- the demulsifying effect of these cleaning agents known from the prior art is unsatisfactory with regard to today's requirements. This means that the demulsification of the removed oil-containing impurities or the subsequent oil separation resulting therefrom is not sufficient to lower the residual oil values in the wastewater to the low values required today.
- the demulsifying action of the cleaning agents should result in improved oil separation and thus lower residual oil values in the waste water.

- the demulsifying cleaning agents according to the invention have an excellent cleaning potential. Due to the good demulsifying effectiveness of these cleaning agents, the removed oil-containing contaminants separate themselves when the aqueous application solution is diluted. Fats and oils washed off the substrate surfaces in this way can be easily and easily removed from aqueous media, for example using simple oil separators. In this way, wastewater suitable for receiving water always results.
