Beta-cyclodextrin is a cyclic heptamer composed of seven glucose units joined "head-to-tail" by alpha-1.4 links. It is produced by the action of the enzyme, cyclodextrin glycosyl transferase (CGT),on hydrolyzed starch syrups.And it is white powder and there is a cavity in its molecule which can form inclusion compounds with a range of molecules.The solubility degree of Beta-cyclodextrin in water is 1.85g/100ml @ 25°C, melting point is about 260ºC, internal diameter is 0.7-0.8nm.
This product is white or nearly white amorphous or crystalline powder; odorless, slightly sweet; very soluble in water, soluble in ethanol .
Hydroxypropyl beta cyclodextrin appears as a white powder with good solubility in water and a certain degree of relative hygroscopicity. However, the relative surface activity and hemolytic activity are relatively low. It has no stimulating effect on muscles and is an ideal injection solubilizer and drug excipient.
