Laundry treatment compositions having improved consumer acceptance e.g., in relation to phase properties and/or in relation to accomplishing high odor acceptance without over-perfuming. A liquid laundry detergent composition, comprising a non-enzymatic nitrogen-containing component that is capable of having a short-chain amine impurity, and comprising a solvent system capable of promoting dissolution of said nitrogen-containing component while minimizing the tendency of said solvent system to create amine impurity off-odors: wherein the composition comprises: the non-enzymatic nitrogen-containing component wherein said component is comprises less than about 10ppm of the short-chain amine impurity; and the solvent system; and wherein the composition further comprises at least one of the following conditions: (i) the composition is substantially free of enzyme; (ii) the composition comprises a compatible enzyme preparation; (iii) the composition comprises an odor sweetener; (iv) the composition is substantially free of condensed phases which are capable of decomposing said non-enzymatic nitrogen-containing compound in the detergent composition to produce short-chain amine impurities; and/or (v) said non-enzymatic nitrogen-containing component is purified prior to incorporation into said liquid laundry detergent composition.
