Abstract

Disclosed is the use of a separation agent including fibril cellulose for phase separation, as well as to a method for the separation of at least one liquid phase from at least one phase selected from a second liquid phase, solid phase and semi-solid phase, where the method includes the steps of incorporating a separation agent including fibril cellulose to a mixture where separation of the phases is desired, followed by formation of phases and removing the phases.
