Description

Starch, 2-Hydroxyethyl Ether, Oxidized is a chemically modified starch derivative, also known as oxidized hydroxyethyl starch (HES). This compound is engineered to offer superior solubility, stability, and rheological properties compared to native starch. It is a critical functional ingredient for industries requiring effective thickening, stabilizing, and film-forming agents. Key sectors that utilize this product include pharmaceuticals, food processing, paper manufacturing, and textile production.

Application

• Pharmaceutical Formulations: Used as a plasma volume expander and as an excipient in tablet binding and coating.
• Food Industry: Functions as a thickener, stabilizer, and texturizer in sauces, soups, and dairy products.
• Paper Manufacturing: Serves as a surface sizing agent and coating binder to improve paper strength and printability.
• Textile Processing: Applied in warp sizing to protect yarns during weaving and as a finishing agent.
• Adhesives & Construction: Acts as a biodegradable binder and viscosity modifier in adhesives, mortars, and gypsum boards.
• Personal Care Products: Utilized as a viscosity-increasing agent and stabilizer in lotions, creams, and hair care formulations.

Quality Control

Our Starch, 2-Hydroxyethyl Ether, Oxidized is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for parameters such as degree of substitution, molecular weight distribution, viscosity, and purity. Certificates of Analysis (COA) are provided with every shipment. We can supply grades compliant with relevant pharmacopeial (e.g., USP, EP) and food (FCC) standards upon request.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
