摘要：
A stable thixotropic liquid automatic dishwashing composition is disclosed. The composition may include swellable clays, synthetic water dispersible sulfonated polymers, optionally multivalent cations, builder salts, an alkaline source, a hypochlorite source, nonionic or anionic surfactants, and defoamers. The system, containing clay and sulfonated polymer, and optionally multivalent metal ions, thickens the composition to provide structure to aid in suspending finely divided solid components, while maintaining good salt tolerance, stability against hypochlorite and acceptable cup retention with shear-thinning rheological behavior.
