CA 2505535

The present invention relates a unit dose fabric treatment product comprising a non-aqueous liquid fabric treatment composition contained in a single compartment water-soluble pouch. The inner space of the pouch contains (A) a cleaning system comprising more than 5% by weight of the fabric treatment composition of at least one surfactant; (B) a fabric softening system comprising at least one fabric softening active selected from the group consisting of (i) cationic ammonium-based fabric softening compounds comprising at least one carbonyl functionality; wherein the molar ratio of anionic surfactant to ammonium-based fabric softener is at least 3:1; (ii) cationic guar gums with a charge density between 0.2 meq/gm to 5.0 meq/gm; and (iii) mixtures thereof. The invention further relates to a method of producing such compositions and to the use of such compositions to impart fabric- cleaning and fabric-softening benefits via single compartment water-soluble pouches to fabric treated therewith.

L'invention concerne un produit de traitement de tissu en dose unitaire comprenant une composition de traitement de tissu liquide non aqueuse conditionnée en pochette hydrosoluble à compartiment unique. L'espace interne de la pochette renferme (A) un système de nettoyage qui comporte, en poids de composition, plus de 5 % d'au moins un tensioactif; (B) un système adoucisseur de tissu comportant au moins un principe actif d'adoucissement qui appartient au groupe constitué par (i) les composés adoucisseurs de tissu cationiques à base d'ammonium ayant au moins une fonctionnalité carbonyle, le rapport molaire entre tensioactif anionique et adoucisseur de tissu à base d'ammonium équivalant au moins à 3:1; (ii) les gommes de guar cationiques ayant une densité de charge comprise entre 0,2 meq/gm et 5 meq/gm; et (iii) leurs mélanges correspondants. L'invention concerne également un procédé relatif à la production de telles compositions et à leur utilisation pour conférer des avantages de nettoyage et d'adoucissement de tissu par un conditionnement en pochettes hydrosolubles à compartiment unique.
