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. Also known as E 1442.

Where is Hydroxypropyl starch phosphate used?

• Food manufacturing: thickener and stabilizer in sauces, dressings, and dairy-based products
• Textile finishing: sizing agent improving yarn strength and surface smoothness during weaving
• Paper and pulp: surface sizing and coating binder improving printability and sheet integrity
• Building materials: water retention and open time control in tile adhesives and joint compounds
• The combined modification improves stability under processing conditions where native starches would break down.

Good to know: Viscosity grades are selected to match specific processing requirements; technical grades are also available for construction, paper, and textile sectors.

Commercial specifications

• Food-grade material meeting FCC and E 1442 specifications
