Description

Starch, Hydrogen Phosphate Acetate is a chemically modified starch derivative, specifically a phosphate acetate ester. This modification imparts unique functional properties, making it a valuable ingredient for demanding industrial and food-grade applications where native starches fall short. It is particularly sought after by manufacturers in the food, pharmaceutical, and paper industries for its enhanced stability and performance as a thickener, stabilizer, and binder.

Application

• Food Industry: Acts as a high-performance thickener, stabilizer, and texturizer in sauces, gravies, soups, and frozen foods, offering improved freeze-thaw stability and resistance to high-temperature processing.
• Pharmaceuticals: Used as a binder and disintegrant in tablet formulations, and as a viscosity modifier in topical creams and lotions.
• Paper Manufacturing: Employed as a wet-end additive and surface sizing agent to improve paper strength, printability, and ink holdout.
• Textile Industry: Serves as a warp sizing agent to protect yarns during weaving, providing a smooth, strong film that is easily removed later.
• Adhesives: Functions as a key component in specialty adhesives and glues, contributing to viscosity and binding properties.
• Biodegradable Materials: Investigated for use in the production of biodegradable plastics and films as a renewable polymer component.

Quality Control

Our Starch, Hydrogen Phosphate Acetate is produced under a strict quality management system. For food-grade material, production adheres to relevant sections of the Food Chemicals Codex (FCC) and is manufactured in compliance with GMP principles. All batches undergo comprehensive analytical testing to ensure consistent performance. A Certificate of Analysis (COA) detailing key parameters such as degree of substitution, residual solvents, and microbiological counts is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent caking or degradation due to moisture absorption. Keep away from strong oxidizing agents.
