Hydroxypropyl starch is a kind of chemically modified starch, which is etherified by propylene oxide and starch to replace the hydroxyl group in the starch polymer structure and become an etherified starch
Hydroxypropyl starch ether (HPS) is a fine white powder obtained from natural plants after modification, highly etherification reaction, and then spray drying, without plasticizers. It is completely different from ordinary starch or modified starch.
