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.

L'invention concerne des compositions de traitement du linge présentant une acceptation par les consommateurs améliorée, par exemple, par rapport aux propriétés de phase et/ou par rapport à l'atteinte de l'acceptation d'odeur élevée sans utilisation excessive de parfum. L'invention concerne une composition détergente pour le linge, comprenant un composant contenant de l'azote non enzymatique pouvant présenter une impureté amine à chaîne courte et comprenant un système solvant pouvant favoriser la dissolution dudit composant contenant de l'azote tout en réduisant au minimum la tendance dudit système solvant à créer des odeurs atypiques dues aux impuretés amines. La composition comprend : le composant contenant de l'azote non enzymatique, ledit composant comprenant moins d'environ 10 ppm de l'impureté amine à chaîne courte ; et le système solvant ; la composition satisfaisant également au moins une des conditions suivantes : (i) la composition est sensiblement dépourvue d'enzyme ; (ii) la composition comprend une préparation enzymatique compatible ; (iii) la composition comprend un agent destiné à atténuer les odeurs ; (iv) la composition est sensiblement dépourvue de phases condensées pouvant décomposer ledit composé contenant de l'azote non enzymatique dans la composition détergente pour produire des impuretés amines à chaînes courtes ; et/ou (v) ledit composant contenant de l'azote non enzymatique est purifié avant incorporation dans ladite composition détergente pour le linge liquide.
