Abstract
A process for preparing viscoelastic, thixotropic, liquid, polymer-containing detergent compositions which exhibit increased density, enhanced aesthetics and improved rheological efficiency of the polymer is provided. The polymer thixotropic thickening agent is simultaneously added and mixed as a slurry to a premix under moderate to high shear rate to neutralize and disperse the polymer. The product is deaerated to increase density and enhance aesthetics by continued mixing under low to moderate shear rate of the slurry/premix composition. Sequential addition and mixing to the slurry/premix of organic solvent, oil, suds suppressors and solid material can aid in the deaeration step.
