Cyclodextrin

Product Overview

Description

Cyclodextrins are composed of 5 or more α-D-glucopyranoside units linked 1->4, as in amylose (a fragment of starch). The 5-membered macrocycle is not natural. Recently, the largest well-characterized cyclodextrin contains 32 1,4-anhydroglucopyranoside units, while as a poorly characterized mixture, at least 150-membered cyclic oligosaccharides are also known. Typical cyclodextrins contain a number of glucose monomers ranging from six to eight units in a ring, creating a cone shape:

 * α -cyclodextrin: 6-membered sugar ring molecule

 * β -cyclodextrin: 7-membered sugar ring molecule

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.

1.Hydroxypropyl Beta Cyclodextrin is used as stabilizers, emulsifiers, deodorant in cosmetic.

2.Hydroxypropyl Beta Cyclodextrin can decrease the stimulating effect on the skin produced by organic composition of cosmetic.

3.Hydroxypropyl Beta Cyclodextrin can prevent nutrient ingredient evaporating and oxidating, increase water-soluble of spices and essence, keep fragrance's sustained and release lasting.
