Abstract

Methods include, providing a liquid composition having a first viscosity that includes a polymeric thickener, a non-aqueous solvent, and water. The non-aqueous solvent and water may form a theta solvent. A solvent with a second viscosity is provided. A portion of the liquid composition is diluted with the solvent forming a use solution with a third predetermined viscosity; where the third predetermined viscosity is greater than the second viscosity.

Claims (50)
