Hydroxypropyl-beta-cyclodextrin HPCD CAS No.:128446-35-5 /94035-02-6 Introduction:
H&Z® Hydroxypropyl-beta-cyclodextrin: Hydroxypropyl beta-cyclodextrin are purified polydisperse products resulting from the controlled reaction of propylene oxide and native beta-cyclodextrin. Hydroxypropyl beta-cyclodextrin is itself very soluble in water (greater than 500 mg/ml at room temperature compared to 18 mg/ml for beta-cyclodextrin), and is used for molecular encapsulation of a variety of sparingly water compounds to enhance the aqueous solubility of the encapsulated compound.
