Products Description

Hydroxypropyl Beta Cyclodextrin is a cyclodextrin derivative with excellent water solubility. Its molecule features a hollow truncated cone structure, with a hydrophilic outer surface and hydrophobic inner cavity. It can form host-guest inclusion complexes with guest molecules, thereby improving the water solubility of poorly soluble substances.

Applications

◆ 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-term 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.
