Abstract
A stable liquid automatic dishwashing compositions as well as a process for its preparation is disclosed. The composition is an aqueous thixotropic fluid possessing a yield point. The composition may include swellable clays, synthetic polymers, a specified amount of multivalent cations, builder salts, an alkaline source, a hypochlorite source, nonionic or anionic surfactants, and defoamers. The system containing clay, polymer, and ions thickens the composition to provide structure to suspend finely divided solid components, while maintaining good salt tolerance and stability against hypochlorite.
