Methylpredicillin dextrin at room temperature water solubility is high, generally greater than 75%. Widely used in animal health products (pet medicine) and cosmetics and other fields, methylperethane dextrin than other cyclodextrin package and ability stronger. Especially its ability to contain oil-soluble molecules is particularly strong. (RM-β-CD), which is a high degree of substitution methylation-β-cyclodextrin (RM-β-CDH), that is, the average molecular degree of substitution MS = 8-14, and low degree of substitution methylation-β-cyclodextrin (RM-β-CDL) average molecular degree of substitution MS = 4-6. Both are well water-soluble and increase as the temperature increases. Highly substituted methylpredicillin is better than the low-substituted methylpredcyclodextrin and is soluble in ethanol and chloroform. Solubility at room temperature greater than 100g / 100ml. Lowly substituted methylpredicillin can only be dissolved in water and ethanol, insoluble in chloroform. The water solubility at room temperature is about 50g / 100ml, both of the guest material envelope capacity is greater than the parent times its cyclodextrin, the viscosity reduction effect of thickeners, high-substituted methylpredcyclic dextrin than the low-substituted Polycyclohexane dextrin is superior. Methylpentate cyclodextrin is very good, is the object of the ideal solvent and stabilizer.
