A liquid laundry detergent formulation is described including a surfactant, a polycarboxylate builder and a 2-methyl-1,3-propanediol carrier solvent. A particularly preferred builder comprises a non-hydrophobically modified, acrylic/polyether comb-branched copolymer, wherein the polyether portion comprises moieties derived from at least two constituents selected from the group consisting of ethylene oxide, propylene oxide, and butylene oxide. Preferably, the comb-branched copolymer is made according to a process selected from the group consisting of: (i) copolymerizing an unsaturated macromonomer with at least one ethylenically unsaturated comonomer selected from the group consisting of carboxylic acids, carboxylic acid salts, hydroxyalkyl esters of carboxylic acids, and carboxylic acid anhydrides, and (ii) reacting a carboxylic acid polymer and a polyether prepared by polymerizing a C2-C4epoxide, wherein the carboxylic acid polymer and the polyether are reacted under conditions effective to achieve partial cleavage of the polyether and esterification of the polyether and cleavage products thereof by the carboxylic acid polymer.
