Calcium Alginate
CAS NO.: 9005-35-0 Molecular Formula: (C12H14CaO12)n Molecular weight: 1170.93 Property: Calcium alginate is the Calcium salt of alginic acid, which is a natural carbohydrate extracted from kelp. Calcium alginate is made during the calcium alginate process for making sodium alginate; can be removed at the appropriate stage and, after thorough washing, can be dried and milled to a required particle size. Calcium Alginate is white to yellowish powder. It is odorless and tasteless, insoluble in water and most organical solvent, hardly soluble in ethyl alcohol, slowly dissolve in solution of sodium polyphosphate, sodium carbonate and calcium compound. Alginate is present in the cell walls of brown algae as the calcium, magnesium and sodium salts of alginic acid. Alginate molecules are long chains that contain two different acidic components, guluronic acid and mannuronic acid. The way in which these M and G units are arranged in the chain and the overall ratio, M/G, of the two units in a chain can vary from one species of seaweed to another. Usage: As a natural extraction from kelp, Calcium Alginate is widely used in food and pharmaceutical industry. In the feild of pharmaceuticals, calcium alginate is used as dressing to stop bleeding and accelerate wound healing. It can also be used on health food industry as a Calcium additive. Sometime, Calcium Alginate could be used as plasticizer of welding rod. Packake and Storage: 25Kg (Net weight) per bag, with compound package bag (a polyethylene bag as liner and a compound plastic woven bag as the outer layer)
