    Abstract: Methods employing detergent compositions effective for reducing soil redeposition and accumulation on hard surfaces are disclosed. The alkaline detergent compositions employ vinylidene diphosphonic acid polymers, including unsaturated monocarboxylic acid polymers with a phosphonate end group, preferably a vinylidene diphosphonic acid end group, in combination with an alkali metal hydroxide or other alkalinity source. The alkaline detergent compositions preferably further employ threshold agents. The alkaline detergent compositions reduce the amount of phosphorus-containing materials and polyacrylate materials required for water conditioning, soil removal and soil antiredeposition.

    Abstract translation: 公开了使用有效减少土壤再沉积和硬表面积聚的洗涤剂组合物的方法。 碱性洗涤剂组合物使用亚乙烯基二膦酸聚合物,包括具有膦酸酯端基的不饱和一元羧酸聚合物,优选亚乙烯基二膦酸端基,与碱金属氢氧化物或其它碱性源组合。 碱性洗涤剂组合物优选进一步使用阈值剂。 碱性洗涤剂组合物减少了水调节,除污和土壤抗再沉积所需的含磷材料和聚丙烯酸酯材料的量。
