Abstract:
1. A composition for softening an absorbent tissue comprising: a) from about 10% to about 60% by weight of a quaternary ammonium softening active ingredient; b) free amine compounds at a level such that the softening composition has a tertiary to quaternary amine ratio of greater than about 0.06 and less than about 0.2; wherein said softening active ingredient is selected from the group consisting of quaternary compounds; mono-, di-, and tri-ester quaternary ammonium compounds, and mixtures thereof and;  wherein said free amine compounds has substantially the same chemical structure as a respective quaternary amine, except that said free amine compounds are not methylated; c) an aqueous vehicle in which said softening active ingredient is dispersed; d) from about 0.01% to about 5% by weight of a high polymer; wherein the high polymer has a weight-average molecular weight of from about 2,000,000 to about 25,000,000; and e) from about 1% to about 20% by weight of a bilayer disrupter; wherein the bilayer disrupter is a nonionic surfactant derived from saturated and/or unsaturated primary and/or secondary, amine, amide, amine-oxide fatty alcohol, fatty acid, alkyl phenol, and/or alkyl aryl carboxylic acid compounds, and have from about 6 to about 22 carbon atoms in a hydrophobic chain.
