practical analysis

As a practical analysis, we examined the wear of the synthetic hair and the razor blades. For this intensive test, we attached a shaving brush head to a drill and 3D printer, which was to be worn on a piece of leather. The resulting liquid and shaving foam were then examined in the BioLab for microplastic particles. In this method, we were unable to detect microplastics, but we were able to detect severe wear on the tips of the hair.
