  • Applications

    Hydroxypropyl distarch phosphate (CAS 53124-00-8) is a modified starch used as a thickener, stabilizer, and viscosity modifier. In food processing, it improves texture and mouthfeel in sauces, soups, dairy products, and desserts, while enhancing freeze-thaw stability. In cosmetics and personal care, it serves as a thickener and emulsion stabilizer for creams, lotions, and gels. In coatings and inks, it functions as a rheology modifier to control flow, sag resistance, and pigment suspension. In starch-based adhesives and binders, it acts as a binder and thickener supporting film formation. In household and cleaning products, it helps stabilize and suspend ingredients, improving formulation uniformity and viscosity. In industrial manufacturing, it can be used as a processing aid to improve texture and stability of starch-based systems.
