The patent specification discloses a method of softening fabrics by agitating them in an aqueous medium containing (a) a heavy duty spray dried built synthetic detergent composition consisting of 10% sodium linear tridecyl benzene sulfonate, 2% of a nonionic detergent which consists of a C14-C15 fatty alcohol condensed with an average of 11 ethylene oxide groups per molecule, 1% of a mixed sodium coconut/tallow (20:80) fatty acid soap, 33% of pentasodium tripolyphosphate, 7% of sodium silicate wherein the ratio of Na2O to SiO2 is 1:2.35, 0.5% sodium carboxymethyl cellulose, with the balance of the detergent composition being optical brighteners, about 38% sodium sulfate, and about 7% moisture; (b) a softening composition consisting of about 20% of distearyl dimethyl ammonium chloride, about 40% of Type A synthetic sodium molecular sieve zeolite having a mean particle diameter of 5.9 to 6.4 microns and containing about 21% water, and about 40% sodium perborate; wherein about 0.1% to about 0.3% by weight of the aqueous medium consists of (a) and (b), and the ratio of (a) to (b) is 2:1.
