FAO:Potassium alginate
•it consists chiefly of sodium salt of alginic acid, polyuronic acid composed of beta d-mannuronic acid residues linked so that carboxyl group of each unit is free while aldehyde group is shielded by glycosidic linkage. •all derivatives of alginic acid designated by the generic term algin. most commonly used algin compound is sodium alginate often used interchangeably. •trade names include alginate, sfc; cecalgum, sanofi; dialgin, diamalt; keltex, kelco; lamitex, protan; manutex, kelco. •dental alginates are powder mixtures with the following composition: sodium alginate (10 ? 20 wt %), calcium sulfate (10 wt %), trisodium phosphate (1 ? 4 wt %), diatomite (70 ? 80 wt %), color and flavor (1 ? 2 wt %).
