Hydroxypropyl starchether (HPS) is widely used in the pharmaceutical industry as an excipient in tablet formulations. It acts as a binder, disintegrant, and filler, ensuring the tablet maintains its structure while allowing it to break down efficiently in the body. In the food industry, HPS serves as a thickening and stabilizing agent in products like sauces, soups, and dairy items, enhancing texture and consistency. It is also employed in the paper industry to improve paper strength and surface properties during manufacturing. Additionally, HPS finds use in cosmetics, where it functions as a viscosity modifier and emulsion stabilizer in creams and lotions, providing a smooth and stable product. It is further used in cleaning products to enhance cleaning efficiency and product stability. Its versatility and biocompatibility make it a valuable additive across various sectors.
