Description

ζ-Cyclodextrin is a specialized, large-ring cyclodextrin derivative with a unique cavity structure. This molecular characteristic makes it a highly effective host molecule for forming inclusion complexes, enhancing the solubility, stability, and bioavailability of various guest compounds. It is essential for industries requiring advanced molecular encapsulation and controlled release systems. Key sectors that utilize this technology include pharmaceuticals, agrochemicals, food science, and cosmetics.

Application

• Pharmaceutical Formulations: Used to improve the aqueous solubility, dissolution rate, and chemical stability of poorly soluble active pharmaceutical ingredients (APIs).
• Agrochemical Delivery Systems: Enhances the stability and efficacy of pesticides and herbicides by protecting them from degradation and controlling their release.
• Food & Flavor Industry: Acts as a flavor carrier and stabilizer, masking off-tastes and protecting sensitive compounds from oxidation, light, or heat.
• Cosmetics & Personal Care: Employed to stabilize fragrances, vitamins, and other active ingredients in creams, lotions, and serums.
• Chemical Synthesis & Catalysis: Serves as a green, supramolecular catalyst or reaction medium to enhance selectivity and yield in organic reactions.
• Environmental Remediation: Applied in formulations for the sequestration and removal of organic pollutants from water and soil.
• Diagnostic & Analytical Reagents: Used as a chiral selector in capillary electrophoresis and HPLC for the separation of enantiomers.

Quality Control

Our ζ-Cyclodextrin is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting these results are provided and can be tailored to meet specific customer or regulatory requirements, including those for pharmaceutical (GMP) or food-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance and flow characteristics.
