Description

Starch, Hydrogen Phosphate, 2-Hydroxypropyl Ether is a chemically modified starch derivative, specifically a phosphate ester of hydroxypropyl starch. This modification imparts enhanced functional properties, making it a valuable ingredient for demanding industrial and food-grade applications where stability and performance are critical. It is primarily utilized in the food industry as a thickener and stabilizer, as well as in pharmaceutical formulations and various technical processes.

Application

• Food Industry: Acts as a highly effective thickener, stabilizer, and texturizing agent in sauces, gravies, soups, and dairy products, providing excellent freeze-thaw stability and clarity.
• Pharmaceuticals: Serves as a versatile excipient in tablet formulations, functioning as a binder and disintegrant, and as a stabilizer in topical creams and ointments.
• Paper Manufacturing: Used as a wet-end additive and surface sizing agent to improve paper strength, printability, and surface smoothness.
• Textile Industry: Employed in warp sizing to protect yarns during weaving, offering good adhesion and easy removal.
• Adhesives & Construction: Functions as a biodegradable and renewable component in adhesive formulations and as an additive in building materials like gypsum boards.
• Personal Care: Incorporated into cosmetic and personal care products such as lotions and powders for its texture-modifying and moisture-managing properties.

Quality Control

Our Starch, Hydrogen Phosphate, 2-Hydroxypropyl Ether is manufactured under strict quality management systems. We offer grades compliant with relevant food additive specifications, including FCC (Food Chemicals Codex) and JECFA standards for food applications, and pharmaceutical-grade material where required. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation from atmospheric moisture.
