<p>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(1) from 30% to 100% by weight of a premix consisting essen tially of(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 (M2/nO)x ? Me2O3 ? (SiO2)y 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;(B) optionally bleaching components selected from the group consisting of inorganic peroxyhydrate compounds capable of supplying H2O2 in water, activators for percompounds, for percompounds and mixtures thereof; - A (C) non-ionic surface-active compounds finely distri buted on and throughout component (A) or the mixture of components (A) and (B); where the mixture of component (A) to component (C) is in the ratio of 10:1 to 1:3; and(2) from 0 to 70% by weight of a powdery component obtained by hot drying of an aqueous composition containing conventional heat-insensitive washing components; as well as a process for the production of said pourable washing compositions. - B</p> |
