Hydrxypropyl- gamma-cyclodextrin Typical Properties
Hydroxypropyl gamma cyclodextrin's water solubility increase to 80g/100ml (25ºC) 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.
