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 is an essential 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 bakery fillings, providing excellent clarity and shelf stability.
• Pharmaceuticals: Serves as a binder, disintegrant, and controlled-release matrix in tablet formulations, offering consistent compression properties.
• Personal Care & Cosmetics: Used as a viscosity modifier, emulsion stabilizer, and texture enhancer in lotions, creams, and hair care products.
• Paper & Adhesives: Functions as a sizing agent and binder to improve paper strength and as a component in water-based adhesive formulations.
• Textile Printing: Employed as a thickener in pigment printing pastes for precise dye application and sharp print definition.

Quality Control

Our Hydroxypropyl Starch is manufactured under a rigorous quality management system. Production adheres to relevant standards such as Food Chemical Codex (FCC) and pharmaceutical-grade guidelines where applicable. Every batch is tested for critical parameters including degree of substitution, viscosity, pH, and microbial limits. A comprehensive Certificate of Analysis (COA) is provided with each shipment to ensure traceability and compliance with your specifications.

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 storage area must have low humidity to prevent caking and maintain product integrity. Keep away from strong oxidizing agents.
