    Characteristics of hydroxypropyl gamma cyclodextrin:

    Hydroxypropyl gamma cyclodextrin dissolves large molecules, such as cholesterol, for cell culture. Hydroxypropyl gamma cyclodextrin is similar to betacyclodextrin, but can dissolve larger molecules.

     

    Application of hydroxypropyl gamma cyclodextrin:

    The water solubility of hydroxypropyl - γ - cyclodextrin was further increased to 80g / 100ml (25 ℃). At the same time, the hydroxypropyl - γ - cyclodextrin was no longer a single pure product, but a mixture of multiple substitutions. It was not easy to form inclusion complex crystal precipitation when it was combined with guest molecules. In general, hydroxypropyl - γ - cyclodextrin had higher water solubility and stronger anti-oxidation ability The ability of crystallization. The solubility of γ - cyclodextrin in water is 23.2g/100ml (25 ℃), and its application is limited in some cases.

    It is suggested that it can be used in high value-added products, such as medicine, health care products, cosmetics and other special materials, or the treatment of hydroxypropyl - β - cyclodextrin.

     

    Packaging of hydroxypropyl gamma cyclodextrin:

    Package specification: 10g / 20g / 50g / 100g / 500g / 1kg / 2kg / 10kg

    Packing form: bottle, carton, cardboard barrel
