Description

Hydroxypropyl Starch is a modified starch derivative, produced by the etherification of native starch with propylene oxide, resulting in enhanced stability and functional properties. This modification is critical for applications requiring superior resistance to retrogradation, freeze-thaw cycles, and acidic conditions compared to unmodified starches. It serves as a key functional ingredient for formulators in the food, pharmaceutical, and industrial sectors seeking reliable texture modification and binding agents.

Application

• Food Industry: Acts as a thickener, stabilizer, and texturizer in sauces, gravies, frozen foods, and dairy products, providing improved clarity and shelf stability.
• Pharmaceuticals: Used as a binder, disintegrant, and film-forming agent in tablet formulations, offering excellent compressibility and controlled release profiles.
• Personal Care & Cosmetics: Functions as a viscosity modifier, emulsion stabilizer, and texture enhancer in lotions, creams, and hair care products.
• Paper & Adhesives: Employed as a surface sizing agent and binder to improve paper strength, printability, and adhesive performance.
• Textile Industry: Serves as a warp sizing agent to protect yarns during weaving, offering good film-forming and easy removal properties.

Quality Control

Our Hydroxypropyl Starch is manufactured under a strict quality management system. Production adheres to relevant standards such as Food Chemical Codex (FCC) and USP-NF for applicable grades, ensuring consistency and safety for intended use. Every batch is tested against stringent specifications for identity, purity, and functionality. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed after opening to prevent caking or degradation due to moisture absorption. Keep away from strong oxidizing agents.
