Product Description

 

                                                          Sodium Alginate

Sodium alginate is a by-product after iodine and mannitol are extracted from kelp or sargassum of brown algae, and its molecule
consists of β-D-mannuronic (β-D-mannuronic, M) and α-L-guluronic (α-L-guluronic, G) connected by (1→4) bond, which is a kind
of natural polysaccharides, with the stability, solubility, adhesion, and safety of excipients required for the pharmaceutical preparations
and safety. Sodium alginate has been widely used in the food industry and pharmaceutical field.

Physical and Chemical Properties
Sodium alginate is white or light yellow powder, almost odourless and tasteless. Sodium alginate is soluble in water, insoluble in
ethanol, ether, chloroform and other organic solvents. Dissolved in water into a viscous liquid, 1% aqueous solution pH value of 6-8.
viscosity is stable when pH = 6-9, viscosity decreases when heated to 80 ºC or more. Sodium alginate is non-toxic, LD50>5000mg/kg.
chelating agent on the nature of sodium alginate solution chelating agent can be complexed with the divalent ions in the system, so
that sodium alginate can be stabilised in the system.
