In a first embodiment ,therefore ,the present invention relates to useful materials and mixture thereof for use in wetting agents ,detergents and /or cleaning poroducts in the form of free-flowing granules which are obtained by charging basic granules-hereinafter referred to as "carrier beads"-with a preparation contaning useful materials of the type mentioned above-hereinafter referred to as the "cotating" 5cmposition ".The inventon is characterized in that the carrier beads are a materials obtained by spray-drying and /or fluidized-bed drying in superheated steam.

In the improtant enbodiments of the invention ,at least a substantial percentage of the coating composition is introduced into the porous inner of the carrier beads and fill at least 10% by volume and,preferably ,a least 50%by volume of the accessible space within the inner structure .It can be useful in this regard,particularly depending on the physical character of the coating composition ,if only limited quantities or no significant quantities of the coating composition are present on the outer surface of the granules.
