Descrição

Hydroxypropyl starch is an amorphous, water-soluble polysaccharide with a molecular weight of about 10,000 Daltons. It contains a mixture of linear and branched polymers of glucose, maltose, and other sugars. Hydroxypropyl starch is used as an excipient in pharmaceutical products to stabilize the active ingredients. This product is prepared by reacting starch with propylene oxide in the presence of hydrochloric acid. The reaction mechanism is thought to be the breaking of glycosidic bonds in starch by hydrochloric acid and the formation of ester bonds between the hydroxyl groups on propylene oxide and those on the carbohydrate chains. Hydroxypropyl starch has been shown to have no long-term toxicity or adverse effects on chemical structures when injected into rats for 18 months.
