摘要

A phosphate-free detergent formulation for machine dishwashing, having from 1 to 20% by weight of a mixture of from 5 to 95% by weight of hydrophobically modified polycarboxylates I formed from 20 to 80 mol % of at least one monoethylenically unsaturated C3-C10-mono- or -dicarboxylic acid or anhydrides thereof, from 0 to 80 mol % of at least one monomer of the general formula (I) in which R1, R2 and R3 are each independently H, CH3 or C2H5, and R4 is a linear, branched or cyclic radical having from 1 to 6 carbon atoms or an aromatic radical having from 6 to 12 carbon atoms, and from 0 to 20 mol % of at least one further monomer, from 5 to 95% by weight of hydrophilically modified polycarboxylates II, where the sum of a1) and a2) adds up to 100% by weight.
