1. An in-rinse liquid fabric softening composition comprising:
a polymeric quaternary ammonium salt effective as a conditioning agent in an amount of about 0.4% to about 1.2% by weight based on the total weight of the composition, the polymeric quaternary ammonium salt being a polyquaternium material;
water in an amount of 96% to 99.5% by weight based on the total weight of the composition; and
an anti-static agent in an amount of about 0.6% to about 3% by weight based on the total weight of the composition, the anti-static agent including at least a non-polymeric quaternary ammonium salt;
wherein the composition excludes ester quaternary compounds.
