Abstract

The invention relates to a process for the washing of laundry, in particular, working clothes, in which the laundry is washed in a conventional washing machine for commercial washes with a liquid to pasty surfactant combination which contains (a) 20 to 80 % by weight of alcohol ethoxylates derived from primary C12-C22 alcohols which are linear or methyl-branched in position 2, which alcohols all have an average of 5 or more ethylene oxide groups (EO), and (b) 80 to 20 % by weight of alcohol alkoxylates derived from primary C12-C22 alcohols which are linear or methyl-branched in position 2, which alcohols all have an average of 4 to 8 ethylene oxide groups and 3 to 8 propylene oxide groups (PO). The waste water is treated by way of a diaphragm system and, when treated, can be reused in the washing process.
