Hydroxypropyl-Beta-Cyclodextrin

Hydroxypropyl-Beta-Cyclodextrin (HPBCD), identified by CAS 128446-35-5, is a chemically modified cyclic oligosaccharide derived from Beta-Cyclodextrin. It appears as an off-white powder with exceptional water solubility compared to its parent compound.

HPBCD is widely utilized in industrial chemistry as a molecular "host" to form inclusion complexes. By encapsulating hydrophobic molecules within its cavity, it dramatically improves their solubility, stability, and volatility control. Our HPBCD (Technical Grade) offers a high purity of 92.4% and a controlled pH of 6.23, making it an essential additive for advanced coatings, agricultural chemicals, and high-performance polymer systems.
