The problem about microplastics is discussed more and more in media and in academia. In cosmetic products microplastic is used, e.g., as abrasive particles in face peelings. Sewage carries the microplastic into the environment. Here it leads to various problems. Pollutants can accumulate, and it is also mistaken with food by animals. This paper studies whether biowaxes have the physical and technical characteristics to be used as an environmentally friendly alternative instead.
