Abstract

Aqueous, thickened liquid or gel cleaning compositions displaying enhanced chemical and physical stability are provided. The compositions comprise a chlorine bleach ingredient, cross-linked polycarboxylate polymer, phytic acid, a theology stabilizing agent, and a buffering agent to maintain the pH of the composition above about 10. The phytic acid component is, preferably, substantially free of hypochlorite-reactive species. Preferred automatic dishwashing detergent compositions containing builder and optional surfactant and metalate, and displaying shear thinning behavior, are also disclosed.
