Stable aqueous fabric softening compositions based on water-dispersible cationic fabric softeners such as the di-long chain, di-should chain quaternary ammonium salts are provided using a combination of fatty alcohol and cationic water-soluble polymer to improve the rheological properties to enhance the softening performance. Both concentrated and ready-for-use formulations can be prepared. The active ingredients concentration in the concentrated formula is generally in the range of 11 to 20% by weight while for the ready-for-use formulations, concentration of the active ingredients may range from about 3 to about 8% by weight. In either case, the weight ratio of cationic softening agent to fatty alcohol may range from about 100:1 to about 1:1 and the ratio of cationic softener to cationic water-soluble polymer may range from about 100:1 to 1:1. These compositions have medium viscosity and are easily dispersible. Methods for making the compositions are also disclosed.
