Abstract
Stable, thickened, aqueous bleaching and cleaning compositions contain hypochlorite and a thickening mixture of high molecular weight polycarboxylate polymer and amine oxide detergent surfactant. Optionally, the compositions can also contain fatty acid, as soap, and/or synthetic anionic bleach stable detergent surfactant. The viscosity is between about 150 and 3,000 centipoises to permit easy dispensing, but still provide a coating action. The compositions are especially good for use in cleaning toilet bowls, bathroom tiles, and shower walls.
