A fabric care composition for providing improved colour care to laundered fabrics comprises a polyamine functional polymer and a crystal growth inhibitor selected from the group consisting of carboxylic compounds, organic mono and diphosphonic acids, and salts and complexes thereof, and mixture thereof. In one embodiment, the polyamine functional polymer has a molecular weight between 200 and 10,000 and, when the crystal growth inhibitor is selected from carboxylic acid, organic diphosphonic acid, and mixtures thereof, the crystal growth inhibitor is present in an amount of less than 1 % by weight of the composition. In another embodiment, the crystal growth inhibitor is present in an amount of from 0.005 to 0.2 percent by weight of the composition.

L'invention concerne une composition comprenant un polymère à fonctionnalité polyamino, et stabilisée au moyen d'un inhibiteur de croissance cristalline.
