Concentrated fabric softening compositions

Claim 1

A concentrated aqueous fabric softener composition which is pourable at 4.4°C (40°F), the composition being characterized by: A. from 2% to 12.5% of a mono nitrogen quaternary ammonium cationic softener salt having the formula wherein R 1 and R 2 can be the same or different and are selected from C 14 to C 20 alkyl and alkenyl groups, R 3 and R 4 can be the same or different and are selected from C 1 to C 3 alkyl or -(C n H 2n O) x H groups wherein n is 2 or 3, x is from 1 to 3, and wherein X - is an anion selected from halide, methylsulfate or ethylsulfate; B. from 5% to 18% of a second cationic softener salt selected from (1) di (2-amido-ethyl)methyl quaternary ammonium salts having the formula wherein R 5 and R 6 can be the same or different and are selected from C 14 to C 20 alkyl and alkenyl groups, wherein R 7 is selected from H, methyl, ethyl and (C n H 2n O) x H wherein n is 2 or 3 and x is from 1 to 5 and wherein X - is selected from halide, ethylsulfate or methylsulfate; (2) imidazolinium quaternary salts having the formula wherein R 8 and R 9 can be the same of different and are selected from C 14 -C 20 alkyl and alkenyl groups, wherein X - is halide, ethylsulfate or methylsulfate; and (3) imidazolinium quaternary salts having the formula wher ei n R 10 and R 11 can be the same or different and are selected from C 14 -C 20 alkyl and alkenyl and X - is halide, methylsulfate or ethylsulfate, provided that in mixtures of the quaternary ammonium salt with at least one of the imidazolinium quaternary salts, either the quaternary ammonium salt or the at least one imidazolinium quaternary salt comprises less than 2% of composition; C. from 0.05% to 0.6% of an inorganic water-soluble ionizable salt; and D. water; wherein the total amount of Components A + B is from 15% to 23%, wherein there is unsaturation present on at least one of Components A or B such that the cationic active system has an Iodine Value of at least 5.7.
