Sodium alginate
Natural and Biodegradable: Sodium alginate is a natural polysaccharide derived from seaweed, characterized by its non-toxic nature and biodegradability, making it an environmentally sustainable material.
Excellent Biocompatibility: It demonstrates outstanding biocompatibility, qualifying it for advanced applications in pharmaceutical formulations and biomedical engineering.
Water Solubility: The compound exhibits excellent hydrosolubility, forming viscous hydrocolloidal solutions in aqueous environments, particularly valuable in food processing and textile industries.
Wide Application Range: Owing to these combined properties, sodium alginate is extensively utilized across food, pharmaceutical, textile, and packaging sectors.
Sodium alginate (CHONa), being the primary sodium salt form of alginate, is a naturally occurring polysaccharide biopolymer recognized for its wide availability, non-toxic nature, biodegradability, and high biocompatibility. These properties make it highly valuable in fields such as biomedical engineering (e.g., wound dressings, drug delivery), food technology (e.g., thickener, stabilizer), textile printing, and sustainable packaging material development.
