The most important elements in pratactice for the formation of the carrier beads are, on the one hand the production and use  of so- called tower powders which consist predominantly of water-soluble and /or water-insolubel.,inorganic and/organic constitutents and additives,for example of a laundry detergent. liquid components, such as nonionic surfactants,perfume oils and the like ,may then be introducedinto these tower powders ,Another constituent of the tower powders are generally wshing-active anionic surfactants, more particularly corresponding salts  which are solid at room temperature.However,surface active compnents such as these have hitherto been  used in only limited quantities as part of the solid starting component .The reason for this is the pronounced tendency of the surface- active compounds-solid at room temperature -to gel in the usual drying process underthe effect  of hot gases and the water vapor to be removes from the starting material.The resulting gelled surfactant particles or layers are generally  difficult to dissolve in water .Limiting the percentage of solid sufactant compounds usde in the production of tower powders is determined inter alia by the need to ensure adeuate spreading and permeation of the dried surface-active solids with inorganic and/ or organic and/or organic mixture constitunents  showing improved solubility or dispersibility in water.
