ABSTRACT:
An aqueous solution of an alkali metal neutralized polyacrylic acid and an alkali metal detergent builder salt and/or an alkali metal silicate is used as a base stock polymeric solution for the fomulation of an automatic dishwasher detergent composition which is a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance. Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener. Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability. Control of incorporated air bubbles functions to provide the product with a bulk density of about 1.35 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improved physical stability.
