Sodium alginate, a polysaccharide derived from brown seaweed and identified by CAS 9005-38-3, is renowned for its distinctive viscosity and gelation properties, which are fundamental to its widespread application across various industries. For product developers, formulators, and procurement specialists, understanding these rheological characteristics is key to selecting the appropriate grade of sodium alginate for optimal performance. As a prominent manufacturer and supplier, we offer a range of sodium alginate products tailored to meet specific viscosity and gelation requirements.

The viscosity of sodium alginate solutions is influenced by several factors, including its molecular weight, concentration, and the degree of polymerization of the mannuronic and guluronic acid residues. Higher molecular weight and increased concentration generally lead to greater viscosity. This property is critical in applications where thickening is desired, such as in sauces, yogurts, and cosmetic formulations. Manufacturers seeking to buy sodium alginate for specific viscosity needs can rely on our product portfolio, which often specifies viscosity ranges (e.g., 300-400 cps, 500-600 cps, or higher). Sourcing from a reputable manufacturer ensures that the viscosity specifications are consistently met batch after batch, which is essential for reproducible product quality.

Perhaps the most unique characteristic of sodium alginate is its ability to undergo gelation in the presence of divalent cations, most notably calcium ions. This process, known as ionotropic gelation, allows sodium alginate to form stable, three-dimensional networks. The strength and texture of these gels can be manipulated by varying the concentration of calcium ions, the ratio of mannuronic to guluronic acid, and the processing conditions. This gelation capability is exploited in diverse applications, from creating spherified foods and microencapsulation technologies to developing advanced wound dressings and tissue engineering scaffolds. For those looking to purchase sodium alginate for gelation applications, understanding the specific composition and grade required is vital.
