Abstract (en)

[origin: DE19819187A1] The invention relates to machine dishwashing detergents which contain phosphates. The inventive detergents not only preserve glass and decorative features but have an excellent cleaning capacity, even on problem stains such as tea, egg, milk and oat flakes. According to the invention, the detergents contain a further builder in addition to the phosphates, in the form of a powdery to granular additive. Said additive contains the following essential constituents: a crystalline lamellar silicate of the general formula (I) NaMSixO2x+1.yH2O wherein M represents sodium or hydrogen, x is a number from 1.9 to 22 and y represents a number from 0 to 33; and (co)polymeric polycarboxylic acids. Additives of this type can be processed easily in terms of the production technology required.
