PCT No. PCT/US94/08593 Sec. 371 Date Jun. 14, 1996 Sec. 102(e) Date Jun. 14, 1996 PCT Filed Jul. 29, 1994 PCT Pub. No. WO95/04184 PCT Pub. Date Feb. 9, 1995The present invention relates to fabric softening compositions of insoluble, degradable cationic fabric softeners at high concentrations. In particular, the present invention addresses the problem of dispersibility which is usually associated with concentrations of biodegradable cationic fabric softeners above 30%. Including a mixture of aromatic acids, especially benzoic acid and salicylic acid, at an amount of at least 10% in total, has proven to eliminate the dispersibility drawbacks and stabilize the high concentration of the fabric softener active.
