Nanocellulose is mainly used in medical implants [1,2], and in wound care applications. So it comes into direct contact with the tissue. The roles of the lung, the skin, and the gastro-intestinal tract as the main entrance gates take a back seat. Bacterial nanocellulose films are not considered toxic.


In combination with silver chloride, antibacterial pads are made [3]. Microcrystalline cellulose, however is used as a food additive E460i and also in the pharmaceutical industry. It serves as dietary fibre for low-calorie foods, as a release agent or as a carrier. There are reservations against the use of microcrystalline cellulose in the food sector, e.g. for the production of sauces and low-calorie preparations, because the intestinal walls are permeable for microcrystalline cellulose.

In pharmacy, it is applied as a binder and carrier for the manufacture of pills [4].
