9005-38-3
Sodium alginate
CAS 9005-38-3
Alias：Alginic Acid Sodium Salt, Technical Grade; Sodium alginate, AR,90%
Molecular formula：C5H7O4COONa
Molecular weight：0
Structural formula：
1.Performance and use
Sodium alginate is also known as sodium alginate, sodium fucoidan, sodium alginate, fucoidan, kelp gum, sodium alginate. The main composition is the sodium salt of alginate, a mixture of polyglucuronic acid. It is a kind of gum extracted from brown seaweeds such as kelp. It is white or light yellow powder, odorless, tasteless, moisture-absorbent, relative density 1.59, bulk density 87.39kg/m3, moisture content 13%, ash 23%, blackening temperature 150℃, carbonization temperature 340℃(460℃), ashing temperature 480℃, heat of combustion 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 easy to mix with proteins, starch, pectin, gum arabic, carboxymethyl cellulose, sucrose, propanetriol and sorbitol. Insoluble in dilute acid with pH less than 3. When the pH is 6-9, its viscosity is stable, and its viscosity decreases when heated above 80℃.
Sodium alginate can help suspension, thickening, emulsification, adhesion, etc. It is mainly used as suspending agent, emulsifier, viscous agent, capsule material of microcapsules, etc. in pharmaceuticals.
