US 11,028,342 B2 · Use of an ionic liquid and alcohol blend to modify the rheology of polyethoxylated alcohol sulfates

Abstract

In one embodiment, a polyethoxylated alcohol sulfate composition is provided which includes a polyethoxylated alcohol sulfate, such as sodium laureth ether sulfate (SLES), water, an ionic liquid, and an alcohol. The ionic liquid and the alcohol form a synergistic blend, enabling a significant reduction of the viscosity of the polyethoxylated alcohol sulfate composition. Also provided is an embodiment of a method for modifying the rheology of polyethoxylated alcohol sulfate by use of an ionic liquid and alcohol blend. Finally provided is an embodiment of a detergent composition which is prepared by use of the polyethoxylated alcohol sulfate composition described herein, in addition to other commonly known ingredients.
