What is Supercritical CO₂ and Why Is It Ideal for Green Extraction?
Carbon dioxide usually behaves as a gas at standard temperature and pressure, it can exist in a liquid state or in a solid state called dry ice when cooled and pressurised sufficiently.
There is however another fluid phase that CO2 can exist in at or above its critical point of 31°C and 73.8 bar, called supercritical carbon dioxide (scCO2). In this phase, the fluid adopts unique properties where it can permeate like a gas through solids but is able to dissolve molecules like a liquid.
The true power of scCO2 as an extraction medium is that by changing the pressure and temperature we can adjust the overall density of the supercritical liquid, which allows to optimize extraction conditions and selectivity for certain molecules. It has become an important commercial and industrial solvent due to its low running costs, high availability and chemical stability, low environmental impact (non toxic and solvent-free medium) , reusability, and because it allows extraction of most known components with minimum damage or denaturing to preserve thermolabile compounds.
