Definitions

  • the invention is in the field of cleaning agents for hard surfaces and relates to wet wipes impregnated with a special species of a nonionic surfactant are.
  • wet wipes are textile fabrics or tissue papers that are soaked in a cleaning liquid.
  • wet wipes which contain mineral oil, fatty acid esters, fatty alcohol ethoxylates and fatty alcohols.
  • a disadvantage of using these wet wipes is that the surfactants used leave a residue in the form of streaks, which makes the treated surface appear less shiny or even dirty.
  • a first object of the present invention was therefore to provide wet wipes using special surfactants which are free from the problems described at the outset. For logistical reasons, the use of concentrates for the preparation of the impregnation solutions for the wet wipes is advantageous. The disadvantage is that the concentrates often show a tendency to foam when diluted.
  • a further object of the invention was therefore to provide surfactants which can be used to produce concentrates which, due to their viscosity, storage stability, low foaming when diluted and rapid dilutability, permit technically simple and therefore inexpensive production of the wet wipes.
