The first embodiment of the teaching according to the invention described above makes use in particular of this increased absorbency or absorption capacity of the dry materials which have been obtained using superheated steam as the drying medium .In this case a material obtained by spray drying and/ or fluidized bed drying in superheated steam is used for mixtures of useful materials from the field of wetting agents ,detergents and/or cleaning products .This second charging step ,which will be discussed in more detail in the description of the process according to the invention for the production of the charged  carrier beads ,generally takes place under conditions under which the composition to be introduced is present in free-flowing form.Accordingly， usefull materials liquid at room temperature and/or at the working temperature and/or solutions, emulsions and/or dispersions of useful materials are particularly suitable for chargingm,more particularly water  ,may be subsequently removed .However ,the technical teaching according to the invention is by no means confined to this form of charging.The carrier beads may also be charged with melts of the components to the components,to be introduced as the coating composition .By adopting suitable measure known per se to the expert ,it is possible to ensure that the coating composition is absorbed to the required extent into the prorous interior of the carrier beads
