Hydroxypropyl Beta Cyclodextrin CAS NO.128446-35-5

Hydroxypropyl beta cyclodextrin is an important cyclodextrin derivatives. Hydroxypropyl beta-cyclodextrin are purified polydisperse products resulting from the controlled reaction of propylene oxide and native beta-cyclodextrin. Hydroxypropyl beta-cyclodextrin is itself very soluble in water (greater than 500 mg/ml at room temperature compared to 18 mg/ml for beta-cyclodextrin), and is used for molecular encapsulation of a variety of sparingly water compounds to enhance the aqueous solubility of the encapsulated compound. It can be used as solubilier, embedding medium, stabilizer and odor absorber in various fields.

Products Applications

In Food:

Hydroxypropyl beta cyclodextrin could increase the molecular stability of 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 Daily Chemical Field

Hydroxypropyl beta cyclodextrin is 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.

In the field of medicine

1.Hydroxypropyl Beta Cyclodextrin is an ideal injection solubilizer and pharmaceutical excipients because of lower surface activity and hemolytic activity, no muscle irritation.

2.Hydroxypropyl Beta Cyclodextrin can increase solubility and bioavailability of drugs, increase pharmaceutical efficacy and reduce the dose of drugs.

3.Hydroxypropyl Beta Cyclodextrin can control release rate of drugs, decrease side effects of drugs, and enhance the stability of drugs.

4.Hydroxypropyl Beta Cyclodextrin is used in oral drugs, injections, drug delivery systems, transdermal drug delivery systems, vector of lipophilic drug targeting, protective agents and stabilizers of protein.

In the field of food and spices

it can improve the stability and long-term effectiveness of nutritional molecules, mask or correct the bad odors and tastes of food nutrition molecules, and can improve the production process and product quality. The product has good solubility in water, substitution degree 4 and above can be miscible with water in any ratio, and can also be dissolved in 50% ethanol and methanol.
