Hydroxypropyl beta 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.

Hydroxypropyl beta cyclodextrin could increase the stabiliy of molecular nutition and long-term efec,cover up or adjust bad smel and tastes of food nutrfion molecular,jimprove production process and product quality and extend the shelf-life.

Hydroxypropyl beta 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.

Use: solvent, embedding agent, stabilizer, flavor mask, etc.;
