Description

β-Cyclodextrin/ Epichlorohydrin Copolymer is a chemically cross-linked, water-soluble polymer derived from the reaction of β-cyclodextrin with epichlorohydrin. This material is valued for its enhanced stability and superior capacity to form inclusion complexes with a wide range of guest molecules compared to native cyclodextrins. It serves as a critical functional material for industries requiring advanced molecular encapsulation, controlled release, and separation technologies.

Application

• Pharmaceutical Formulations: Used as a solubility enhancer and stabilizer for poorly soluble active pharmaceutical ingredients (APIs) in oral and topical drug delivery systems.
• Food & Beverage Industry: Acts as a flavor/odor masking agent, a stabilizer for sensitive compounds, and a clarifier in beverages.
• Cosmetics & Personal Care: Functions to encapsulate fragrances, vitamins, and active ingredients to improve stability, reduce volatility, and control release in creams and lotions.
• Environmental Remediation: Employed in water treatment and pollution control for the selective adsorption and removal of organic pollutants, dyes, and heavy metals from wastewater.
• Chromatography & Separation Science: Serves as a stationary phase or additive in chromatographic columns for the enantiomeric separation of chiral compounds.
• Agrochemicals: Used to formulate controlled-release pesticides and herbicides, improving efficacy and reducing environmental impact.
• Textile & Paper Processing: Applied for odor control, dye complexation, and as a finishing agent to impart specific functional properties.

Quality Control

Our β-Cyclodextrin/ Epichlorohydrin Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and purity. Specifications are aligned with industry requirements for pharmaceutical, food, and technical applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, residual solvents, and other critical parameters is provided with every shipment.

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 affect performance.
