This inert ,fluid, is interesting because it reaches its ,supercritical, phase at a relatively low pressure (73.8 bara) and a low temperature (31.1 °C.). The relatively low temperature of the process and the stability of CO 2 also allows most compounds to be extracted with little damage or denaturing.

A ,supercritical fluid, (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist, but below the pressure required to compress it into a solid. It can effuse through porous solids like a gas, overcoming the mass transfer limitations that slow liquid transport through such materials.
