Hydroxypropyl beta cyclodextrin is an important cyclodextrin derivatives.it can be used as solubilier,embedding medium,stabilizer and odor absorber in various fields.

In Pharmaceuticals

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.

In Food

Hydroxypropyl beta 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 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.
