Thickener composition and method for thickening aqueous systems

摘要

The thickening action of associative thickeners is thought to involve hydrophobic interactions between hydrophobic moieties in the thickener molecules or between the hydrophobic moieties and other hydrophobic surfaces. Polyether associative thickeners are non-ionic thickeners and their thickening efficiency is independent of pH. It is desirable that the thickener itself is supplied as a readily pourable aqueous liquid(in order to drain from its container),and without need to dilute in water or organic co-solvent,which limits formulation options.
