 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 product but the coexistence of multiple substituted compounds, with guest molecules when wrapping is not easy to generate inclusion crystallization. Overall, hydroxypropyl- gamma cyclodextrin has a higher solubility in water and  stronger  anti crystallization ability.
