Usage

1). In pharmaceutical field, gamma-cyclodextrin pharmaceutical grade and medicine could produce inclusion compound, which could: A. make unstable medicine stable; B. make deliquescing, sticky and liquid medicine more powder-like; C. make insoluble or hard-soluble medicine soluble.

2). In pesticide field, gamma-cyclodextrin pharmaceutical grade and medicine could produce inclusion compound

to make some pesticides store and increase insecticidal efficacy.

3). In food field,gamma-cyclodextrin pharmaceutical grade could: A. cover and remove peculiar smell; B. improve

and enhance food organization structure; C. relieve and remove bitter and astringent;

D. anti-oxidation; E. keep and improve relish.

4). In daily chemical field, gamma-cyclodextrin pharmaceutical grade could function as emulgator and quality improver in cosmetics production. It could also be applied in tooth paste and tooth powder as deodorant and preservative.

5). In environment-protection field, gamma-cyclodextrin pharmaceutical grade could be applied as treatment of waste water with oil. Alpha-cyclodextrin water solution could be used to clean oil groove and recycle it to get fuel oil.

6). In chemical field, fluorescence intensity of fluorchrome is enlarged remarkably with gamma-cyclodextrin pharmaceutical grade, so it could be used to analyze protein and amino acid. It could also be used to separate long-chain organic compounds, raceme etc. Besides, absorbent made from gamma-cyclodextrin pharmaceutical grade could be used as adsorption of chromatographic analysis.
