Beschreibung
Zusammenfassung:	The present invention relates to microfibrillated cellulose ("MFC"), in particular to microfibrillated cellulose, which is morphologically different from conventional MFC known in the art and/or which provides improved water retention properties and/or improved rheological properties, in particular increased zero shear viscosity, η0, (also known as: "viscosity at rest", i.e. viscosity in the absence of shear forces), in solution, in particular in polyethylene glycol (PEG) as solvent, vis-à-vis conventional MFC as known in the art.
