Abstract
The present invention provides novel nanoscale cellulose particles and also a process for their production. The cellulose-based particles obtained have volume-averaged particle sizes of less than 300 run. These nanoparticles are produced from slightly oxidized cellulose and by input of energy into a water-containing medium after or during dispersion.
