Abstract (en)
[origin: EP0345611A2] The physical stability of liquid gel-like compositions based on montmorillonite, attapulgite, hectorite or other inorganic colloid-forming clay or other thixotropic thickener, and small amounts, such as 0.1 to 0.2 weight percent, of calcium, magnesium, aluminium or zinc stearate or other polyvalent metal salt of long chain fatty acid is greatly improved by increasing the alkalinity level to such an extent that when the composition is added to an aqueous wash bath at a concentration of about 10 grams per liter the pH of the wash bath becomes at least 11.2. The aqueous compositions preferably also includes chlorine bleach, and the chlorine-bleach loss with time is also reduced in the high alkalinity formulations. Use as liquid gel-like automatic dishwasher compositions are described.
