  • Stable liquid detergent suspensions
    Patent number: 4530775
    Abstract: Liquid media, capable of stably suspensing undissolved particulate material, comprise, in an aqueous medium, an anionic detergent, a non condensed phosphate electrolyte and a fatty acid monoalkylolamide. Such media, and the suspensions of undissolved particulate material therein, have a significantly improved shear stability. The media are particularly useful to suspend particulate abrasive material to yield liquid abrasive cleaning compositions.
