Product Details

Sodium alginate is the sodium form of alginate. Alginate is a linear, anionic polysaccharide consisting of two form of 1, 4-linked hexuronic acid residues, β-d-mannuronopyranosyl (M) and α-l- guluronopyranosyl (G) residues. It can be arranged in the form of blocks of repeating M residues (MM blocks), blocks of repeating G residues (GG blocks), and blocks of mixed M and G residues (MG blocks). Commercially available alginate currently originates from algae. Alginate has wide applications. For example, one of its most important role is being used as wound dressing materials for the treatment of acute or chronic wounds. The use of alginate crosslinking to make hydrogels for cell encapsulation is also quite valuable. The emergence of various kinds of its derivatives recently has further extended its application.

Product Application of Sodium Alginate CAS#9005-38-3

Sodium Alginate is a gum obtained as a sodium salt of alginic acid, which is obtained from seaweed. it is coldand hot-water soluble, producing a range of viscosities. it forms irreversible gels with cal- cium salts or acids. it functions as a thickener, binder, and gelling agent in dessert gels, puddings, sauces, toppings, and edible films. In the manufacture of ice cream where it serves as a stabilizing colloid, insuring creamy texture and preventing the growth of ice crystals. In drilling muds; in coatings; in the flocculation of solids in water treatment; as sizing agent; thickener; emulsion stabilizer; suspending agent in soft drinks; in dental impression preparations. Pharmaceutic aid (suspending agent).
