Definitions

  • the present application relates to automatic rinse aid rinse aids which must contain certain fatty acid alkanolamide polyalkylene glycol ethers and the use of these amides to improve the drying performance of dishwashing detergents.
  • rinse aid is added to ensure that the water runs as completely as possible from the items to be washed, so that the different surfaces at the end of the washing program are residue-free and shiny.
  • Commercially available rinse aids are mixtures of nonionic surfactants, solubilizers, organic acids and solvents, water and optionally preservatives and fragrances.
  • the object of the surfactants in these compositions is to influence the interfacial tension of the water so that it is as thin as possible, coherent Film can run off the dishes, so that during the subsequent drying process no drops of water, streaks or films remain (so-called net effect).
  • test persons are currently used who visually evaluate the parameters "spotting” and “filming" for cleaned objects, eg plates, glasses, knives, etc. Modern dishwashing detergents, therefore, contain rinse aid to improve the drainage of water from the surfaces of the dishes.
