Description

β-Cyclodextrin Phosphate Sodium Salt is a chemically modified cyclodextrin derivative where phosphate groups are introduced to enhance its solubility and complexation properties. This modification is critical for creating stable, water-soluble inclusion complexes with a wide range of hydrophobic guest molecules, significantly broadening its utility in advanced formulations. It is an essential functional excipient and delivery agent for industries focused on improving the bioavailability, stability, and controlled release of active ingredients.

Application

• Pharmaceutical Formulations: Used as a solubility enhancer and stabilizer for poorly water-soluble drugs, improving their bioavailability and dissolution rates.
• Nutraceutical & Food Additives: Employed to encapsulate flavors, vitamins, and sensitive bioactive compounds, protecting them from degradation and masking unpleasant tastes.
• Cosmetic & Personal Care: Functions as a delivery system for active ingredients in creams and serums, controlling release and enhancing skin penetration.
• Analytical Chemistry & Separation Science: Serves as a chiral selector or stationary phase modifier in capillary electrophoresis and chromatography for enantiomer separation.
• Agrochemicals: Used to formulate pesticides and herbicides, enhancing their stability, solubility, and reducing environmental volatility.
• Research & Development: A key tool in supramolecular chemistry for studying host-guest interactions and developing new sensor materials or catalysts.

Quality Control

Our β-Cyclodextrin Phosphate Sodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters such as assay, degree of substitution, residual solvents, and microbiological quality. Production can adhere to relevant guidelines for pharmaceutical (cGMP), food (FCC), or research-grade materials based on customer 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 (typically 15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent absorption of moisture from the air, which can affect product performance and stability.
