Hydroxypropyl starch phosphate

Hydroxypropyl starch phosphate (CAS 113894-92-1) is a modified starch derivative produced by dual chemical modification to deliver controlled rheology and moisture retention across food and industrial applications.

The combined modification improves stability under processing conditions where native starches would break down. In food manufacturing, it functions as a thickener and stabilizer in sauces, dressings, and dairy-based products.

The material maintains texture through freeze-thaw cycles and heat processing. Textile finishing operations use it as a sizing agent to improve yarn strength and surface smoothness during weaving processes.

In paper and pulp production, it serves as a surface sizing and coating binder, improving printability and sheet integrity. Building material formulators incorporate it into tile adhesives and joint compounds.

These applications help to control water retention and open time in construction settings. Hydroxypropyl starch phosphate is supplied as a white to off-white powder for easy handling and formulation.

Food-grade material is available meeting specifications relevant to FCC and E 1442 compliant markets. Viscosity grades are selected to match specific processing requirements for various manufacturers.

Technical grades are also available for industrial applications in construction, paper, and textile sectors. This versatile starch derivative provides consistent performance across a wide range of pH levels and temperatures.
