Description

Starch, 2-Hydroxypropyl Ether, Oxidized is a chemically modified starch derivative, also known as oxidized hydroxypropyl starch, designed for enhanced functional performance. This dual modification imparts superior stability, clarity, and binding properties compared to native starch, making it a critical functional ingredient. It is essential for industries requiring high-performance, water-soluble polymers for texture modification, film formation, and stabilization.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, and film-forming agent in tablet and capsule formulations.
• Food Industry: Functions as a thickener, stabilizer, and texturizer in sauces, dressings, and dairy products, improving mouthfeel and freeze-thaw stability.
• Paper & Corrugating: Serves as a surface sizing and coating agent to enhance paper strength, printability, and oil resistance.
• Textile Warp Sizing: Provides a protective, lubricating coating on yarns to reduce breakage during weaving.
• Adhesive Formulations: Acts as a biodegradable and renewable component in remoistenable adhesives for envelopes and labels.
• Personal Care & Cosmetics: Utilized as a texture enhancer, viscosity modifier, and absorbent in creams, lotions, and powders.

Quality Control

Our Starch, 2-Hydroxypropyl Ether, Oxidized is manufactured under strict quality systems. Each batch is tested to ensure it meets relevant specifications for food (FCC, INS 1442) and pharmaceutical (USP/NF, EP) grades where applicable. Certificates of Analysis (COA) documenting purity, degree of substitution, and oxidation level are available upon request to support your regulatory and quality assurance needs.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
