Stable concentrated aqueous fabric softening compositions based on water-dispersible di-long chain, di-short chain quaternary ammonium salts are provided utilizing ethoxylated amine salts and water-soluble electrolyte. The softening quaternary component of the general formula <IMAGE> wherein R<1>, R<2>, R<3> and R<4> each independently represent a C1-30 aliphatic radical with at least two of R<1>, R<2>, R<3> and R<4> being an alkyl group of C14 to C30 comprises from about 12-20% by weight of the composition; the amine salt from about 1 to about 5% and the electrolyte from about 0.5 to 5% by weight. Ratios of quaternary compound to amine salt may vary from about 40:1 to 2:1. Methods for making the composition are also described. |
