Abstract
Abstract A liquid detergent composition is provided having an aqueous layer and a layer of a liquid water-immiscible oily material, which composition when shaken, forms a temporary oil-in-water emulsion. The aqueous layer contains a foam-producing watersoluble organic detergent, a non-emulsifying foam stabilizer, and water.
