Definitions

  • Phosphate-free detergents with a content of finely crystalline aluminosilicates as a phosphate substitute, sodium carbonate or sodium silicates as washing alkali and polyanionic compounds from the class of the aminoalkane polyphosphonic acids and the homo- or copolymeric polycarboxylic acids derived from acrylic acid, methacrylic acid, maleic acid and olefinically unsaturated, copolymerizable compounds are known.
  • the preferred phosphonic acids or phosphonic acid salts are ethylene diamine tetramethylene phosphonate (EDTMP) and diethylene triamine pentamethylene phosphonate, mostly in the form of their sodium salts.
  • Preferred polymeric polycarboxylic acids are copolymers of maleic acid with vinyl methyl ethers and in particular maleic acid with acrylic acid in a ratio of 1: 5 to 1: 1 with a molecular weight of 10,000 to 150,000. These polyacids are also usually present in the compositions as sodium salts.
  • the amounts of aminoalkanephosphonates used are usually 0.1 to 1% by weight, those of copolymers 3 to 6% by weight, based on the composition.
  • the complexing and retarding properties (so-called threshold effect) of these additives are often not sufficient to limit the formation of fiber incrustations to the desired extent. It has been shown that the incrustations increase with frequent washing of the textiles with hard water and can eventually reach an undesirable extent. This increase in incrustations manifests itself in an increasing hardening and graying of the tissue and can be followed quantitatively by determining the tissue ash.
  • the task was therefore to reduce the tendency to form such incrustations.
  • a detergent that contains less than 0.1% inorganically bound phosphorus is understood to be phosphate-free.
  • An essential feature of the invention is the joint use of the aminoalkane polyphosphonates and / or polymer carboxylic acids listed under (d) together with the hydroxyalkane diphosphonate mentioned under (f). It is true that the use of the hydroxyalkane phosphonate (component f) in washing and cleaning detergents have long been known, but after the aminoalkane phosphonates listed under (d1) or the polymers according to (d2) were found, this compound was not used in modern phosphate-free agents, since the hydroxyalkane phosphonate is known to have a much lower sequestering capacity than the aminoalkane phosphonates according to (d1) and also has practically no threshold properties comparable to the polymers according to (d2).
