Single compartment unit dose fabric treatment product comprising pouched compositions with cationic fabric softener actives
First Claim
1. A unit dose fabric treatment product comprising a non-aqueous liquid fabric treatment composition contained within a single compartment water-soluble pouch, an inner space of said pouch containing (A) a cleaning system comprising more than 5%, by weight of the fabric treatment composition, of at least one anionic surfactant;
- and (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 about 3;
1;
(ii) cationic guar gums with a charge density between about 0.2 meq/gm and about 5.0 meq/gm; and
(iii) mixtures thereof.

Abstract
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.
