<p>- 1 - HOE 80/F 932 of the disclosure: A detergent composition which is particularly suitable for the mechanical cleaning of hard surfaces, in particular glass, porcelain and the like, in a cleaning liquor within the alkaline range, is described. This detergent composition comprises A) a nonionic surfactant selected from the group comprising polyalkylene glycol monoalkyl ethers containing ethylene oxide and propylene oxide units, polyglycol ether formals containing ethylene oxide units and, if appropriate, propylene oxide units, or polyalkylene glycol dialkyl ethers containing ethylene oxide units and, if appropriate, propylene oxide units, B) a selected quaternary ammonium compound as a cationic surfactant, and C) a fluorinated alcohol as an antifoaming agent. These compositions are particularly suitable for industrial crockery-cleaning and bottle-cleaning plants which are operated with considerable mechanical agitation of the liquor within a highly alkaline pH range.</p> |
