Solubility of α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin in water under different temperatures including 25, 45, and 60 °C (Poulson et al. 2022). Cyclodextrins can be dissolved in water. α-cyclodextrin can be dissolved in water by 12.8, 29.0, and 66.2 mg/100 mL at 25, 45, and 60 °C, respectively. β-cyclodextrin can be dissolved in water by 1.8, 4.5, and 9.1 mg/100 mL at 25, 45, and 60 °C, respectively. γ-cyclodextrin can be dissolved in water by 25.6, 58.5, and 129.2 mg/100 mL at 25, 45, and 60 °C, respectively. γ-cyclodextrin has a higher water solubility among the three cyclodextrin types. α-CD refers to α-cyclodextrin, β-CD refers to β-cyclodextrin, and γ-CD refers to γ-cyclodextrin
