Abstract

A process that degasses a structured surfactant composition that comprises at least one surfactant, water, and at least one suspending agent chosen from polysaccharides, gums, and celluloses. By degassing the composition, the suspending agent can form a structured system. Gas, such as air bubbles, disrupts the formation of the structuring system, which reduces the ability of the composition to suspend materials.
