After two years of research work with the project partners, we have achieved very good results: a test toothpaste with the optimized beech wood cellulose particles is characterized by a low abrasion effect, but nevertheless good cleaning performance,” says Dr. Sandra Sarembe, project coordinator at Fraunhofer IMWS.

The biodegradable particles in toothpaste are used for the mechanical removal of bacterial plaque, tooth discoloration and food residues, but they may not damage tooth enamel. “In the material characterization of several cellulose types, we have consistently collected positive data. This also applies to the use of these substances in wash peelings and other skin cosmetics,” Sarembe continues.

The research team was able to scientifically confirm that cellulose particles have comparable effects in cosmetic products as a substitute for polyethylene. They are also biodegradable in water and can be produced at low cost. Cellulose particles can also be used as a filler in aluminum-free deodorants.
