Feature:

Hydroxypropyl beta-cyclodextrinare purified polydisperse products resulting from the controlled reaction ofpropylene oxide and native beta-cyclodextrin. Hydroxypropyl beta-cyclodextrin isitself very soluble in water (greater than 500 mg/ml at room temperature comparedto 18 mg/ml for beta-cyclodextrin), and is used for molecular encapsulation of a varietyof sparingly water compounds to enhance the aqueous solubility of theencapsulated compound.
