Description

β-Cyclodextrin is a cyclic oligosaccharide composed of seven α-(1,4)-linked D-glucopyranose units, forming a toroidal molecular structure with a hydrophobic internal cavity and a hydrophilic external surface. This unique architecture enables it to form inclusion complexes with a wide variety of guest molecules, enhancing their solubility, stability, and bioavailability. It is an essential functional excipient and processing aid for industries requiring advanced molecular encapsulation, including pharmaceuticals, food and beverage, cosmetics, and agrochemicals.

Application

• Pharmaceutical Formulations: Used to improve the aqueous solubility, dissolution rate, and chemical stability of poorly soluble active pharmaceutical ingredients (APIs). It also masks unpleasant tastes and odors and can be used to convert liquids into solid powders.
• Food & Flavor Industry: Acts as a flavor carrier and stabilizer, protecting volatile aromas and sensitive compounds (like vitamins and unsaturated fats) from oxidation, light, and heat during processing and storage.
• Cosmetics & Personal Care: Functions as a delivery system for fragrances and active ingredients, controls the release of compounds, and stabilizes emulsions and formulations against degradation.
• Agrochemicals: Enhances the stability, solubility, and controlled release of pesticides, herbicides, and plant growth regulators, improving efficacy and reducing environmental impact.
• Chemical Separation & Analysis: Employed in chromatography as a chiral stationary phase for enantiomer separation and in various analytical techniques for sample preparation and purification.
• Environmental Remediation: Used to encapsulate and remove organic pollutants from water and soil due to its ability to form complexes with various organic molecules.

Quality Control

Our β-Cyclodextrin is manufactured under a strict quality management system. We offer grades compliant with major pharmacopoeial standards, including USP-NF, Ph. Eur., and JP, as well as food-grade specifications (FCC). Every batch undergoes comprehensive analytical testing to ensure identity, purity, and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and reduced performance.
