Abstract
The invention pertains to liquid media, in which particulate materials can be stably suspended, e.g. liquid abrasive cleaning compositions. These products can suffer from a shear-stability problem, and according to the invention this problem can be overcome by the inclusion of a low level, e.g. 0.001-0.2% of a hectorite clay.
