Definitions

  • the present invention relates to dishwashing detergents, in particular those for machine dishwashing, which contain sodium silicate as a builder and also co-builders and active chlorine carriers and which are free of phosphates.
  • dishwashing detergents for the automatic washing of household dishes or crockery and cutlery in commercial canteen kitchens contain, as components, builders, alkali carriers, active chlorine carriers, surfactants, perfumes and, if appropriate, fillers.
  • Polyphosphates preferably sodium triphosphate (NTPP), as alkali carriers of water-soluble silicates, preferably sodium metasilicate, caustic soda or sodium carbonate, as active chlorine carriers either chlorine bleach or products from the series of chloroisocyanurates and as surfactants are low-foaming, chlorine-stable block polymers with ethylene and propylene oxide groups modified fatty alcohol polyglycol ether used.
  • NTPP sodium triphosphate
  • alkali carriers of water-soluble silicates preferably sodium metasilicate, caustic soda or sodium carbonate
  • active chlorine carriers either chlorine bleach or products from the series of chloroisocyanurates and as surfactants are low-foaming, chlorine-stable block polymers with ethylene and propylene oxide groups modified fatty alcohol polyglycol ether used.
  • DE-A1-34 13 571 already describes crystalline layered sodium silicates for water softening, which have the composition NaMSi x 0 2x + 1 . y correspond to H20, where M is sodium or hydrogen, x is 1.9 to 4 and y is 0 to 20.
  • co-builder 0.1-3% by weight is used if this is preferably in dry, powdery form and 0.3-7.5% by weight if this co-builder is in liquid form.
  • Polycarboxylates such as polyacetal carboxylates or maleic anhydride-acrylic acid copolymers or maleic anhydride-methylene vinyl ether or their sodium salts, are preferably suitable as co-builders.
  • the other dishwashing components such as fillers, alkali carriers, surfactants and active chlorine carriers and, if appropriate, perfumes, can be substances which are already sufficiently known for these purposes.
  • sodium sulfate as fillers preferably in anhydrous form, sodium carbonate, caustic soda or water-soluble alkali silicates as alkali carrier, chlorine-stable block polymers of long-chain aliphatic alcohols with ethylene oxide or propylene oxide groups or modified fatty alcohol polyglycol ethers as surfactants and sodium dichloroisocyanurate or bleaching liquor as active chlorine carriers.
  • the phosphate-free mixtures according to the invention are notable for very good cleaning action, extremely low corrosion on the items to be washed or the machine and for high chlorine stability.
  • the powdery mixtures are free-flowing even after months of open storage in the laboratory air (see Table 2 below).
  • phyllosilicates used according to the invention have the favorable property of not or only slightly abrasive, which in particular enables gentle rinsing of glasses.
  • a comparison of the cleaning indices shows that, on average, standard cleaning successes are achieved, and the working pH can even be reduced by 0.5 to 1 step.
  • White porcelain plates and cups, stainless steel cutlery from various manufacturers and glasses of various compositions and shapes were tested as items to be washed.
  • a table divided into 5 damage levels is used to determine any damage, and after visual evaluation of the tests after 125, 250, 500 and 1,000 rinse cycles was used to make a judgment.
  • Formulations A, B, C, D and E were used for the corrosion test.
  • the average damage ratings found for 500 wash cycles are shown in Table 3.
  • An automatically operating household machine was used as the machine, which opens the machine door for 1 hour between each washing cycle so that the items to be washed dry completely.
  • the water hardness was between 2 ° and 7 ° d, the rinse temperature at 62 - 66 ° C, the total amount of water per rinse cycle is 28 I, of which approx. 6 I in the cleaning cycle with a dosage of 30 g detergent and 3 ml rinse aid in the rinse cycle .
