Sodium alginate, identified by CAS 9005-38-3, is a highly versatile polysaccharide extracted from brown seaweed. It is renowned for its unique ability to form gels and viscous solutions when hydrated, making it an indispensable ingredient in numerous industries, including food, pharmaceuticals, and cosmetics. For professionals in these fields, understanding the detailed properties and application benefits of sodium alginate is key to optimizing formulations and ensuring product quality. This guide aims to provide insights into its characteristics and offers advice on how to procure this essential chemical.

As a raw material, sodium alginate typically presents as a white to pale yellow powder. Its primary functional attributes include thickening, stabilizing, and gelling. These properties stem from its long polymer chains, composed of mannuronic and guluronic acid units. The viscosity of sodium alginate solutions can vary significantly based on the specific grade and processing, which is a critical parameter for formulators to consider when they intend to buy. For instance, in the food industry, lower viscosity grades might be used in beverages, while higher viscosity grades are preferred for products like jams and fillings. Similarly, in pharmaceuticals, specific viscosity profiles are required for suspensions and controlled-release formulations.

The application spectrum of sodium alginate is extensive. In the food sector, it's a common additive in dairy products, desserts, and dressings to improve texture and stability. Pharmaceutically, it acts as an excipient, contributing to the efficacy and delivery of medications. It's also used in wound dressings due to its biocompatibility and moisture-retaining capabilities, promoting healing. For those in the cosmetics industry, it serves as a stabilizer and thickener in creams and lotions. Given its widespread use, securing a consistent and high-quality supply is essential. When looking to purchase sodium alginate, identifying manufacturers who can provide detailed product specifications, including purity assays and viscosity data, is paramount.
