CAS 9049-76-7 Hydroxypropyl starch
Hydroxypropyl Starch CAS 9049-76-7: A Comprehensive Guide
Hydroxypropyl starch, recognized by its CAS number 9049-76-7, is a modified starch widely used in various industries. This modified starch is created by etherifying starch with propylene oxide, offering enhanced properties such as higher solubility, improved transparency, and better freeze-thaw stability. With these advantageous characteristics, hydroxypropyl starch finds applications in food, pharmaceuticals, textiles, and more.
Applications of Hydroxypropyl Starch
Food Industry
In the food sector, hydroxypropyl starch is used as a thickener, stabilizer, and emulsifier. It improves texture, shelf-life, and appearance in products such as soups, sauces, and dairy goods. Its stability under freezing and thawing conditions makes it particularly valuable for frozen foods.
Pharmaceuticals
Hydroxypropyl starch is employed in pharmaceuticals as a binder and disintegrant in tablet formulations. It enhances the stability and bioavailability of active ingredients, ensuring effective and consistent drug delivery.
Textiles
In textiles, this modified starch is used for sizing and finishing fabrics. It imparts a smooth finish, reduces friction during weaving, and enhances fabric strength, making it an essential component in textile manufacturing.
Cosmetics
Hydroxypropyl starch also finds applications in the cosmetics industry. It is used as a thickening agent in creams and lotions, providing a smooth texture and consistency. Its non-irritating nature makes it suitable for sensitive skin products.
Substance Identification
EC (European Community) Number
The EC Number is the numerical identifier for substances in the EC Inventory, combining lists from previous EU chemicals regulatory frameworks. For substances not covered by the EC Inventory, ECHA assigns a list number beginning with 6, 7, 8, or 9, serving as the primary identifier.
CAS (Chemical Abstract Service) Registry Number
The CAS number, assigned by the Chemical Abstracts Service of the American Chemical Society, is a unique numerical identifier for substances. It enables easy and precise identification of chemicals in various databases and regulatory frameworks.
Molecular Formula
The molecular formula of hydroxypropyl starch denotes the types and numbers of atoms in each molecule. This information is crucial for understanding its chemical properties and reactions. Often expressed in empirical form, the formula guides chemical synthesis and application methods.
