Description

γ-Cyclodextrin Hydrate is a cyclic oligosaccharide composed of eight glucose units, forming a toroidal structure with a hydrophilic exterior and a hydrophobic internal cavity. This unique molecular architecture enables it to form inclusion complexes with a wide variety of guest molecules, enhancing their solubility, stability, and bioavailability. It is an essential functional ingredient for industries requiring advanced molecular encapsulation, including pharmaceuticals, nutraceuticals, food technology, and cosmetics.

Application

• Pharmaceutical Formulations: Used to improve the aqueous solubility, dissolution rate, and chemical stability of poorly soluble active pharmaceutical ingredients (APIs).
• Food & Beverage Industry: Acts as a flavor carrier, stabilizer, and masking agent for bitter tastes or unwanted odors in functional foods and supplements.
• Cosmetics & Personal Care: Enhances the stability and skin delivery of active compounds in creams, lotions, and serums; can also be used for fragrance encapsulation.
• Analytical Chemistry & Separation Science: Employed as a chiral selector in capillary electrophoresis and HPLC columns for enantiomeric separation.
• Agrochemicals: Used to formulate pesticides and herbicides, improving their solubility, reducing volatility, and mitigating environmental impact.
• Catalysis & Material Science: Serves as a molecular scaffold or nano-reactor in green chemistry applications and the synthesis of advanced materials.
