Description

Sodium Polypectate CAS NO 9049-37-0 is the sodium salt of polygalacturonic acid, a high-molecular-weight polysaccharide derived from pectin. This compound serves as a versatile hydrocolloid and gelling agent, valued for its ability to form stable, clear gels in the presence of calcium ions. It is essential for manufacturers in the food, pharmaceutical, and cosmetic industries seeking precise texture control and stabilization.

Application

• Food Industry: Used as a gelling agent, thickener, and stabilizer in jams, jellies, fruit preparations, and dairy products.
• Pharmaceuticals: Employed as a binding and disintegrating agent in tablet formulations and as a suspending agent in liquid preparations.
• Cosmetics & Personal Care: Functions as a film-forming agent, viscosity modifier, and stabilizer in creams, lotions, and gels.
• Microbiological Media: Acts as a solidifying agent in culture media for the isolation and identification of pectinolytic microorganisms.
• Analytical Chemistry: Utilized as a clarifying agent and in methods for determining pectinase activity.
• Textile & Paper: Serves as a sizing agent and coating additive to improve strength and surface properties.

Quality Control

Our Sodium Polypectate is produced and tested under a strict quality management system to ensure batch-to-batch consistency and reliability. We offer grades suitable for food (FCC), pharmaceutical, and technical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, viscosity, and gel strength. Certifications including ISO and GMP compliance are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
