    Abstract: The invention provides a granulate comprising particles having sizes substantially within the range 0.15 to 1.25 mm, the granulate consisting of: (a) about 1 to 99 weight % of partially or completely hydrated sodium tripolyphosphate containing water of hydration in a proportion of at least about 10 weight %, based on the theoretically possible water content, the anhydrous sodium tripolyphosphate containing about 20 to 90 weight % of phase-I-material prior to its being hydrated, the balance being phase-II, and (b) about 99 to 1 weight % of a water-insoluble alumino silicate ion exchanger material of the general formula (Cat2/nO)x.Me2O3.(SiO2)y.zH2O in which Cat stands for a calcium exchangeable cation with the valency n, x is 0.7 to 1.5, Me stands for boron or aluminum, y is 0.8 to 6, and z is 1.8 to 13.5. The invention also includes a spray process for making a granulate as just specified. The present granulate can be made with a particle size distribution which gives it particular utility as a detergent composition constituent.

    Abstract: The invention relates to a composition suitable for use in cleaning panes of glass, consisting of a pelleted blend of surfactants, the composition containing: (a) a water-soluble alkali metal polyphosphate of high molecular weight with a P2O5-content of 60 to 70 weight %; (b) at least one alkali metal carbonate or hydrogen-carbonate; (c) at least one crystalline substance producing an acid reaction in aqueous solution; (d) at least one anion-active and/or non-ionic surfactant; and (e) at least one filler, if desired or convenient.
