  • Paper softening compositions containing bilayer disrupter
    Patent number: 7282116
    Abstract: Disclosed is a composition for softening an absorbent tissue. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: (R1)4?m—N+—[(CH2)n—Y—R3]mX? the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant.

  • Soft tissue paper having a softening composition containing bilayer disrupter deposited thereon
    Patent number: 6607637
    Abstract: Disclosed is a composition for softening an absorbent tissue and tissue structures softened using the composition. The composition includes an effective amount of a softening active ingredient; a vehicle in which the softening active ingredient is dispersed; an electrolyte dissolved in the vehicle; and a bilayer disrupter. The electrolyte and the bilayer disrupter cooperate to cause the viscosity of the composition to be less than the viscosity of a dispersion of the softening active ingredient in the vehicle alone. Preferably, the softening active ingredient is a quaternary ammonium compound with the formula: (R1)4−m—N+—[(CH2)n—Y—R3]mX− the vehicle is water, the electrolyte is calcium chloride, and the bilayer disrupter is a nonionic surfactant.
