  • Patent number: 6995131
    Abstract: Clear, or translucent fabric softener compositions comprise fabric softener compound, principal solvent system, and high electrolyte levels. The high electrolyte level allows for a broader range of principal solvents to be used and/or reduces the incidence of increased viscosity when low levels of principal solvent are used. Phase stabilizers which are primarily ethoxylated hydrophobic materials can be used to reduce the amount of principal solvent that is needed and/or to stabilize the compositions in the presence of the highest levels of electrolyte. Specific phase stabilizers provide additional benefits including improved softening. Specific electrolytes provide improved results. Addition of primary solvents and/or phase stabilizers to the softener compounds can improve the viscosity/handling of the compounds and the ability to create the finished compositions.

  • Patent number: 6946501
    Abstract: A film-forming composition for use in preparing water-soluble films that are rapidly dissolving under cold water conditions, the composition comprising a water soluble polymer material such as polyvinyl alcohol and a principal solvent, typically diol(s) or derivative of a diol. Films made from the film-forming compositions may be used to encapsulate a variety of compositions for subsequent release into an aqueous medium. Encapsulated compositions can include various laundry detergents and additives, fabric care compositions such as fabric softening compositions and dishwashing detergents among others. When used to encapsulate compositions, the solvent system used in the film-forming composition will have at least one common solvent material as the solvent system used in the encapsulated composition to improve film dissolution and to prevent problems associated with solvent migration.

  • Patent number: 6855229
    Abstract: Disclosed is a composition for softening a wet laid cellulosic structure. A particularly preferred structure is an absorbent tissue. Further disclosed are 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. Also disclosed is a method of using the compound by adding it at a use concentration to the wet end of a papermaking process.
