A detergent composition containing at least 0.1% by weight of at least one polymer selected from the group consisting of 1) a polycarboxylic acid-based polymer containing a polyalkylene glycol chain in the structure thereof, 2) a sulfonic acid group-terminated (meth)acrylic acid-based polymer, and 3) an acrylic acid (salt)-maleic acid (salt)-based copolymer having a clay dispersibility under a condition of 50 ppm of calcium carbonate of 0.3 or more; and at least 0.5% by weight of a longer alkyl chain mid-chain branched surfactant compound. The detergent composition can enhance anti-gelling properties to calcium ions, improve the dispersibility to solid particles at low temperatures or under high-hardness conditions, and improve detergency against stains such as mud and carbon black.
一种洗涤剂组合物,其中含有至少 0.1%(按重量计)选自以下组别的至少一种聚合物:1)在其结构中含有聚亚烷基二醇链的聚
羧酸基聚合物;2)
磺酸基团封端的(甲基)
丙烯酸基聚合物;和 3)
丙烯酸(盐)-
马来酸(盐)基共聚物,其在 50ppm
碳酸钙条件下的粘土分散性为 0.3 或以上;以及至少 0.5% (按重量计)的较长烷基链中链支链表面活性剂化合物。该洗涤剂组合物可增强对
钙离子的抗胶凝性,提高在低温或高硬度条件下对固体颗粒的分散性,并提高对污渍(如泥浆和
炭黑)的去污力。
