Accordingly ,one particular embodiment of the use of carrier beads for the production of solid formulation of useful materials of the type in quedtion containing in particular surface-active solids is the use of particularly fine particle and , inparticular ,inorganic water-insoluble carrier consitiuents which are suitable for dispersion in aqueous solution .Using limited quantities of binders which may be surface-active in character, it is possible to obtain carrier beads which may be charged with other useful materials .More particularly,the fine-paricle insoluble base materials ar in turn useful materials for the field of application in question particular significance is attributed in this regard to corresponding minerals capable of iron exchange ,Zeo lities are important representatives in the fileld of detergents and cleaning products ,particular significance being attributed to detergent-qualitly zeolite NaA andalso to other fine-particle,crystalline and optionallu swellable layer silicates of natural and /or synthetic origin.Carrier beads based on materials such as these may optionally be charged with increase quantities of surface-active compounds ,although in this case ,too,the percentage content of nonionic and/or anionic surfactant compounds in the end products is comparativelly low ,for example up to at most 35%by weight ,based on the charged carrierbeads (see,for example ,the disclosyres of Ep-B1 0 149 267or EP-A1 0 021 267)
