Product Introduction
Gamma cyclodextrin has 8 glucose subunits and has a larger cavity than betacyclodextrin, so the cavity can include a wider range of guest molecules, better water solubility, and a broader application prospect than betacyclodextrin. However, due to the small production scale, the price is higher, which limits the popularization of application.

Application
In the field of Pharmaceutical：
It is mainly used to increase the solubility and stability of drugs. Cyclodextrin inclusion compounds with hydrophobic molecules are able to penetrate human tissues and can be used to release bioactive compounds under specific conditions. Enhance the mucosal permeability of the drug.
In the field of cosmetics, cyclodextrins are mainly used as a transport medium. At present, the transmission media of cosmetics can be divided into four categories: emulsion system, porous system, particle system and molecular system. Among them, cyclodextrin is a molecular transport medium. In recent years, cyclodextrin as a cosmetic formula has been widely used in skin care creams, lotions, shampoos, toothpastes, perfumes and other products to improve the effectiveness of cosmetics in whitening, anti-aging, moisturizing, acne, sterilization and other aspects.
