Description

β-Cyclodextrin Hydrate is a cyclic oligosaccharide derived from starch, consisting of seven glucose units linked by α-(1,4) glycosidic bonds. This unique molecular structure creates a hydrophobic internal cavity and a hydrophilic external surface, enabling it to form inclusion complexes with a wide variety of guest molecules. It is a critical functional excipient and additive for enhancing solubility, stability, and bioavailability in pharmaceutical, food, and cosmetic formulations. Industries requiring advanced encapsulation and delivery solutions, such as pharmaceuticals, nutraceuticals, and specialty chemicals, rely on its consistent performance.

Application

• Pharmaceutical Formulations: Used as a complexing agent to improve the aqueous solubility, stability, and bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Food & Flavor Industry: Acts as a flavor carrier and stabilizer, protecting volatile aromas and masking undesirable tastes or odors in food products and beverages.
• Cosmetics & Personal Care: Employed to stabilize fragrances, vitamins, and other active ingredients in creams, lotions, and serums, while also reducing skin irritation.
• Chemical Separation & Analysis: Utilized in chiral chromatography as a stationary phase or mobile phase additive for the separation of enantiomers.
• Agrochemicals: Enhances the stability and controlled release of pesticides and herbicides, improving their efficacy and environmental profile.
• Nutraceuticals & Supplements: Improves the delivery and shelf-life of sensitive bioactive compounds like vitamins, fatty acids, and plant extracts.

Quality Control

Our β-Cyclodextrin Hydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets relevant specifications for pharmaceutical (USP/Ph. Eur.), food (FCC), or technical grades. Key parameters such as assay, water content, residue on ignition, and microbial limits are rigorously controlled. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

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 properties.
