FABRIC SOFTENING COMPOSITION. ABSTRACT. An improved fabric softening composition is provided by the synergistic combination of a cationic softening agent and a higher alkyl sulfonate. The preferred cationic compounds are the water-soluble or dispersible (a) di- longchain alkyl - di-shortchain alkyl quaternary ammonium salts and (b) 2-longchain alkyl imidazolinium salts. The preferred alkyl (i.e. paraffin) sulfonates are the C14 to C22 paraffin sulfonates. The preferred ratio of cationic compound to paraffin sulfonate ranges from 5:1 to 12:1 on a weight basis. The preferred form of the composition is as an aqueous dispersion contai- ning from 2 to 5 % by weight of cationic compound and 0.2 to 1 % paraffin sulfonate. A process for making the compositions of the invention is also provided along with a process of treating laundry materials in the rinse cycle of the laundering operation.
