Cyclodextrin

Cyclodextrin (CAS 12619-70-4), also supplied under trade names such as Celdex, Ringdex P, and Rhodocap L 20, is a family of cyclic oligosaccharides produced from starch by enzymatic conversion.

In industry, cyclodextrins function as molecular encapsulants, trapping active ingredients within their cavity structure to improve stability, control release, and mask unwanted tastes or odors.

In food manufacturing, cyclodextrins encapsulate flavors, vitamins, and sensitive ingredients to extend shelf life and protect against heat or oxidation during processing stages.

Pharmaceutical formulators use them to improve the solubility and bioavailability of poorly water-soluble active compounds in oral, topical, and injectable dosage forms for patients.

In biotechnology, cyclodextrins serve as excipients in protein stabilization and as tools for cholesterol removal in cell culture media. Flavor houses also apply them for delivery.

They provide controlled-release taste profiles in confectionery, beverages, and functional food products. Cyclodextrin is available in powder and granular forms with alpha, beta, and gamma variants.

Beta-cyclodextrin is the most commercially prevalent type and is available in food-grade and pharmaceutical-grade specifications. It meets various global quality standards for industrial use.

Hydroxypropyl beta-cyclodextrin, a chemically modified derivative, is also widely stocked for pharmaceutical and biotech applications where enhanced aqueous solubility is required for the final product.
