Description
A hydrophilic polysaccharide obtained from Seaweed. Alginic acid is a stable, light yellowish fibrous solid or powder that is capable of absorbing over 200 times its weight in water. It is used as a thickener and emulsifier in food, ice cream, toothpaste, and cosmetics. Alginic acid forms water-insoluble polymeric alginates with most divalent cations (Ca++, Ba++, etc.), which are used for textile sizing, paper coatings, and to produce imitation Horn, Ivory, and Celluloid.
