Abstract:
1. A detergent composition comprising: 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 and 2) a sulfonic acid group-terminated (meth)acrylic acid-based polymer, and at least 0.5% by weight of a longer alkyl chain mid-chain branched surfactant compound represented by the following formula: wherein: (a) R is a hydrophobic C9 to C22, as total carbons in the moiety, mid-chain branched alkyl moiety having: (1) a longest linear carbon chain attached to the —X—Y moiety in the range of from 8 to 21 carbon atoms; (2) one or more C (b) Y is a hydrophilic moiety selected from sulfates, sulfonates, amine oxides, and polyoxyalkylenes; and (c) X is selected from —CH
