Description

Cyclodextrin CAS NO 12619-70-4 is a family of cyclic oligosaccharides derived from starch, known for their unique conical structure with a hydrophilic exterior and a hydrophobic internal cavity. This molecular architecture enables them to form inclusion complexes with a wide variety of guest molecules, significantly enhancing solubility, stability, and bioavailability. It is an indispensable tool for formulation scientists across the pharmaceutical, food, cosmetic, and agrochemical industries seeking to overcome challenges with poorly soluble or unstable active ingredients.

Application

• Pharmaceutical Formulations: Used as a complexing agent to improve the aqueous solubility, dissolution rate, and chemical stability of active pharmaceutical ingredients (APIs), and to mask unpleasant tastes or odors.
• Food & Flavor Industry: Employed to stabilize sensitive flavors, fragrances, and colors against oxidation, heat, and light, and to control the release of ingredients in functional foods and nutraceuticals.
• Cosmetics & Personal Care: Functions to stabilize volatile fragrances and active compounds in creams and lotions, reduce skin irritation, and provide controlled release of ingredients.
• Agrochemicals: Enhances the stability, solubility, and efficacy of pesticides and herbicides, while potentially reducing environmental impact.
• Chemical Separation & Analysis: Serves as a chiral stationary phase in chromatography for the separation of enantiomers and isomers.
• Environmental Remediation: Utilized to encapsulate and facilitate the removal of organic pollutants from water and soil.

Quality Control

Our Cyclodextrin is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. We can supply material compliant with various pharmacopeial standards (e.g., USP-NF, Ph. Eur., JP) or Food Chemical Codex (FCC) grade, as required. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking and potential degradation.
