ABSTRACT:
The invention relates to builder compositions with improved dissolution residue behavior, obtained by bringinga) crystalline layered sodium silicate of the formula NaMSixO2x+1*yH2O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20, andb) water or an aqueous solution or dispersion of at least one detergent ingredient,c) where the molar ratio of component a) to the water from component b) is 0.5:1 to 20:1,into contact with one another and subsequently heat-treating the resulting builder composition at 30 to 400° C. for 0.5 to 1000 min.
