An improved method is provided for reversibly suppressing the viscosity of an aqueous solution containing a hydrophobically-modified thickener by first complexing the hydrophobic moieties on the thickener with a methyl-.beta.-cyclodextrin and then decomplexing the methyl-.beta.-cyclodextrin from the thickener once the aqueous solution containing the thickener is added to the aqueous system which is intended to thicken.
