FABRIC SOFTENER COMPOSITIONS

摘要

An improved fabric softening composition is provided by the synergistic combination of a cationic softening agent and a higher alkyl sulphonate. 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) sulphonates are the C14 to C22 paraffin sulphonates. The preferred ratio of cationic compound to paraffin sulphonate ranges from 5:1 to 12:1 on a weight basis. The preferred form of the composition is as an aqueous dispersion containing from 2 to 5% by weight of cationic compound and 0.2 to 1% paraffin sulphonate. 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.
