2-Hydroxypropyl-β-cyclodextrin (HP-β-CD) is a modified form of β-cyclodextrin, which is a cyclic oligosaccharide composed of seven glucose units. Cyclodextrins are often used in various industries, including pharmaceuticals, food, and cosmetics, due to their ability to form inclusion complexes with a wide range of guest molecules.
In the case of 2-Hydroxypropyl-β-cyclodextrin, hydroxypropyl groups are attached to the β-cyclodextrin molecule. This modification improves the water solubility of the cyclodextrin, making it more versatile in applications where increased water solubility is desirable
