CO2 exposed to specific conditions (204 atm and 40??C), behaved like a non-polar organic solvent and its selectivity was enhanced by the use of polar entrainers or co-solvents such as ethanol or methanol [15], While the solvation conditions to fractionate the active constituents can vary from 100% carbon dioxide (CO2) to 100% methanol (CH3OH), the optimum levels were found to be 70% carbon dioxide
