Definitions

  • the present invention relates to a new rinse aid for dishwashers in the form of a solid block which is slowly soluble in water and does not contain any environmentally harmful phosphates.
  • Modern dishwashing detergents have a more or less sophisticated control system in which, in addition to pre-rinsing, the main cleaning cycle, in which the actual washing-up liquid is used at higher temperatures, one or more rinse-aid cycles are added before the cleaned dishes are dried under the influence of heat. Rinsing should remove residues of detergent that still adheres to the dishes from the main wash cycle. When washing with water, however, water droplets remain on the dishes, which form blind spots of calcium and magnesium salts after drying, particularly in areas with hard water.
  • rinse aid to the last rinse water used for rinsing, which on the one hand contains a surfactant which ensures that the rinsing water can run off the dishes as residue-free as possible and on the other hand contains builder substances which bind calcium and magnesium ions and thereby a deposition of the corresponding carbonates on the dishes is prevented or carbonates which have already precipitated are brought back into solution.
  • these rinse aids can also contain agents which give the dishes a surface gloss after drying.
  • the rinse aid is dispensed so slowly that a single fixed block, for example with an edge length of 2.5 cm, is sufficient to ensure perfect rinse aid through several rinse cycles.
  • rinse aid in the form of solid blocks consist of a poorly water-soluble wetting agent, in particular polyoxypropylene-polyoxyethylene block polymer, urea and an additive which is sparingly soluble in water.
  • the rate of dissolution of the wetting agent is promoted by the urea and slowed down by the additive, so that it can be adjusted within further limits.
  • Such builder-free agents are unsuitable for lime-rich water.
  • rinse aids consist of a natural or artificially produced clay, in particular of the hectorite type, a wetting agent and sodium citrate and isopropyl alcohol and water as a solvent.
  • the mixtures are added to the rinsing water as a solution or suspension, although solid addition as a powder, tablet, block or granulate is also considered. The handling of such substances is therefore problematic.
  • biodegradable builder known per se can be used instead of the aforementioned zeolites.
  • B. complexing acids such as citric acid, tartaric acid, malic acid or gluconic acid and low molecular weight polyacrylates can be used.
  • the surfactants used must be as low-foaming as possible in order to allow the rinsing solution to flow away clearly.
  • both cationic and anionic as well as nonionic surfactants can be used.
  • Nonionic surfactants are particularly preferred because of their good degradability, in particular fatty alcohol alkoxylates.
  • the products of the invention may also contain a small amount of dyes or perfumes in order to make the products more attractive to the consumer.
  • Other additives include, for example, chlorine-releasing agents such as sodium dichloroisocyanate, which can bring about additional sterilization of the dishes, electrolyte salts, such as sodium sulfate or sodium chloride, which influence solubility, or other additives known for this purpose, which may also be present in small amounts in the rinse aid according to the invention .
  • Table 1 shows the composition of commercial rinse aid containing phosphates and the composition of several rinse aid according to the invention.
  • the individual rinse aids weigh 45 - 48g and contain traces of a dye (YellowDye) and 1% lemon perfume in addition to the substances listed in the table. Power and degradation speed correspond to the mean values according to the tests in Tables 2 and 3.
  • Table 2 contains the drying performance of the rinse aid tested according to Tab. 1 in a dishwasher compared to porcelain, glass or cutlery.
