Rinse agent formulations for machine dishwashing, comprising as components: a) 1% to 20% by weight of copolymers of a1) 20% to 80% by weight of at least one monomer from the group consisting of monoethylenically unsaturated C<SUB>3</SUB>-C<SUB>10 </SUB>monocarboxylic or dicarboxylic acids or their anhydrides, a2) 10% to 80% by weight of at least one monomer of the general formula (I) in which R<SUP>1</SUP>, R<SUP>2 </SUP>and R<SUP>3 </SUP>independently of one another are H, CH<SUB>3 </SUB>or C<SUB>2</SUB>H<SUB>5</SUB>, R<SUP>4 </SUP>is a linear, branched or cyclic radical having 1 to 6 carbon atoms or an aromatic radical having 6 to 12 carbon atoms, and a3) 0% to 80% by weight of at least one further monomer, selected from the group consisting of olefins having 10 or more carbon atoms or mixtures thereof and reactive polyisobutenes having on average 12 to 100 carbon atoms, b) 1% to 30% by weight of low-foaming nonionic surfactants, c) 0% to 50% by weight of nonaqueous solvents, d) 0% to 15% by weight of solubilizers, e) 0% to 15% by weight of acidifiers, f) 0% to 10% by weight of one or more further additives such as anionic, cationic, zwitterionic and amphoteric surfactants, dyes, fragrances and corrosion inhibitors; g) water to 100% by weight.
