LINEAR VISCOELASTIC AQUEOUS LIQUID DETERGENT COMPOSITION, ESPECIALLY FOR AUTOMATIC DISHWASHERS, OF IMPROVED HIGH TEMPERATURE STABILITY ABSTRACT OF THE DISCLOSURE Automatic dishwasher detergent composition is formulated at 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 polycarboxylate 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. Stearic acid or other higher fatty acid mixture or salt further improves physical stability. Use of potassium tripolyphosphate in place of tetrapotassium pyrophosphate reduces formation of crystal growth when the product is subjected to elevated temperatures, such at 100°F.
