Abstract
An aqueous cleaning composition is provided in a gel form having a viscosity on a Haake Rotovisco RV-100 Viscometer at 25.degree. C. under 5 sec.sup.-1 shear of from about 1,000 to 20,000 cps and under 21 sec.sup.-1 shear of from about 200 to 5,000 cps, a pH range from 11 to 13, and a steady state viscoelastic deformation compliance J.sub.e .degree. greater than 0.01, and wherein the light transmittance through a sample 2 cm thick is at least 10%. The composition will incorporate a polycarboxylic polymeric thickener, especially a cross-linked polyacrylic acid. Also present will be a structurant which can either be up to 2% alumina or up to 0.05% hectorite clay. Also present in the composition will be from 0.01 to 20% of an alkyl polyglycoside which ensures improved cleaning and clarity.
