    • Company Introduction

      Xi’an DELI  Biochemical  Industry Co., Ltd. was established in  August 1999. The company is located  in Daixin  Industrial Park  at  the  foot  of  Lishan  Mountain.  It covers  an area of about 14000  square  meters and is  a  modern  pharmaceutical  excipients manufacturer of integrating research  and  development,  production  and  sales.  The  company  independently  developed Hydroxypropyl  Beta  Cyclodextrin,  Betadex  Sulfobutyl  Ether  Sodium  and  other  kinds  of cyclodextrin  excipients.  We  are  the  first  enterprise  to  be  approved by the State Food  and Drug  Administration  who  can  produce  the  injection   grade Hydroxypropyl  Beta Cyclodextrin in  China. The company  quality management  system has  passed   IS09001:2015  certification. The company  now has  a  high  standard production workshop of 1000  square meters, inspection equipment  includes:  Waters  HPLC  System,  Agilent  gas  chromatograph,  Acidity  meter, Infrared  spectromete rAB SCIEX Capillary electrophoresis system and so on, our company can meet the testing requirements of all projects  in  each production link. The products are stable and exported to  Asia, Africa, Europe and America. Our company also has been rated as a high and new technology enterprise for many years.



    Hydroxypropyl Betadex is the hydroxyalkylation derivative of Beta Cyclodextrin. Hydroxypropyl Betadex is non-toxic and has no side-effect. Due to its unique structure, it can improve the solubility of drugs, and making the insoluble and the indissolvable drugs dissolved in water. Consequently, it can effectively improve the bioavailability of drugs, and significantly increase the quality of medicine and dosage form. And it is widely used in the development and manufacture of new drugs.

    There has been intensive and deep research on the quality, manufacturing process, stability, pharmacology, toxicology, teratogenesis, mutagenesis, carcinogenicity, hemolysis, irritation and other aspects in world, and has obtained accurate evaluation of its safety. It is safe to conclude that derivative of cyclodextrin is the pharmaceutic excipients received the most intensive research, having the most comprehensive information, and having the highest value in medicine excipients.

    Betadex Sulfobutyl Ether Sodium is a sodium salt produced when betacyclodextrin is alkylated by 1,4-butanesulfonic acid lactone under alkaline conditions. It is an anion, highly water-soluble betacyclodextrin derivative. Betadex Sulfobutyl Ether Sodium is can be well combined with the drug molecules to form non-covalent complex, thereby enhancing the stability, water solubility, and safety of the drug, reducing its renal toxicity, easing drug hemolysis, controlling drug release rate, covering bad smell, etc. Compared with betacyclodextrin, sulfobutyl betacyclodextrin sodium has a higher water solubility, smaller hemolytic effect, and lower renal toxicity, which make it a new pharmaceutical excipient with very broad application prospects.
