin irritation potential**.

4. Case Study: CO2 Extraction in Organic Essential Oils

A premium essential oil company eliminated **solvent contamination risks** by switching to CO2 extraction, leading to **higher consumer trust and certification approvals**.

5. Conclusion

For **zero chemical residue risk**, **supercritical CO2 extraction** is the best choice. Companies like **SHANGHAI NORTH BROOKS** provide **CO2 SUPERCRITICAL EXTRACTION MACHINE** solutions for **high-purity processing**.
