Hydrxypropyl- gamma-cyclodextrin Typical Properties

Hydroxypropyl gamma cyclodextrin’s water solubility increase to 80g/100ml (25℃) furtherly , and hydropropyl 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.
