Structural formula:

1. Performance and use:

Sodium alginate can be used as a flavorless gum.

Sodium alginate is used by the foods industry to increase viscosity and as an emulsifier.

Sodium alginate is also used in indigestion tablets and the preparation of dental impressions.

Sodium alginate (NaAlg) and its modified forms have been widely used as membranes in pervaporation (PV) separation of aqueous‐organic solutions because of the hydrophilic nature and versatility to modify/tune their structures to achieve the desired separation.

Sodium alginate is a polymer which can be extracted from brown seaweed and kelps. It is one of the structural polymers that help to build the cell walls of these plants. It has some unusual properties and a wide variety of uses.

Sodium alginate is used as a sizing agent and printing paste for textiles, and is widely used in food industry as a thickening agent, stabilizer and emulsifier.
