Product performance:
The introduction of hydroxypropyl breaks the intramolecular cyclic hydrogen bond of beta-cyclodextrin, and overcomes the beta-cyclodextrin while maintaining the cyclodextrin cavity. The main disadvantage of the poor water solubility of dextrin.Hydroxypropyl betacyclodextrin is an ideal solubilizer and excipient.
Scope of application:
Daily chemical grade hydroxypropyl beta cyclodextrin can be used in cosmetic products.
