Summary
Properties
Product Detail

It has the same application capabilities with β-cyclodextrin, while α-cyclodextrin has a better water solubility, the solubility of α-cyclodextrin in water is 12.7g/100ml at room temperature of25 ℃, while the water solubility of β-cyclodextrin is only1.88g/100ml. Therefore α-cyclodextrin has a greater range of applications.
