Pharmaceutical Grade Alginic Acid Thickener Raw Material F

Pharmaceutical Grade Alginic Acid Thickener Raw Material For Gastropine

1. Quick Detail:

Alginic acid is a natural polysaccharidc cxtractcd from seaweed. It is made of the two types of aldehyde acids. Flaxen powder, isn' t soluble in water.

2. Description :

Alginic acid, a polysaccharide extracted from kelp-like Phaeophyceae, formed by α-L-Mannuronic acid (M section) and β-D-Guluronic acid (G section) connected through 1,4-glucosidic bond. The acid is instability state and can react with positive metal ion to form alginate series production.
Molecular formula : (C6H8O6) n
Properties : White or light yellow powder, insoluble in water, odorless and almost tasteless.

3. Applications :

A. Pharmaceutical industry:

Main raw material for gastropine. Agent for the new medicine PSS,With the strong dispersing and emulsifying character.

B . Food industry:
