CAS 9049-76-7

Hydroxypropyl starch

Description:

Hydroxypropyl starch, identified by the CAS number 9049-76-7, is a modified starch derived from natural starch sources through a chemical process that introduces hydroxypropyl groups. This modification enhances its solubility in cold water and improves its stability under varying pH and temperature conditions, making it a versatile ingredient in various applications. Hydroxypropyl starch is commonly used as a thickening agent, stabilizer, and emulsifier in food products, pharmaceuticals, and cosmetics. Its ability to form gels and films contributes to its functionality in these industries. Additionally, it is generally recognized as safe (GRAS) for consumption, which further supports its widespread use. The substance is characterized by its white to off-white powder form, and it is typically odorless and tasteless. Hydroxypropyl starch is also valued for its non-toxic nature and compatibility with other ingredients, making it an essential component in formulations requiring enhanced texture and stability.

Hydroxypropyl starch

CAS: 9049-76-7

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.
