International ClassesC11D 003/37C10D 003/395 AbstractA cleaning composition is provided comprising a cross-linked polycarboxylic polymer and a clay, the combination interacting to provide a gel with certain rheological properties. These properties include a viscosity on a Haake Rotovisco RV-100 Viscometer at 25° C. under 5 sec-1 shear of from 1,000 to 20,000 cps and under 21 sec-1 shear of from about 200 to 5,000 cps, with a steady state viscoelastic deformation compliance Je ° greater than 0.01. Preferably, the clay is a hectorite present in an amount from about 0.005 to about 0.1% by weight. Clear gel compositions are herewith obtainable.Other References
