The object of the present invention is to provide a liquid composition for increasing viscosity when the viscosity of the thickening agent is lowered, and when it is diluted, the viscosity of the thickening agent is restored.In the liquid composition for the thickening containing the thickening agent, the amount of the highly branched cyclic dextrin and \/ or the addition amount of the starch decomposed product of DE1 to 15 is set to be greater than the threshold concentration which produces the effect of decreasing the viscosity of the thickening agent, and the highly branched cyclic dextrin and Also, the concentration of the starch decomposed product of DE1 to 15 is set to be less than the threshold concentration after dilution by the diluent material containing water, and the viscosity of the thickening agent is in the state where the viscosity is lowered, and the viscosity of the thickening agent is inherent after dilutionRecoverable.本発明の目的は、増粘剤の粘性を低下させた状態で存在させ、且つ希釈すると増粘剤が本来有する粘性を回復できる増粘用液体組成物を提供することである。 増粘剤を含む増粘用液体組成物において、高度分岐環状デキストリン及び/又DE1~15のデンプン分解物の添加量を増粘剤の粘性を低下させる効果を奏する閾値濃度以上に設定し、且つ高度分岐環状デキストリン及び/又DE1~15のデンプン分解物の濃度が、水を含む希釈原料による希釈後には当該閾値濃度未満になるように設定することにより、増粘剤を粘性が低下した状態で存在させつつ、希釈後には増粘剤が本来有する粘性を回復できる。
