Why was cold ethanol used in plasma fractionation?

developed cold ethanol fractionation for isolating different blood plasma fractions on an industrial scale during the first half of the last century. The fractionation process uses different solubility of plasma proteins by varying the pH, ethanol concentration, temperature, ionic strength and protein concentration (Cohn et al., 1946). Initially, the main reason for developing plasma fractionation on a large scale was for purification of albumin. Albumin is used for treating shock, hypoproteinemia (Janeway et al., 1944), acute or chronic nephritis (Thorn & Armstrong, 1945) and hepatic cirrhosis (Thorn et al., 1946) as well as other disorders.
