DETERGENT FORMULATIONS FOR DISHWASHING DISHES CONTAINING A MIXTURE OF POLYCARBOXYLATES WITH HYDROPHUGE MODIFICATION AND POLYCARBROXYLATES WITH HYDROPHYL MODIFICATION.

摘要

Phosphate-free detergent formulations for machine dishwashing containing as components: a) 1 to 20% by weight of a mixture of polycarboxylates with hydrophobic modification a1) and polycarboxylates with hydrophilic modification a2) of a1) 5 to 95% in weight of polycarboxylates with hydrophobic modification 1 of a11) 20 to 80 mol% of at least one monomer of the group consisting of mono- or dicarboxylic acids of C3-C10, monoethylenically unsaturated or their anhydrides, a12) 0 to 80 mol% of at least a monomer of the general formula (I), where R 1, R 2 and R 3 mean, independently of each other, H, CH 3 or C 2 H 5, R 4 means a linear, branched or cyclic residue with 1 to 6 carbon atoms or a aromatic residue with 6 to 12 carbon atoms, and a13) 0 to 20 mol% of at least one other monomer selected from the group consisting of olefins with 10 or more carbon atoms or their mixtures and polyisobutenes reactive with 12 to 100 atoms of carbon e n average. a2) 5 to 95% by weight of polycarboxylates with hydrophilic modification II of a21) 50 to 99% molar of acrylic acid and / or a water soluble salt of acrylic acid, a22) 0 to 50% molar of another acidic monomer and / or a water soluble salt thereof, a23) 0.1 to 20 mole% of at least one non-ionic monomer of the general formula (II), in which the variables have the following meaning: R 5 means hydrogen or methyl, Z means -C (O) O- or -CH2O R 6 means C2-C4 alkylene residues, the same or different, unbranched or branched, R 7 means C1-C6 alkyl, linear or branched, n means 3 to 50, in which case the sum of a1) and a2) results in 100% by weight, b) 0 to 50% by weight of complex former, c) 0.1 to 20% by weight of nonionic surfactants that are weakly foamed , d) 0.1 to 30% by weight of bleach and, optionally, bleaching activators, e) 0 to 60% by weight of other detergent builders, f) 0 to 8% by weight of enzymes, g) 0 to 50% by weight of one or more additives such as anionic or zwitterionic surfactants, bleaching catalysts, alkaline carriers, corrosion inhibitors, antifoams, dyes, fragrant substances, fillers, organic solvents and water, in which case The sum of the components a) to g) results in 100% by weight.
