ABSTRACT:
A method of removing lipid soluble chemicals from a biological material containing the lipid soluble chemicals comprising bringing the biological material containing the lipid soluble chemicals into contact with an effective amount of an organic alcohol whose solubility in an aqueous solution at the temperature of use is .ltoreq.0.6% and/or a halogenated hydrocarbon having more than one type of halogen, agitating the resultant mixture and achieving a phase separation of the biological material and the organic alcohol and/or halogenated hydrocarbon. The method is particularly useful for producing relatively virus free physiologically acceptable plasma.
