Sodium Alginate is a water-swollen, cross-linked polymer that is a product of a simple chemical reaction between monomers. It is a great water absorber, as structurally, the hydrophilic groups are attached to its polymeric backbone. It is resistant to dissolution because of the cross-linked network chains.


Sodium Alginate is the sodium salt form of alginic acid mainly extracted from the cell walls of brown algae, with chelating activity. Alginates reacts with calcium ions and form thermo-irreversible gel so, It is also widely used in molecular gastronomy. It is a white powder, odourless and tasteless, slowly soluble in cold water forming a viscous solution. Sodium alginate is widely used in food, pharmaceutical, Cosmetic, impression and dental grade.
