A thixotropic aqueous detergent for use in household automatic dishwashers comprises alkali metal tripolyphosphate, dispersed clay thickener, a chlorine bleach compound and a water-soluble carboxylic acid or salt thereof. A particularly preferred polymer is sodium polyacrylate having a molecular weight in the range of about 1000 to about 500,000. Low molecular weight polymers e.g. 1000 to 50,000 provide less filming on glass. |
