CAS NO.: 9005-38-3 Molecular Formula: C6H7O6Na Molecular weight: 216

Synonyms: Sodium Alginate, Alginic Acid Monosodium Salt, Algin, Alginic

Acid Sodium Salt from Brown Algae


Sodium alginate, also called algin, is one kind of electrolyte of organic macromolecule among algae of brown algae types, such as kelp, as principal components of cell membrane with other substances. Sodium alginate food grade is in the form of ivory-white granule or powder, odourless, low odor of sourness.

Chemical components of sodium alginate belong to carbohydrate and it only contains free carboxyl (-COONa) in contrast with starch and fibrin. At the same time, it is one kind of chain type macromolecule heteropolymer brought by copolymerization between mannuronic acid and guluronicacid.

Polymerization Degree of sodium alginate differs according to raw materials and distilling methods. Generally speaking, degree of polymerization of common algin is within the range from 80 to 750, molecular weight is from 14000 to 132000. Equivalent weight of sodium alginate is 196.

Sodium alginate does not dissolve to methanol, ethanol, acetone and chloroform; Dissolve to sodium hydroxide liquid and water; Monatomic base alkali salt, such as soduim salt and sylvite, as well as ammonium salt, magnesium salts and mercury salt all dissolve to water and become into thick liquid. Multivalent metal salt of algin does not dissolve to water, except magnesium salts and mercury salt.

Water-soluble Sodium alginate can substitute dispersant of some rosin paper pulp or paper sizing for paper making, then smoothness of paper surface can be enhanced. At the same time, it can regulate absorption of printing ink, wax and oil to enhance its resistance to massage. Cladding of welded bar: After mixing arc welding electrodes with Sodium alginate, alginato de potassio and calcium alginate, cladding of medical materials can be conglutinated, therefore enough plasticity can be gained in the extruding process. At the same time, it can be easily burned, thus splash can be lessened.

Packake and Storage:

P. P. Woven or craft paper bags with 25KG net each, keep dry
