alginic acid
methyl 4-O-(4-O-methylhexopyranuronosyl)hexopyranosiduronic acid
marine algal polysaccharide; a linear copolymer consisting mainly of beta-1,4-linked d-mannuronic acid and alpha-1,4-linked l-glucuronic acid; xantalgin is a dental impression material. Alginates are used to improve food texture, e.g. in ice cream, pie fillings. Emulsifier, stabiliser, thickener Alginic acid, also called algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where it, through binding water, forms a viscous gum. In extracted form it absorbs water quickly; it is capable of absorbing 200-300 times its own weight in water.[1] Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular or powdered forms. (Wikipedia)

FAO: Alginic acid
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 %).
