Hydroxypropyl-Beta-Cyclodextrin(β -cyclodextrin, 2-hydroxypropyl ether) is a partially substituted poly(hydroxypropyl) ether of BetaCyclodextrin. It is mainly used in food, medicine and cosmetincs, in medicine, can increase the solubility of the medicine, add up the good effect and reduce the number which is taken, meanwhile, it can control the reactive speed, reduce the side effect of the medicine.
