Usage of Hydroxypropyl gamma cyclodextrin

Hydroxypropyl gamma cyclodextrin's water solubility increase to 80g/100ml (25 C) furtherly , and hydroxypropyl gamma cyclodextrin is no longer a single pure compound but a coexistence of multiple substituted compounds, when including with guest molecules is not easy to generate crystallization. Overall, hydroxypropyl- gamma cyclodextrin has a higher solubility in water and  stronger  anti crystallization ability.
