CM-β-CD

Carboxymethyl-β-cyclodextrin has low solubility in low pH solution, but in the neutral solution and alkaline solution (pH> 4), because of the dissociation of the carboxyl group, it can be dissolved in any concentration, and its structure is loose, the self motion is significantly improved. It has good solubility in the environment of pH 6-7 value in human intestinal tract.
