The physical stability and rheological properties variations of liquid gel-like compositions based on montmorillonite, attapulgite, hectorite or other inorganic colloid-forming clay or other thixotropic thickener are greatly improved by incorporating in the composition small amounts such as about 1.0-2.0 weight percent of potassium polyphosphates and small amounts such as 0.2 or 0.4 weight percent of calcium, magnesium, aluminium or zinc stearate or other polyvalent metal sail of a long chain fatty acid. The thixotropic properties can be retained or improved using smaller levels, such as 0.20 to 0.5%, of the clay thixotropic thickener than in the absence of the potassium polyphosphate physical stabilizer. Use as liquid gel-like automatic dishwasher compositions are described. |
