Abstract:
1. A phosphate-containing machine dishwasher detergent, comprising (A) 0.01-20% by weight of at least one alcohol alkoxylate of general formula (I) where R R R x, y: each independently mean value in the range of 0.5-80, where the individual alkylene oxide unit is optionally present as a block or in random distribution, (B) 0.01-10% by weight of at least one alcohol ethoxylate of general formula (II) where R z: mean value of 2-10, where a content of residual alcohol R (C) 0-15% by weight of at least one sulfonate-containing polymer, (D) 0.5-12% by weight of at least one hydrophilically modified polycarboxylate which comprises alkylene oxide units and are obtained from (1) 50 to 93 mol % of acrylic acid and/or of a water-soluble salt of acrylic acid, (2) 5 to 30 mol % of methacrylic acid and/or of a water-soluble salt of methacrylic acid and (3) 2 to 20 mol % of at least one nonionic monomer of the formula VI wherein: R R R R s is 3 to 50, where components (1), (2) and (3) are incorporated by random or block copolymerization, (E) 0-8% by weight of at least one polycarboxylate, (F) 1-70% by weight of at least one phosphate and (G) 0.01-60% by weight of at least one further additive, where the sum of components (A), (B), (C), (D), (E), (F) and (G) is 100% by weight.
