Hydroxypropyl gamma cyclodextrin ( HP-γ-CD ) CAS NO.: 128446-34-4 Standard: In-house Standard Appearance: White powder,sweet,insipid and innocuous Shelf life: 36 Months Application: Pharmaceuticals, Food,Cosmetics Molecular formula : C48H80-nO40.(C3H7O)n Molecular weight: 1297.2+n.(58.1) Hydroxypropyl gamma cyclodextrin is an important gamma cyclodextrin derivatives. Especially for the inclusion of larger molecules,it can be used as solubilier,embedding medium,stabilizer and odor absorber in various fields. In Pharmaceuticals Hydroxypropyl gamma cyclodextrin  is a solution to insoluble or low solubility  drugs(including plant extracts).Through molecular encapsulation,it could increase the drug solubility and control the release rate of the drug,increase the drug's bioavailability and reduce the toxic side-effets. In Food Hydroxypropyl gamma cyclodextrin could increase the stability of molecular nutrition and long-time effect,cover up or adjust bad smell and tastes of food nutrition molecular,improve production process and product quality and extend the shelf-life. In Cosmetics Hydroxypropyl gamma cyclodextrin used as stabilizer,emulsifier and odor absorber.It could reduce organic molecules stimulation to skin mucosal and enhance the stability of the effective components.Prevent volatile ,oxidation of nutrient composition ,increase the solubility of insoluble flavours and fragrances and keep the fragrance slow releasing and lasting.
