Description

Cyclodextrin is a family of cyclic oligosaccharides derived from starch, known for their unique molecular structure that forms a hydrophobic internal cavity. This property makes them invaluable as molecular encapsulation agents, enhancing the solubility, stability, and bioavailability of a wide range of guest molecules. Key industries that rely on cyclodextrins include pharmaceuticals, food and beverage, cosmetics, and agrochemicals for applications in drug delivery, flavor protection, and controlled release systems.

Application

• Pharmaceutical Formulations: Used to improve the solubility, stability, and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs) in oral, topical, and injectable drugs.
• Food & Flavor Industry: Acts as a flavor carrier and stabilizer, protecting sensitive compounds from oxidation, light, and heat, and for controlling the release of flavors and nutrients.
• Cosmetics & Personal Care: Employed to stabilize fragrances, vitamins, and other active ingredients, reduce odors, and enhance skin delivery in creams and lotions.
• Agrochemicals: Used in pesticide and herbicide formulations to enhance stability, reduce volatility, and improve the controlled release of active ingredients.
• Chemical Separation & Analysis: Serves as a chiral selector in chromatography (e.g., HPLC, GC) for the separation of enantiomers and isomers.
• Environmental Remediation: Applied to form inclusion complexes with pollutants, aiding in the extraction and removal of organic contaminants from soil and water.

Quality Control

Our Cyclodextrin is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for purity, identity, and performance. We provide comprehensive Certificates of Analysis (COA) that detail key parameters such as assay, moisture content, residue on ignition, and microbial limits. Our quality standards align with major pharmacopoeial guidelines (USP/EP) and food-grade specifications (FCC) where applicable, ensuring reliable and consistent material for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product should be stored in a cool, dry place at a controlled room temperature (15-25°C). For long-term storage, consider using a desiccant in the storage environment to maintain product integrity.
