ABSTRACT OF THE DISCLOSURE DETERGENT COMPOSITIONS A cleaning composition is provided in gel form having a viscosity on a Haake Rotovisco RV-100 Viscometer at 25°C under 5 sec-1 shear of from sbout 1,000 to 20,000 cps and under 21 sec-1 shear of from about 200 to 5,000 cps, a pH range from 11 to 13, and a steady state viscoelastic deformation compliance Je° greater than 0.01. In one embodiment, the composition comprises a polycarboxylate polymeric thickener, especially a cross-linked polyacryllc acid. There preferably is also present either a trivalent metal-containing material, especially an aluminum containing material such as alumina, or a clay such as a hectorite clay. A structuring chelant is a further preferred component which is selected from the salts of carbonate, pyrophosphate and mixtures thereof. When mixed with the polycarboxylate polymer and trivalent metal material, the structuring chelant can form a clear gel. Bleach may be incorporated in encapsulated form. Preferred surfactant is alkyl polyglycoside.
