Also preferred are peeling bodies of silica and silicates or polylactides. Also possible, although not desired, is the use of synthetic peeling agents. Furthermore, the particles may be filled with active ingredients beads or microcapsules. Mixtures of said particles, as well as mixtures of said particles with drug-filled beads and microcapsules are also preferred.

If, when stored for one month at elevated temperature, the viscosity does not deviate too much from the originally measured viscosity, this is an indication that the preparation is stable over a prolonged period, for example one year.
