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, Eta 0, (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-a-vis conventional MFC as known in the art. 本发明涉及微原纤化纤维素("MFC")，特别涉及以下微原纤化纤维素，其在形态上不同于本领域已知的常规MFC和/或提供改善的保水性和/或改善的流变性质，特别是相对于本领域已知的常规MFC，在溶液中增加的零剪切粘度η(又称为："静止粘度"，即不存在剪切力的情况下的粘度)，特别是在作为溶剂的聚乙二醇(PEG)中。
