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.
