  • Publication number: 20030139312
    Abstract: Highly concentrated, preferably clear or translucent, fabric softener compositions comprising at least 40% softener active and less than about 20% water by weight of the composition for dispensing during the rinse cycle of a washing machine or for handwashing. The composition may be a liquid, granule or other standard form that is placed directly in the rinse bath or placed in a dispensing device for delayed dispensing into the rinse bath. Alternatively and preferably, the concentrated composition is incorporated or encapsulated in a unitized article for dispensing in the rinse bath or placement in a dispensing device for subsequent dispensing. The use of these compositions and articles provide added convenience and excellent fabric softening without staining or leaving residue on the fabrics.

  • Publication number: 20030127206
    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; a bilayer disrupter and a high polymer. 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. The high polymer adds “stringiness” to the composition opening the air pressure operating window for spray application of the softening composition.

  • Patent number: 6579416
    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; and an electrolyte dissolved in the vehicle. The electrolyte causes 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, and the electrolyte is calcium chloride.

  • Patent number: 6559117
    Abstract: Viscosity stable, concentrated, aqueous, liquid fabric softening compositions contain a mixture of biodegradable diester quaternary ammonium softening materials and specific co-active fabric softening materials which include substituted imidazoline compounds and specific quaternary ammonium salts.
