Patent ID: 7737103

Claim:
A multicomponent system, the system comprising: a) a first alkaline aqueous liquid having a pH of up to 14 and containing at least one hydrophobically modified polymer in an amount of 0.1 to 2.0% by weight; and b) a second alkaline aqueous liquid having a pH of up to 14 and containing at least one hydrophobically modified polymer in an amount of 0.1 to 2.0% by weight and at least one surfactant wherein the hydrophobically modified polymer has a molecular weight of 10 to 1,000 kDa and a degree of modification of 1 to 10% , and wherein the viscosity of a mixture of the first and second alkaline aqueous liquids at a shear rate of 0.1 s −1 is at least about twice as high as the viscosity of at least one of the first or second alkaline aqueous liquids.
