Definitions

  • the present invention relates to an aqueous cleaning agent which contains nonionic surfactants and is suitable for cleaning in the sanitary field.
  • the pH of acidic cleaning agents is usually between 0 and 2. Such a low pH makes special demands on the stability of the components.
  • the thickeners used to increase the viscosity e.g. Amines or amine dehvates often supply products that are not stable in viscosity for a sufficient period of time.
  • the viscosity of the products can vary greatly as a function of the storage temperature.
  • Other typical thickeners such as guar flour, xanthan gum or cellulose derivatives are not stable in acidic media and quickly lose their thickening properties. Another disadvantage of these compounds is that they make no contribution to the cleaning performance of the cleaning agents.
  • the thickeners used in neutral and alkaline detergents mean that the detergents dissolve only with difficulty in water in the event of a dilution process which may be provided. In addition to the aforementioned thickeners, this disadvantage can also be observed with synthetic polymers.
  • nonionic surfactants especially tertiary amines, used as thickeners in sanitary cleaners.
  • their storage stability is not sufficient.
  • DE-OS 35 42 970 describes a sanitary cleaning agent which contains alkyl ether sulfates, amphoteric surfactants or mixtures of nonionic surfactants with oxyethylated amines as thickeners.

  • the present invention relates to aqueous cleaning agents which contain a surfactant mixture of nonionic surfactants from a) Ci 2 -C 22 alcohol alkoxylates with a degree of alkoxylation between 6 and 15, b) C 2 -C 22 alcohol alkoxylates with a degree of alkoxylation between 2 and 5 and c ) C ⁇ o-C 15 oxo alcohol alkoxylates with a degree of alkoxylation between 5 and 15, and
  • the surfactant mixture of the non-ionic surfactants a, b, and c namely fatty alcohol alkoxylates with different degrees of alkoxylation and oxo alcohol alkoxylates, has a thickening effect in cleaning agents.
