A stable structured liquid laundry detergent composition is provided which is particularly effective for removing oily soils from fabrics. The detergent composition comprises, by weight: (a) from about 10% to about 20% of a linear alkyl benzene sulfonate anionic surfactant; (b) from about 0% to about 10% of an alkyl ether sulfate anionic surfactant; (c) from about 5% to about 30% of an alkali metal phosphorous-containing builder; (d) from about 2% to about 15% of sodium carbonate; the total amount of components (c) plus (d) in the detergent composition being at least about 10%; (e) from about 0.1% to about 5% of an ethoxylated amine quaternary cationic surfactant having the following structural formula: wherein R1 represents a linear branched or substituted C8-C18 alkyl, alkaryl, aryl, alkenyl or ether moiety; R2 represents an alkyl group containing from 1 to 3 carbon atoms or a benzyl group; each of x and y are integers which can vary independently from 1 to 8 and the sum of x plus y is greater than 2 and less than 9; and X represents a water-soluble anion; and (f) balance water, said structured liquid detergent composition being free of a nonionic surfactant, and wherein the respective amounts of each of the components (a) through (e) is selected to provide a stable structured liquid composition. |
