    • A synergistic mixture for promoting soil release from fabric, under laundry washing conditions, which comprises a polyacrylate polymer and at least one water soluble modified cellulose ether. The polyacrylate polymer comprises: (i) 90 - 100 weight % of polymerized units derived from acrylic acid and (ii) up to 10 weight % of polymerized units derived from one or more C 3 -C 8 monoethylenically unsaturated carboxylic acids, based on the total weight of said polyacrylate polymer. A laundry formulation is also provided which contains the synergistic mixture in an amount of up to 2 weight %, based on the total weight of the laundry formulation. Also provided are methods of promoting soil release from soiled fabric which involve contacting the soiled fabric with an aqueous solution comprising the above-described inventive synergistic mixture or with the above-described laundry formulation.
    • 一种协同混合物,用于在衣物洗涤条件下促进织物的污垢释放,其包括聚丙烯酸酯聚合物和至少一种水溶性改性纤维素醚。 聚丙烯酸酯聚合物包括:(i)90-100重量%的衍生自丙烯酸的聚合单元和(ii)至多10重量%的衍生自一种或多种C 3 -C 8单烯属不饱和羧酸的聚合单元,基于总重量 的所述聚丙烯酸酯聚合物。 还提供洗衣制剂,其含有基于衣物制剂的总重量的至多2重量%的量的协同混合物。 还提供了促进污染织物的污垢释放的方法,其涉及将污染的织物与包含上述本发明的协同混合物的水溶液或上述洗衣制剂接触。
