Sodium Alginate 98%


SKU: N/A Categories: ,

Alginic acid, also called algin or alginate, is an anionic polysaccharide distributed widely in the cell walls of brown algae, where through binding with water it forms a viscous gum. In extracted form it absorbs water quickly; it is capable of absorbing 200–300 times its own weight in water. Its colour ranges from white to yellowish-brown.
