Definitions

  • the present invention relates to a dishwashing detergent based on a crystalline alkali layer silicate.
  • Detergent mixtures are known as agents for machine washing dishes, which contain sodium tripolyphosphate as a builder, sodium metasilicate as an alkali carrier, chloroisocyanurate as an active chlorine carrier or alkali perborates, persulfates and percarbonates as an active oxygen carrier and low-foaming block polymers with ethylene and propylene oxide groups or modified fatty alcohol oxide groups as modified as surfactants.
  • the cleaning agent mixtures can further comprise alkali metal citrates or aminopolycarboxylic acids.
  • the pH value of the detergent mixtures in a concentration of 1 percent by weight is at least 10 and occasionally up to 12 (see DE-OS 21 42 055, DE-AS 20 62 465).
  • the phosphate-free dishwashing detergent according to DE-OS 36 27 773 contains a crystalline alkali layer silicate in conjunction with a co-builder, for example acrylic acid polymers, polycarboxylates, maleic acid copolymers or vinyl ether carboxylates, in addition to an alkali carrier, a surfactant and an active chlorine carrier, with sodium metasilicate, sodium carbonate or sodium hydroxide as the alkali carrier is used.
  • a co-builder for example acrylic acid polymers, polycarboxylates, maleic acid copolymers or vinyl ether carboxylates
  • an alkali carrier for example acrylic acid polymers, polycarboxylates, maleic acid copolymers or vinyl ether carboxylates
  • a surfactant and an active chlorine carrier with sodium metasilicate, sodium carbonate or sodium hydroxide as the alkali carrier is used.
  • a disadvantage of the known agents is that they only develop their full cleaning action if their content of alkali carrier is so large that the pH in the cleaning liquor is at least 11, which is with regard to the corrosive effect on skin and eyes is dangerous.
  • dishwashing detergent which, with good cleaning power, has the lowest possible pH in its cleaning liquor.
  • the dishwashing detergent contains a crystalline, largely water-insoluble sodium sheet silicate with a SiO2 / Na2O molar ratio of (1.9 to 3.5): 1 in combination with a proton donor, a 0.5 percent by weight aqueous solution of the dishwashing detergent has a pH of less than 10.
  • the dishwashing detergent according to the invention contains 20 to 60% by weight of the crystalline layered silicate 10 to 40% by weight of the proton donor 1 to 2% by weight of a surfactant 1 to 30% by weight of an active chlorine or active oxygen carrier 0 to 7% by weight of a dispersant 0 to 50% by weight of an alkali phosphate and / or 0 to 40% by weight of a filler.
  • Proton donors in the dishwasher detergent according to the invention are polycarboxylic acids such as fumaric, adipic and glutaric acid, hydroxypolycarboxylic acids such as citric acid and tartaric acid and phosphonic acids such as 1-hydroxyethane-1,1-diphosphonic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid, Amino-tri- (methylenephosphonic acid), ethylenediaminetetra- (methylenephosphonic acid), 3-tert.alkyl-3-oxo-1-aminopropane-1,1-diphosphonic acid, 3-tert.alkyl-3-oxo-1-hydroxypropane-1, 1-diphosphonic acid and ⁇ -dimethylaminoalkane-1-hydroxy-1,1-diphosphonic acids are suitable.
  • polycarboxylic acids such as fumaric, adipic and glutaric acid
  • hydroxypolycarboxylic acids such as citric acid and tartaric acid
  • acids their water-soluble acid salts can also be used.
  • mineral acids, their acidic salts and esters such as monosodium dihydrogen monophosphate, monopotassium dihydrogen monophosphate, disodium dihydrogen diphosphate, acidic esters of phosphoric acid, sodium hydrogen sulfate and sodium hydrogen carbonate can be used as proton donors.
  • sodium sulfate as a filler sodium triphosphate as a builder, polymeric or copolymeric polycarboxylic acids or their water-soluble salts as a dispersant, block polymers of long-chain aliphatic alcohols with ethylene oxide or propylene oxide groups or modified fatty alcohol polyglycol ethers as surfactants, and sodium alkali metal sulfate, as an active chlorine carrier or Percarbonate and peroxycarboxylic acids and their salts such as dodecane peroxidicarboxylic acid or magnesium peroxiphthalate can be included.
  • the dishwashing detergent according to the invention is notable for good cleaning properties even in the case of critical soiling, such as burnt-on protein-containing food residues. Furthermore, it shows a high chlorine or active oxygen stability and causes a relatively low corrosion of sensitive washware.
  • the dishwashing detergent according to the invention is preferably used in household dishwashers, but can also be used in commercial dishwashers.
  • the concentration of the powdered dishwashing detergent according to the invention in the cleaning liquor is 3 to 10 g / l, preferably 4 to 5 g / l.
  • the pH value that can be achieved in the cleaning liquor according to the invention in its cleaning liquor is primarily dependent on the concentration ratio of layered sodium silicate to proton donor. It would now be obvious to combine free layered silica with alkalis in order to maintain the same pH value in the cleaning liquor. It has been found, however, that despite the same pH in the cleaning liquor in the case of the combination of layered silica / alkalis, the cleaning success achieved with the dishwashing detergent according to the invention cannot be achieved.
  • aqueous dishwashing solutions The pH of aqueous dishwashing solutions was determined as follows: 10 g of the dishwashing detergent were weighed into a 100 ml volumetric flask, 80 ml of demineralized water were added and the mixture was stirred vigorously for 1 hour at room temperature using a magnetic stirrer, but avoiding foaming. After removing the magnetic stirrer, the volumetric flask was filled to the mark with demineralized water, the solution was mixed and immediately centrifuged. The pH measurements were made immediately afterwards with a glass electrode.
  • a comparison of the cleaning indices shows that the dishwashing detergents according to the invention have comparable cleaning successes in comparison to prior art formulations, despite a considerable reduction in the pH in the washing liquors.
  • Porcelain plates and cups served as ballast to fill up the prescribed amount of 12 items to be washed according to DIN 44 990, part 100 (draft, December 1981).
  • a scale divided into 5 levels was used to assess the damage, according to which the tests were evaluated visually after 125, 250, 500 and 1000 rinsing cycles.
