Description

A gelling polysaccharide compound found in giant brown seaweed of the class Phaeophyceae. Algin is similar to Agar. It is composed of mannuronic acid and glucuronic acids. The hydrophilic, cream-color material is extracted from the kelp and used as thickener and stabilizer in coatings and food products, such as ice cream. It is also used to produce synthetic yarns and fibers and as a blood coagulant in first aid dressings. The name algin is also used as a shortened version of Alginic acid and Sodium alginate.

Synonyms and Related Terms

sodium alginate; sodium salt of alginic acid; sodium polymannuronate; Alto; Alman; Alloid; Allose; Kelgin; Protanal; dental alginate

Risks

Fisher Scientific: MSDS

Physical and Chemical Properties

Soluble in water, forming a viscous solution. Insoluble in ethanol, chloroform, ether and in acidic solutions of pH
