Description

Hydroxypropyl Starch Phosphate is a chemically modified starch derivative, known for its enhanced stability and functional properties. This compound is valued for its ability to act as a superior thickener, stabilizer, and emulsifier in demanding formulations. It is essential for manufacturers in the food, pharmaceutical, and personal care industries seeking consistent performance and improved texture in their products.

Application

• Food Industry: Used as a thickener, stabilizer, and texturizer in sauces, gravies, soups, dairy products, and low-pH beverages.
• Pharmaceuticals: Serves as a binder, disintegrant, and controlled-release matrix agent in tablet formulations.
• Personal Care & Cosmetics: Functions as a viscosity modifier and stabilizer in lotions, creams, and hair care products.
• Industrial Applications: Acts as a sizing agent in paper manufacturing and a thickener in water-based adhesives.
• Oil Field Drilling: Employed as a fluid loss control additive and viscosifier in drilling muds.
