1. A method comprising:
- a. providing a liquid composition having a first viscosity comprising;
i. a polymeric thickener;
ii. a non-aqueous solvent; and
iii. water;
wherein the non-aqueous solvent and water form a theta solvent;
b. providing a solvent with a second viscosity; and
c. diluting a portion of the liquid composition with the solvent forming a use solution with a third predetermined viscosity, wherein the third predetermined viscosity is greater than the second viscosity.

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.
