Description

α-Cyclodextrin is a cyclic oligosaccharide composed of six α-(1,4)-linked D-glucopyranose units, forming a truncated cone structure with a hydrophobic internal cavity. This unique molecular architecture enables it to form inclusion complexes with a wide variety of guest molecules, significantly enhancing their solubility, stability, and bioavailability. As a key excipient and molecular encapsulation agent, it is essential for industries focused on advanced formulation science, including pharmaceuticals, nutraceuticals, and specialty chemicals.

Application

• Pharmaceutical Formulations: Used as a complexing agent to improve the aqueous solubility, dissolution rate, and chemical stability of poorly soluble active pharmaceutical ingredients (APIs).
• Food & Flavor Industry: Acts as a stabilizer and delivery system for volatile flavors, fragrances, and sensitive nutrients, protecting them from oxidation, heat, and light degradation.
• Cosmetics & Personal Care: Employed to solubilize active ingredients, control odor release, and enhance the stability of formulations in creams, lotions, and serums.
• Analytical Chemistry & Separation Science: Serves as a chiral selector in capillary electrophoresis and HPLC columns for the enantiomeric separation of racemic mixtures.
• Chemical Synthesis & Catalysis: Functions as a green, water-soluble host in supramolecular chemistry to modify reaction rates, selectivity, and to stabilize reactive intermediates.
• Agrochemicals: Enhances the stability and controlled release of pesticides and herbicides, improving their efficacy and environmental profile.

Quality Control

Our α-Cyclodextrin is manufactured under a strict quality management system. We offer grades suitable for various applications, including pharmaceutical (USP/EP), food (FCC), and high-purity research standards. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles to ensure compliance with your specific requirements.

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 and caking.
