A phosphate-free and phosphonate-free dishwashing detergent formulation, comprising (a) 1 - 15% by weight of the total composition of (a1) at least one of polyaspartic acid or modified polyaspartic acid or salts thereof, wherein the modified polyaspartic acid is obtainable by polycondensation of (i) 50 to 99 mol% of aspartic acid and (ii) 1 to 50 mol% of at least one carboxyl-containing compound different from aspartic acid and subsequent hydrolysis of the co-condensates with the addition of a base, (a2) at least one graft copolymer composed of (a21) at least one graft base selected from, oligosaccharides and polysaccharides, and side chains obtainable by grafting on of (a22) at least one ethylenically unsaturated mono- or dicarboxylic acid and (a23) at least one ethylenically unsaturated N-containing monomer with a permanent cationic charge, wherein the weight ratio of (a1) : (a2) is from 12 : 1 to 3 : 1; (b) 1 - 50% by weight of methylglycinediacetic acid (MGDA), glutamic acid diacetic acid (GLDA) or salts thereof as complexing agent; (c) 3 - 65 % by weight of builders and/or cobuilders; (d) 0.5 - 10 % by weight of nonionic surfactants; (e) 0 - 30% by weight of bleaches and bleach activators; (f) 0.1 - 8 % by weight of enzymes and enzyme stabilizers; and (g) 0 - 50% by weight of additives. (a) 1 - 15% by weight of the total composition of (a1) at least one of polyaspartic acid or modified polyaspartic acid or salts thereof, wherein the modified polyaspartic acid is obtainable by polycondensation of (i) 50 to 99 mol% of aspartic acid and (ii) 1 to 50 mol% of at least one carboxyl-containing compound different from aspartic acid and subsequent hydrolysis of the co-condensates with the addition of a base, (a2) at least one graft copolymer composed of (a21) at least one graft base selected from, oligosaccharides and polysaccharides, and side chains obtainable by grafting on of (a22) at least one ethylenically unsaturated mono- or dicarboxylic acid and (a23) at least one ethylenically unsaturated N-containing monomer with a permanent cationic charge, wherein the weight ratio of (a1) : (a2) is from 12 : 1 to 3 : 1; (a1) at least one of polyaspartic acid or modified polyaspartic acid or salts thereof, wherein the modified polyaspartic acid is obtainable by polycondensation of (i) 50 to 99 mol% of aspartic acid and (ii) 1 to 50 mol% of at least one carboxyl-containing compound different from aspartic acid and subsequent hydrolysis of the co-condensates with the addition of a base, (a2) at least one graft copolymer composed of (a21) at least one graft base selected from, oligosaccharides and polysaccharides, and side chains obtainable by grafting on of (a22) at least one ethylenically unsaturated mono- or dicarboxylic acid and (a23) at least one ethylenically unsaturated N-containing monomer with a permanent cationic charge, (a21) at least one graft base selected from, oligosaccharides and polysaccharides, and side chains obtainable by grafting on of (a22) at least one ethylenically unsaturated mono- or dicarboxylic acid and (a23) at least one ethylenically unsaturated N-containing monomer with a permanent cationic charge, (b) 1 - 50% by weight of methylglycinediacetic acid (MGDA), glutamic acid diacetic acid (GLDA) or salts thereof as complexing agent; (c) 3 - 65 % by weight of builders and/or cobuilders; (d) 0.5 - 10 % by weight of nonionic surfactants; (e) 0 - 30% by weight of bleaches and bleach activators; (f) 0.1 - 8 % by weight of enzymes and enzyme stabilizers; and (g) 0 - 50% by weight of additives. <EOS>
