Product Details

Products Description of Alginic acid CAS#9005-32-7

Alginic acid is a viscous organic acid, also known as alginic acid and alginic acid. The product is white to light yellow-brown powder. The average molecular weight is about 240,000. Melting point>300℃. It is slightly soluble in hot water, and the viscosity of its aqueous solution is 4 times higher than that of starch. It is insoluble in cold water and organic solvents, and slowly dissolves in alkaline solutions. It has no odor.

In nature, it is widely present in the cell walls of hundreds of brown algae such as giant kelp, kelp, fucus and sargassum. Among them, the content in Laminariaceae algae is relatively high (about 20% on average), and most of them exist in the form of calcium salts and magnesium salts.
