β-Cyclodextrin CAS#7585-39-9
Cyclodextrins refer to a family of compounds consisting of sugar molecules bound together in ring (cyclic oligosaccharides). It is produced from starch through enzymatic conversion. Beta-cyclodextrin is the 7-membered sugar ring molecular form of cyclodextrin. Cyclodextrin has various applications. In the pharmaceutical industry, it can be used as complexing agents for increasing the solubility of poorly soluble drug as well as increasing their bioavailability and stability. It can also alleviate the gastrointestinal drug irritation, and prevent drug-drug and drug-excipient interactions. It can also be used in food, pharmaceutical, drug delivery, and chemical industries, as well as agriculture and environmental engineering.

Product Application of β-Cyclodextrin CAS#7585-39-9
Use to solubilize non-polar compounds such as fatty acids, lipids and cholesterol. Reported useful for the selective precipitation of enantiomeric, positional or structural isomersβ-Cyclodextrin is used with dansyl chloride to form water-soluble complexes for fluorescent labeling of proteins. It is an active ingredient of household odor eliminator. It is also used in personal care products like toothpastes, skin creams and dusting powders. It finds applications in the cosmetic industry for products like detergents and perfumes for the controlled release of fragrances. Further, it is used to produce HPLC columns allowing chiral enantiomers separation. In addition to this, it is used to decrease the level of cholesterol in milk fat.
