Contact SupplierSodium Alginate is a natural, water-soluble polysaccharide derived from brown seaweed (e.g., Laminaria, Macrocystis). It appears as a white to yellowish fibrous or granular powder, odorless and tasteless, forming viscous colloidal solutions in water. As a biopolymer, it exhibits exceptional gelling, thickening, stabilizing, and film-forming properties, controlled by interactions with calcium ions. Widely used in food, pharmaceuticals, textiles, and biotechnology, sodium alginate is prized for its biocompatibility, biodegradability, and non-toxic nature
