  • Patent number: 7928053
    Abstract: A multiphase cleaning composition comprises a first phase and a second ionic liquid phase, wherein the second phase is substantially immiscible with the first phase. The first phase may comprise, for example, an aqueous phase or a silicone solvent system. Methods of cleaning a soiled surface comprise contacting a soiled surface with a multiphase wash liquor including a first phase and a second ionic liquid phase, wherein the second phase is substantially immiscible with the first phase, and removing soils from the surface.

  • Patent number: 7776810
    Abstract: Compositions comprising an ionic liquid active composed of an ion active and an ionic liquid-forming counter ion, wherein the ion active is capable of delivering a fabric treating benefit, a surface treating benefit, and/or an air treating benefit. The compositions are substantially free of added water and have a viscosity less than about 5000 mPa·s at room temperature. The compositions are easily diluted with water and/or organic solvent, without formation a gel phase during the dilution process. Various products, especially a unit dose product, made with such compositions are also disclosed.
