摘要

PURPOSE: A composition for a hydrophobic thickener system of reduced viscosity, a method for preparing a hydrophobic thickener system of reduced viscosity, and a method for increasing the viscosity of a polymer-containing aqueous system are provided, to reduce the amount of expensive cyclodextrin required for inhibiting the viscosity of a hydrophobicity-modified associative thickener by improving the efficiency of viscosity inhibition. CONSTITUTION: The composition a hydrophobic thickener system of reduced viscosity comprises a cyclodextrin-containing compound having a hydrophobic cavity of a predetermined size; and a hydrophobicity-modified associative thickener containing at least one terminal phobe capable of forming a complex with the hydrophobic cavity, wherein at least some part of the cyclodextrin-containing compound forms a complex with the hydrophobicity-modified associative thickener in the way that at least some part of at least one phobe fills at least some part of the hydrophobic cavity.
