solubility	1 M NH4OH: 50 mg/mL

Application:	β-Cyclodextrin is used as a complexing agent in drug delivery because it forms an inclusion complex with a drug molecule. The complex of cyclodextrin increases the aqueous solubility, dissolution rate and bioavailability of poorly water-soluble drugs, which is useful for the delivery of the medical agent to a biological system.
General description:	β-Cyclodextrin is a cyclic oligosaccharide consisting of seven glucose subunits joined by α-(1,4) glycosidic bonds forming a truncated conical structure. It is widely used in food, pharmaceutical, cosmetics, and chemicals industries.
Packaging:	25, 100, 500 g in poly bottle
