A stable, concentrated (pre-dilute) aqueous fabric softening composition having a viscosity of from 300 to 1000, preferably 300 to 850, more preferably 400 to 800 mPa.s at 116 s-1 which composition is capable of being diluted with water in a 3:1 weight ratio of water:softening composition such that the resulting diluted softening composition is physically stable and has a viscosity of from 40 to 100 mPa.s at 116 s-1, preferable 50 to 90 mPa.s at 116 s-1, the composition comprising a) a cationic fabric softener b) 0.7 to 2.5 % by weight of a cationic cross-linked polymer that is desirable from the polymerization of from 5 to 100 mole percent of cationic vinyl addition monomer, from 0 to 95 mole percent of acrylamide and from 50 to 1000 ppm, preferably 350 to 1000 ppm, more preferably 500 to 1000 ppm of a difunctional vinyl addition monomer cross-linking agent, c) from 0.001 to 0.2 by weight of electrolyte.

L'invention concerne une composition aqueuse concentrée (pré-diluée), stable, assouplissant les textiles ayant une viscosité allant de 300 à 1000, de préférence de 300 à 850, de façon plus particulièrement préférable de 400 à 800 mPa.s à 116 s-1, ladite composition pouvant être diluée avec de l'eau en proportion en poids eau:composition assouplissante de 3:1 de façon à ce que la composition assouplissante diluée résultante soit physiquement stable et ait une viscosité allant de 40 à 100 mPa.s à 116 s-1, de préférence de 50 à 90 mPa.s à 116 s-1, ladite composition comprenant a) un assouplissant textile cationique, b) 0,7 à 2,5 % en poids d'un polymère réticulé cationique souhaitable qui provient de la polymérisation de 5 à 100 pour cent en moles d'un monomère d'addition vinylique cationique, de 0 à 95 pour cent en moles d'acrylamide et de 50 à 1000 ppm, de préférence de 350 à 1000 ppm, de façon plus particulièrement préférable de 500 à 1000 ppm d'un agent de réticulation du monomère d'addition vinylique difonctionnel, c) de 0,001 à 0,2 % en poids d'électrolyte.
