| 摘要 |
A detergent composition is described which is particularly suitable for the mechanical cleaning of hard surfaces, in particular glass, porcelain and the like, in a cleaning liquor which is within the alkaline range. This detergent composition is composed of (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, and (B) a selected quaternary ammonium compound as a cationic surfactant. These compositions are particularly suitable for industrial crockery and bottle washing plants which are operated within the highly alkaline pH range and with vigorous mechanical agitation of the liquor.
