Accordingly, room temperature denotes 22 0 C +/- 1O 0 C, preferably +/- 5 ° C.
  • Another important process step proves that the root resin melt with the active ingredient dissolved therein is immediately covered with a sufficiently thick layer of water of about the same temperature. As a result of this measure, a transparent gel immediately forms under the water. Without such overlap with equally warm water, the melt hardens and is not or hardly to be applied in this form.
  • the melt should therefore be showered or covered in a liquid state with about the same amount of warm water. With cold water, the gelation also works, but then, above all, a dispersion of the active ingredient will arise. After the water is added at the same temperature and forms an overlap of the melt - the water floats over the melt, the gel formation occurs and the gel grows rapidly in the mass against the surface of the water, where it absorbs water. This externally observable gel formation is assisted by the rapid connection of water and melt, for example by controlled stirring.
