Patent ID: 7311853

Claim:
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 softening active ingredient is a mono-, di-, or tri-ester quaternary ammonium compound having the formula: (R 1 ) 4-m —N + —[(CH 2 ) n —Y—R 3 ] m X − wherein Y is —O—(O)C—, or —C(O)—O—, or —NH—C(O)—, or —C(O)—NH—; m is 1 to 3; n is 0 to 4; each R 1 is a C 1 -C 6 alkyl or alkenyl group, hydroxyalkyl group, hydrocarbyl or substituted hydrocarbyl group, alkoxylated group, benzyl group, or mixtures thereof; each R 3 is a C 13 -C 21 alkyl or alkenyl group, hydroxyalkyl group, hydrocarbyl or substituted hydrocarbyl group, alkoxylated group, benzyl group, or mixtures thereof; and X − is any softener-compatible anion; 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.
