Patent ID: 7282116

Claim:
A composition for softening an absorbent tissue, said composition comprising: at least about 30% of said composition of a softening active ingredient; a vehicle wherein said softening active ingredient is dispersed; from about 0.6% to about 25% of an electrolyte dissolved in said vehicle; and from about 0.1% to about 7.5% of a bilayer disrupter, wherein said electrolyte and said bilayer disrupter cooperate to cause the viscosity of said composition to be less than the viscosity of a bicomponent dispersion of said softening active ingredient in said vehicle; wherein said wherein said softening active ingredient comprises a quaternary ammonium compound, selected from the group of quaternary ammonium compounds having the formulas: (R 1 ) 4-m —N + —[R 2 ] m X − A) wherein: m is 1 to 3; 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 2 is a C 14 -C 22 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; (R 1 ) 4-m —N + —[(CH 2 ) n —Y—R 3 ] m X − B) 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 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 group, hydroxyalkyl group, hydrocarbyl or substituted hydro-carbyl group, alkoxylated group, benzyl group, or mixtures thereof; and X − is any softener-compatible anion; wherein each R 1 is a C 1 -C 6 alkyl or hydroxyalkyl group, each R 3 is an C 11 -C 21 hydrocarbyl group, n is 2 to 4 and X − is any softener compatible anion; and mixtures thereof; and wherein said bilayer disrupter is selected from the group consisting of nonionic surfactants derived from saturated and/or unsaturated primary, secondary, and/or branched, amine, amide, amine-oxide fatty alcohol, fatty acid, alkyl phenol, and/or alkyl aryl carboxylic acid compounds having from about 6 to about 22 carbon atoms in a hydrophobic chain, wherein at least one active hydrogen of said compounds is ethoxylated with ≦50 ethylene oxide moieties to provide an HLB of from about 6 to about 20.
