Sodium alginate and alginate sodium, sodium alginate, sodium alginate, alginate gel, sodium alginate, kelp. The main component is sodium alginate, chitosan is a mixture of acid. Is a kind of gum extracted from brown algae such as kelp. White or light yellow powder, odorless, tasteless, moisture absorption, the relative density of 1.59 87.39kg/m3, bulk density, moisture content 13%, ash 23%, black to 150 degrees Celsius temperature, carbonization temperature of 340 degrees Celsius (460 degrees), ashing temperature of 480 DEG C, the heat of combustion of 10.46J/g, insoluble in ethanol, ether or chloroform etc.. Soluble in hot water and cold water, 1% aqueous solution pH value of 6 ~ 8, can form a viscous colloidal solution, and with protein, starch, pectin, Arabia gum, carboxymethyl cellulose, sucrose, glycerol and sorbitol blends. Dilute acid insoluble in pH less than 3. When the pH is 6 ~ 9, its viscosity is stable, heated to 80 degrees Celsius above its viscosity drop.
Application:

Polymer material, sodium alginate is suspending, thickening, emulsifying, adhesive and so on, in medicine is mainly used as a suspending agent, emulsifier, viscous agent, microcapsule capsule material etc.. As tablet binder (1% ~ 3%) and disintegrating agent (2.5% ~ 10%); used as a diluent in capsules; also used for the preparation of oral sustained-release preparation, because it can delay the drug from the aqueous suspension of release; in the paste, ointment and gel is widely used as a thickening agent and suspending agent (5% ~ 10%), and as a stabilizer in oil in water emulsions (1% ~ 3%) use. 0.5% ~ 2.5% aqueous solution can be used to smooth the skin erosion surface, can make the water discharge and drying out.
