Abstract
A thickened aqueous bleaching cleanser has a viscosity of at least 100 centipoise, provides a cleaning-effective residence time on non-horizontal surfaces, and maintains viscosity and bleach stability over a typical shelf life. In one embodiment the cleanser comprises a source of a halogen bleach, a copolymer thickener including a hydrophobic comonomer and a hydrophilic comonomer, and a mixed surfactant system including an uncharged surfactant and an anionic surfactant.
