Hydroxypropyl Starch Ether (HPS)
Hydroxypropyl starch ether (HPS) is a non-ionic, water-soluble polymer compound obtained by chemical etherification modification of natural starches (corn starch, tapioca starch, potato starch, waxy corn starch, etc.). It retains the advantages of the natural source of starch while significantly improving the water solubility, stability, and processing performance of the original starch by introducing hydroxypropyl groups.
