The present invention relates to a method for producing granular or pulverulent detergent compositions, comprising the production of a detergent base powder by drying an aqueous detergent slurry, which comprises adding to the slurry a copolymer which is obtained by free-radical copolymerization of (A) from 20 to 80% by weight of at least one monomer selected from the group consisting of monoethylenically unsaturated monocarboxylic acids, dicarboxylic acids and dicarboxylic anhydrides, and (B) from 20 to 80% by weight of at least one monomer selected from the group consisting of aliphatic or aromatic monoolefins.

Method for producing granular or powdery detergent compositions

A mixed powder or mixed granule for use in detergent formulations for machine dishwashing contains the following components: a) from 10 to 95% by weight of a copolymer of a1) from 50 to 93 mol % of acrylic acid and/or of a water-soluble salt of acrylic acid, a2) from 5 to 30 mol % of methacrylic acid and/or of a water-soluble salt of methacrylic acid, and a3) from 2 to 20 mol % of at least one nonionic monomer, wherein monomers a1) to a3) are copolymerized in a random or block manner, b) from 5 to 80% by weight of a complexing agent selected from the group consisting of a glycine-N,N-diacetic acid derivative and glutamic acid N,N-diacetic acid and salts thereof, c) from 0 to 20% by weight of a polyethylene glycol, of a nonionic surfactant or of a mixture thereof.

Detergent formulations for machine dishwashing comprising hydrophilically modified polycarboxylates

The invention relates to a phosphate-free cleaning formulation for machine dishwashing, comprising as components: a) 1 to 20% by weight of copolymers of a1) 50 to 93 mol % acrylic acid and/or of a water-soluble salt of acrylic acid, a2) 5 to 30 mol % of methacrylic acid and/or of a water-soluble salt of methacrylic acid and a3) 2 to 20 mol % of at least one nonionic monomer of the formula (I), b) 1 to 50% by weight of complexing agents chosen from the group consisting of glycine-N,N-diacetic acid derivatives and glutamic acid-N,N-diacetic acid and salts thereof, c) 1 to 15% by weight of low-foaming nonionic surfactants, d) 0 to 30% by weight of bleaches and optionally bleach activators, e) 0 to 60% by weight of further builders, f) 0 to 8% by weight of enzymes, g) 0 to 50% by weight of one or more further additives, such as anionic or zwitterionic surfactants, bleach catalysts, alkali carriers, corrosion inhibitors, antifoams, dyes, fragrances, fillers, organic solvents and water, where the sum of components a) to g) is 100% by weight.

Cleaning formulations for machine dishwashing comprising hydrophilically modified polycarboxylates

The invention relates to detergent formulations for machine dishwashing which comprise copolymers having sulfonic acid and carboxylic acid functions, and to a method of using of such copolymers in machine dishwashing.

Detergent formulation for machine dishwashers

A phosphate-free detergent formulation for machine dishwashing is provided. The formulation contains as main components: copolymers of a monoethylenically unsaturated monocarboxylic acid and/or of a salt thereof, and an alkoxylated, monoethylenically unsaturated monomer, wherein the copolymer has a mean molecular weight Mof from 30 000 to 500 000 g/mol and a K value of from 40 to 150, measured at pH 7 in 1% by weight aqueous solution at 25&#xb0; C.; complexing agents; low-foaming nonionic surfactants; bleaches and, optionally, bleach activators; further builders; enzymes; and one or more further additives.
