Definitions

  • the present patent application describes detergents for the automatic cleaning of dishes.
  • the subject of this application are phosphate-free automatic dishwashing detergents.
  • Machine-washed dishes are often subject to more stringent requirements today than manually-washed dishes. So the dishes after machine cleaning should not only be completely free of food particles free but also, for example, no whitish, based on water hardness or other mineral salts stains that come from lack of wetting agent from dried water drops.
  • Modern automatic dishwashing detergents meet these requirements by integrating cleansing, caring, water-softening and clear-rinsing active ingredients and are known to the consumer, for example, as “2in1" or "3in1" dishwashing detergents.
  • As essential for the cleaning as for the rinse aid success constituent intended for the private consumer dishwasher automatic dishwashing contain builders. On the one hand, these builders increase the alkalinity of the cleaning liquor, whereby fats and oils are emulsified and saponified with increasing alkalinity, and on the other hand reduce the water hardness of the cleaning liquor by complexing the calcium ions contained in the aqueous liquor.
  • Particularly effective builders have proved to be the alkali metal phosphates which, for this reason, form the main constituent of the vast majority of commercially available automatic dishwashing detergents.
  • phosphates are highly valued for their beneficial effect as a component of automatic dishwashing detergents, their use is not unproblematic from the environmental point of view, since a substantial portion of the phosphate enters the water via the domestic effluent and especially in stagnant waters (lakes , Barrages) plays a critical role in their over-fertilization.
  • eutrophication the use of pentasodium triphosphate in laundry detergents in a number of countries, e.g. USA, Canada, Italy, Sweden, Norway, significantly reduced by law and regulations. completely prohibited in Switzerland. In Germany, detergents since 1984 may contain no more than 20% of this builder.
  • nitrilotriacetic acid especially sodium aluminosilicates (zeolites) are used as phosphate substitutes or substitutes in textile detergents.
  • these substances are not suitable for use in automatic dishwashing detergents for various reasons.
  • alkali metal phosphates in automatic dishwashing detergents are therefore in the Literature discussed a number of substitutes, of which the citrates are particularly noteworthy.
  • Phosphate-free automatic dishwashing detergents which, in addition to a citrate, furthermore contain carbonates, bleaches and enzymes are described, for example, in the European patents EP 662 117 B1 (Henkel KGaA) and EP 692 020 B1 (Henkel KGaA).

  • the object of the present application was to provide a phosphate-free automatic dishwashing detergent, which is comparable in terms of its cleaning performance and with respect to its rinse results and its performance in terms of inhibition of scale with conventional phosphate cleaning agents or even better.
  • automatic dishwashing detergents which, in addition to citrate, sodium percarbonate and nonionic surfactants, also contain specific hydrophobically modified copolymers have excellent deposit inhibition and excellent cleaning and rinsing performance even with the addition of small amounts of methylglycinediacetic acid and without the addition of alkali metal phosphates.
