Why choose CO2 extraction?
Why choose supercritical carbon dioxide extraction over solvent extraction?
Avoid solvent residue for your raw materials
Low-temperature extraction can better preserve the active ingredients for you
The green and environmentally friendly extraction method can extract active ingredients of higher purity
No chemical residue of any kind
No heavy metal residue of any kind
It has better stability in the formulas of cosmetics and nutritional health products.
The choice of carbon dioxide extraction is not based on cost considerations, but rather to ensure its reliability and long-term product performance.

Process Features of SCFE-CO2 Extraction
Solvent: liquid or sub-liquid carbon dioxide or mixture solvent ·
Dissolving: controllable, strong dissolving capability for organic matters
Extracting: strengthened extraction at high pressure, rapid and complete
Separating: easy Selectivity: controllable with temperature, pressure and co-solvent
Operating: half auto-controlling, convenient
Technical Advantages of SCFE-CO2
As a solvent, the colorless, odorless, tasteless, non-toxic and inert carbon dioxide leads to green
and healthy products and safe operating. ·As a gas at room temperature, carbon dioxide does not remain in the product and can be separated easily during production. ·Due to low extraction temperature, generally about 30℃, the products are very natural and Original.
Due to the strong penetrability and dissolving capability of SC-CO2, the extraction is very fast and complete companied by controllable selectivity. ·High-pressure carbon dioxide has sterilization and anti-oxidation effects. ·The extraction is conducted in a close dark system, which avoids the decomposing of product caused by light.

Frequently Asked Questions
Carbon dioxide extracts are made using supercritical carbon dioxide under controlled pressure and temperature, without the need for organic solvents. They extract active ingredients (non-volatile and heat-sensitive compounds) at low temperatures. Compared with other extraction methods, they have a higher purity.
From the raw material end, we need to ensure that the planting environment, picking time and quality inspection of the raw materials pass. In the extraction stage, it can be controlled through fixed extraction parameters, verified process conditions and internal standards for inspection and review. This can ensure the consistency of each batch.
