A method is provided for improving thickeners used in aqueous system. The improvement is directed to the elimination of organic cosolvents which are conventionally added to aqueous solutions of certain hydrophobic thickeners. This method involves the reversible complexation of cyclodextrin compounds with hydrophobia moieties on the thickener molecule to suppress the viscosity of the aqueous solution containing the thickener so that such the solution can be easily handled. This is followed by decomplexing the cyclodextrin from the thickener to permit the thickener to perform its intended function.
