Abstract

A method for reduction of the viral infectiousness of potentially infectious material, such as human or animal body fluids or fractions derived therefrom from which biologically active substances can be isolated, wherein the infectiousness is due to non-lipid-coated viruses characterized in that PA1 said potentially infectious material for the isolation of said biologically active substances is treated with PA1 a hydrophobic phase which is essentially insoluble in water and is capable of forming a two-phase system with said potentially infectious material, and PA1 said hydrophobic phase is separated from the potentially infectious material thus treated.
