Applications:
Hydroxypropyl-β-cyclodextrin (HP-β-CD) is one of the most widely used cyclodextrin derivatives in current scientific researches and industry applications. It mainly used in food, pharmaceutical and cosmetics industries.
   1. In pharmaceuticals industry, HP-β-CD can increase solubility and bioavailability of insoluble drugs, so that the efficacy of drugs can last longer with less ingestion of drugs. It can adjust and control drugs release ratio, decrease side effects of drugs, and enhance stability of drugs. |
