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.

Where is Gamma cyclodextrin used?

• Pharmaceuticals: encapsulates poorly soluble active compounds to enhance bioavailability
• Oral dosage forms: masks undesirable tastes or odors to improve patient compliance
• Food: under E458 approval, stabilizes volatile flavor compounds and extends shelf life of sensitive ingredients
• Reduced-calorie products: reduces fat perception
• Personal care: encapsulates fragrance molecules and actives in skin and hair care formulations
• Its chelating capacity allows it to sequester metal ions where oxidative stability is a concern.

Commercial specifications

• Food-grade specification compliant with E458
• Pharmaceutical-grade material meeting USP and Ph. Eur. standards
• Technical-grade material for industrial encapsulation where high purity is required
