Description and Uses

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.
