Definitions

• the invention is in the field of hard surface cleaners and relates to wet wipes impregnated with a particular species of nonionic surfactant.
• wet wipes are textile fabrics or also tissue papers that are soaked with a cleaning liquid.
• wet wipes are textile fabrics or also tissue papers that are soaked with a cleaning liquid.
• 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. It is disadvantageous that the concentrates often show a tendency to foam when diluted.
• the 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.
• the invention relates to wet wipes, which are characterized in that they are impregnated with mixed ethers.
• nonionic surfactants of the mixed ether type preferably in combination with alkyl oligoglucosides
• Impregnation agents based on mixed ethers prove to be low-viscosity and practically foam-free in use. When used, the wet wipes soaked do not leave streaks and do not impair the gloss. Concentrates based on mixed ethers are low-viscosity and particularly low-foaming when diluted to the application concentration.
