Description

Carboxymethylamylose Sodium Salt is a chemically modified starch derivative, specifically the sodium salt of carboxymethylated amylose. This compound is valued for its enhanced water solubility, thickening properties, and ability to form stable colloidal dispersions, making it a versatile functional polymer. It is primarily utilized in industries requiring advanced rheology modifiers, stabilizers, or film-forming agents, such as pharmaceuticals, food technology, and specialty chemical manufacturing.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, and controlled-release matrix in tablet and capsule formulations.
• Food Industry Additive: Functions as a thickener, stabilizer, and texture modifier in sauces, dressings, and dairy products.
• Cosmetics and Personal Care: Acts as a viscosity-increasing agent and stabilizer in lotions, creams, and hair care products.
• Paper and Textile Sizing: Employed as a coating and sizing agent to improve strength, printability, and finish.
• Industrial Applications: Serves as a suspending agent, protective colloid, and adhesive component in various chemical processes.
• Research and Development: Used in biochemical and material science research for its unique polymeric properties.

Quality Control

Our Carboxymethylamylose Sodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and functionality. While available in various grades (including technical and purified), we can provide material compliant with relevant standards for target applications. Certificates of Analysis (COA) documenting key parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
