DISHWASHING FORMULATION COMPRISING A MIXTURE OF HYDROPHOBICALLY MODIFIED POLYCARBOXYLATES AND HYDROPHILICALLY MODIFIED POLYCARBOXYLATES

摘要

The present invention relates to a phosphate-free detergent formulation for a dishwashing machine comprising as components a) a) to g) of 100% by weight: wherein a) 1 to 20% by weight of a mixture of the following hydrophobically modified polycarboxylate a1) and a hydrophilic modified polycarboxylate a2), wherein the sum of a1) and a2) is 100% a1) a11) monoethylenically unsaturated C ₃ -C ₁₀ - monocarboxylic acid or a C ₃ -C ₁₀ - dicarboxylic acid or one or more monomers of 20 to 80 mol% is selected from the group consisting of anhydride thereof, a12) from 0 to 80 mol% of one or more monomers of the general formula (I) Wherein R ¹ , R ² and R ³ are each independently H, CH ₃ or C ₂ H ₅ and R ⁴ is a linear, branched or cyclic radical having from 1 to 6 carbon atoms or a radical of from 6 to 12 Lt; / RTI carbon atoms, and a13) 0 to 20 mol% of one or more additional monomers selected from the group consisting of olefins having 10 or more carbon atoms or mixtures thereof and reactive polyisobutene having an average of 12 to 100 carbon atoms From 5 to 95% by weight of a hydrophobically modified polycarboxylate, a2) a21) 50 to 99 mol% of a water-soluble salt of acrylic acid and / or acrylic acid, a22) 0 to 50 mol% of further acidic monomers and / or water-soluble salts thereof, a23) 0.1 to 20 mol% of at least one nonionic monomer of the formula (II) (Wherein R ⁵ is hydrogen or methyl, Z is -C (O) O- or -CH ₂ O- and R ⁶ is the same or different branched or unbranched C ₂ -C ₄ -alkylene radical , R ⁷ is a branched or unbranched C ₁ -C ₆ - alkyl, n is from 3 to 50 Im) From 5 to 95% by weight hydrophilic modified polycarboxylate, b) from 0 to 50% by weight of a complexing agent, c) 0.1 to 20% by weight of a low foaming nonionic surfactant, d) from 0.1 to 30% by weight of bleach and, if appropriate, bleach activator, e) from 0 to 60% by weight of additional builders, f) 0 to 8% by weight of enzyme, g) from 0 to 50% by weight of at least one further additive.
