Abstract (en)

Automatic dishwasher detergent composition is formulated as 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 which is further modified by the incorporation of a clay flow modifier. Potassium to sodium weight ratios of at least 1/2 minimize amount of undissolved solid particles to further contribute to stability and pourability. Stearic acid or other fatty acid or salt further improve physical stability.
