In one important  embodiment ,mot only does the coating composition introduce into the carrier beads contain useful materials of type mantioned, the carrier beads themselves also preferably consist at least partly and preferably at least predominantly of useful materials for wetting agents ,detergents and/or cleaning products and have been products as described above by drying a liquid and ,in particular ,water-containing preparation in superheated steam. Suitable surface-active materials may be used as an important useful material constituent in the actual production of the possible using even these compounds with their tendency to stick and gel ,so that they are normally difficult to dissolve or emulsify in water ,to produce highly porous and hence absorbent  carrier beads which are suitable for charging the inner structure of the carrier beads with other useful materials of the type mentioned above and which ,at the same time,are distinguished by optimized dissolvability or emulsifiability in the aqueous phase typically used in practice .                                                                                           

Accorfingly,the present invention also relates to porous carrier beads as such for the production of solid wetting agents ,detergents and/or cleaning products shouwing improved solubility in water which  are particularly suitable for use as carriers for absorbing useful materials and /or auxiliaries of the type mentioned above and which are botained by drying a liquid and ,in particular,water-tontaining preparation of the carrier bead material in a hot drying gas ,the propous carriers beads according to the invention being characterized in that they are produced by spray dying and /or fluidized bed drying in superheated team.
