Alginic Acid powder Usage and Synthesis.

The main component of sodium alginate is the sodium salt of alginic acid, which is a mixture of polyuronic acid. Sodium alginate is widely used in pharmaceutical preparations, food and cosmetics. It is an almost non-toxic and non-irritating substance.

The gel formed by sodium alginate and calcium ions has the characteristics of freeze resistance and water absorption and swelling recovery after drying. The viscosity of sodium alginate affects the brittleness of the formed gel. The higher the viscosity, the brittler the gel.

The gel obtained by increasing the concentration of calcium ions and sodium alginate has increased strength. The gel formation process can be controlled by adjusting the pH, selecting appropriate calcium salts and adding phosphate buffers or chelating agents. It can also be controlled by gradually releasing multivalent cations or hydrogen ions, or both.

Uses and functions of Alginic Acid.

In the pharmaceutical industry, it is used to make drugs such as stomach-covering drugs, and is also used as an excipient, disintegrant, binder and stabilizer for tablets; it is often used as a stabilizer, thickener, emulsifier, etc. in food and cosmetics. When used, it is generally processed into sodium salts. Emulsifier. Protective colloid. It is a pharmaceutical excipient, used as a binder, disintegrant, thickener, and suspending agent for tablets.

Advantage of Alginic Acid.

Product Method of Bulk Alginic Acid.

Various brown algae (such as kelp, giant kelp, etc.) are washed with acidic water containing dilute hydrochloric acid to remove attached iodine, mannitol, salt, laminin, fucoidan, etc., and then stirred and extracted with sodium hydroxide or sodium carbonate solution.
