Dehydrated cellulose nanofiber: New method to keep thickening agents tiny in transport and big in application

Many commercial products such as food, cosmetics, and inks contain cellulose nanofiber (CNF) as a thickening agent. However, CNFs have some limitations that prevent their more widespread use. Now, researchers from Osaka University have demonstrated a method of dehydrating CNFs to a dense powder without affecting their three key properties.
