A fabric care composition contains a fabric softening active and a carrier. The fabric softening active may contain a mixture of quaternary nitrogen compounds of general formula (II) where each R1 is independently selected from the group consisting of ethyl, propyl, isopropyl, or butyl; each R2 is independently selected from the group consisting of a saturated C1-22 alkyl group, or an unsaturated C1-22 alkyl group; each R3 is independently selected from the group consisting of a saturated C1-22 alkyl group, or an unsaturated C1-22 alkyl group; each n is independently from about 1 to about 25; m is from 0 to 4; o is from 0 to 4; m + o = 4; and X<-> is an anion. The mixture of quaternary nitrogen compounds contains at least about 5 % mono-ester quaternary nitrogen compound with m = 1 and o = 3, at least about 15 % di-ester quaternary nitrogen compound with m = 2 an o = 2, and at least about 5 % tri-ester quaternary nitrogen compound with m = 3 and o = 1. Also, a novel quaternary nitrogen compound has the above formula, where m = 4 and o = 0. Novel processes may be used to make these quaternary nitrogen compounds. |
