Abstract
Abstract Stable concentrated aqueous fabric softening compositions based on water-dispersible di-longchain, di-short chain quaternary ammonium salts are provided utilizing ethoxylated amine salts and water-soluble electrolyte. The softening quaternary component comprises from about 12-20% by weight of the composition; the amine salt from about 0.5 to about 10% preferably about 1 to 7% by weight and the electrolyte from about 0.1 to 1.5% by weight. Ratios of quaternary compound to amine salt may vary from about 40:1 to 2:1 and preferably from about 10:1 to 5:1. Methods for making the composition are also described.
