Description

Hydroxypropyl Starch Phosphate is a chemically modified starch derivative, where hydroxypropyl and phosphate groups are introduced to enhance its functional properties. This modification significantly improves its stability, clarity, and resistance to retrogradation and shear, making it a superior thickening and stabilizing agent. It is a critical ingredient for formulators in the food, pharmaceutical, and personal care industries seeking consistent performance and clean-label solutions.

Application

• Food Industry: Used as a thickener, stabilizer, and texture modifier in sauces, gravies, soups, dairy products, and low-pH beverages, providing excellent freeze-thaw stability and clarity.
• Pharmaceuticals: Serves as a binder, disintegrant, and controlled-release matrix in tablet formulations, offering improved compressibility and drug release profiles.
• Personal Care & Cosmetics: Functions as a film-former, viscosity enhancer, and stabilizer in creams, lotions, and hair care products, providing a smooth, non-tacky feel.
• Technical Applications: Employed as a sizing agent in paper and textile manufacturing, and as a biodegradable additive in adhesives and construction materials.

Quality Control

Our Hydroxypropyl Starch Phosphate is manufactured under strict quality management systems. Each batch is tested to ensure it meets relevant specifications for food (FCC, INS 1442) and pharmaceutical (where applicable) grades. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as degree of substitution, viscosity, pH, and microbial limits to guarantee product consistency and safety.

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 and degradation due to moisture absorption.
