A stable, concentrated (pre-dilute) aqueous fabric softening composition having a viscosity of from 300 to 1000, preferably 300 to 850, more preferab ly 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 t he resulting diluted softening composition is physically stable and has a vi scosity 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 p olymerization of from 5 to 100 mole percent of cationic vinyl addition monom er, from 0 to 95 mole percent of acrylamide and from 50 to 1000 ppm, prefera bly 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 ele ctrolyte.
