After the intended exposure time, it can be mixed with water be rinsed off.
  • EP-B-265 979 discloses thickening premixes for the preparation of thickened aqueous single-phase detergents known from 0.1 to 10 wt .-% of a surfactant, for example a tertiary Amine oxide, and 0.01 to 3 wt .-% of an organic anionic sulfonate exist.
  • EP-A-595 590 teaches aqueous concentrates a viscous cleaning solution when diluted with water result and the tertiary amine oxides, anionic surfactants on sulfate or Sulfonate base, hydrophobically modified polymer surfactants, diluents such as lower alcohols or lower Contain alkyl ethers and alkalis.

Amine oxides in which R 1 is an alkyl group mixture of oleochemical origin are preferred in the context of the present invention. Those amine oxides in which the substituents R 2 and R 3 are 2-hydroxyethyl are particularly preferred. Examples of such amine oxides are bis (2-hydroxyethyl) cocosamine oxide, bis (2-hydroxyethyl) tallow amine oxide and bis (2-hydroxyethyl) stearylamine oxide.
  • Alkyl polyglycosides represent a newer nonionic class of surfactants, the alkyl groups of which come from native fats, oils or petrochemically produced alcohols and the sugar residues of which are derived from hydrolytically split polysaccharides.
  • the alkyl polyglycosides are etherification products of fatty alcohols of oleochemical or petrochemical origin with mono- or oligosaccharides, and the sugar residues can additionally be alkoxylated with the fatty alcohols prior to etherification. This gives alkyl polyglycosides of the general formula (II), which are described, for example, in WO 86/05199.

At this dilution with water increases the viscosity of the cleaning agent at least approximately by a factor of 2, preferably by a factor of 5 to more than 10.
  • the invention Purpose achieved that the agent is easily pumpable as a concentrate is, however, when diluted to the application concentration Viscosity increases and therefore longer on the surfaces to be cleaned is liable.
  • Mixing with water is preferably done using a mixing nozzle that the detergent and water in the desired Quantity ratio are fed separately. That in the Nozzle of detergent mixed with water is applied to the detergent to be cleaned Sprayed on surfaces or by additional air supply to the Mixing nozzle foamed. The desired one occurs during application Increase in viscosity. After the exposure time this can be done with Dilute detergent from the cleaned surfaces with water Water to be washed off.
  • mixing the detergent with water in a mixing container, after which the thickened solution, for example manually applied to the surfaces to be cleaned can be what, for example by means of a cloth, a Sponge, a brush, a spray bottle or a roller can.
