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.
Claims6
A liquid medium, capable per se of stably suspending under high extensional shear rates non-colloidal undissolved particulate material, comprising an aqueous medium in which is present:
- (a) from 0.2 to 70% of non-colloidal undissolved particulate material;
- (b) from 0.5 to 20% of anionic detergent material;
- (c) from 0.5 to 25% of a water-soluble electrolyte;
- and
- (d) from 0.001 to 0.15% of a hectorite clay,
- all percentages being calculated on the final product.
