Abstract

Pourable washing agent compositions comprising essentially a premix powder component and optionally a second powder component obtained by hot drying of an aqueous composition containing conventional heat-insensitive components, consisting essentially of PA1 (1) from 30% to 100% by weight of a premix consisting essentially of PA2 (A) finely-dispersed, water-insoluble silicate compounds having a calcium-binding power of at least 50 mg CaO/gm of anhydrous active substance and having the formula, combined water not shown, of EQU (M.sub.2/n O).sub.x .multidot. Me.sub.2 O.sub.3 .multidot. (SiO.sub.2).sub.y PA2 where M is a cation of the valence n, exchangeable with calcium, x is a number of from 0.7 to 1.5, Me is a member selected from aluminum and boron and y is a number of from 0.8 to 6, which silicate compounds optionally are partly replaced by highly dispersed silica in amounts of not more than 4% by weight, based on the weight of the premix; PA2 (B) optionally bleaching components selected from the group consisting of inorganic peroxyhydrate compounds capable of supplying H.sub.2 O.sub.2 in water, activators for percompounds, stabilizers for percompounds and mixtures thereof; PA2 (C…
