    Abstract: Dishwashing compositions based on mixtures of (a) at least 5% by weight of at least one ammonium or alkali metal carbonate or of one ammonium or alkali metal sulphate, (b) at least 2% by weight of sodium silicate and (c) 0.5 to 20% by weight of water-soluble polymers which have a K value of 7 to 20 and are obtainable by polymerisation of maleic anhydride and, where appropriate, other ethylenically unsaturated compounds in an aromatic hydrocarbon at temperatures from 60 to 200@C in the presence of peroxy esters and by hydrolysis of the polymers.

    Abstract: Dishwashing compositions based on mixtures of (a) at least 5% by weight of at least one ammonium or alkali metal carbonate or of one ammonium or alkali metal sulphate, (b) at least 35% by weight of sodium silicate and (c) 0.5 to 20% by weight of water-soluble copolymers which have a molecular weight of 500 to 8000 and which contain, as copolymerised units, (1) 50 to 95% by weight of acrylic acid and/or methacrylic acid, (2) 0 to 25% by weight of acrylamide and/or methacrylamide and (3) 5 to 25% by weight of 2-acrylamido-2-methylpropanesulphonic acid, vinylsulphonic acid, styrenesulphonic acid, 3-sulphopropyl acrylate, 3-sulphopropyl methacrylate, mixtures thereof and/or alkali metal or ammonium salts thereof, with the proviso that the total of the amounts in % by weight under (1) to (3) is always 100.

    Abstract: PHOSPHATE AND SILICATE-FREE LOW-FOAMING DISHWASHING DETERGENTS AND AQUEOUS CONCENTRATES THEREFROM The subject invention relates to dishwashing detergents containing a partially neutralized aminocarboxylic acid, a water-soluble carboxyl group containing polymer, and a low-foaming nonionic surfactant. The pH of the detergent is between 6.0 and 8.5 and is controlled by appropriately selecting the amounts of ingredients to be used. The dishwashing detergents are particularly useful in automatic dishwashers, and offer several advantages because they are phosphate free, and are of neutral pH in aqueous solution.
