Patent
CA 2425618
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.
