Gamma cyclodextrin

Gamma cyclodextrin (CAS 17465-86-0), also identified as γ-CD, Ringdex C, and approved food additive E458, is a cyclic oligosaccharide derived from starch. It features a toroidal molecular structure that enables it to encapsulate guest molecules within its cavity.

This encapsulation function drives its commercial value across pharmaceuticals, food, and personal care. It is primarily used for improving the stability, solubility, and controlled release of various active ingredients in industrial applications.

In pharmaceutical formulations, γ-CD encapsulates poorly soluble active compounds to enhance bioavailability. It is also frequently utilized to mask undesirable tastes or odors in oral dosage forms to improve patient compliance.

Food manufacturers use it under E458 approval to stabilize volatile flavor compounds and extend the shelf life of sensitive ingredients. It can also be used to reduce fat perception in various reduced-calorie products.

In personal care, it encapsulates fragrance molecules and actives in skin and hair care formulations. This process enables controlled release and improved product longevity for high-end cosmetic applications.

Its chelating capacity also allows it to sequester metal ions in formulations where oxidative stability is a concern. Gamma cyclodextrin is supplied as a white crystalline powder for easy handling and processing.

It is available in food-grade specification compliant with E458 regulatory requirements. We also offer pharmaceutical-grade material meeting USP and Ph.Eur. standards for regulated medical applications.

Technical-grade material is also offered for industrial encapsulation applications where high purity is required. Our product ensures consistent performance across all manufacturing and formulation sectors.
