Cellulose nanocrystals (CNC) and cellulose nanofibers (CNF) are refined from wood. Their renewable nature and their unique properties make them interesting materials for a wide range of applications.
The high tensile strength and good biocompatibility make it suitable for many applications ranging from paper, food and sanitary products to all kinds of reinforcement and filler materials.
Although nanocellulose is touted as a “bionanomaterial,” CNC in a dry frozen state is particularly respirable, which makes it a potential health hazard. Although some older studies have seemed to disprove the harmful effects of nanocellulose, some newer research has shown potentially adverse effects.
