ABSTRACT:
A cleaning formulation comprising a cleaning agent, a particulate clay material and an aqueous carrier. The formulation has a pH less than about 4.0 and is characterized by at least a 90% reduction in viscosity at 25° C. at a shear rate of up to about 0.10 s−1. The cleaning formulation is thixotropic and has a highly desirable combination of acid stability, temperature stability, electrolyte stability and ultraviolet radiation stability.
