Alginic acid is a natural polysaccharide extracted from kelp, which is a mixture of the following two uronicacids. The product is a light yellow powder, odorless and almost odorless, insoluble in water, methanol, ethanol, acetone, chloroform, and soluble in alkaline solutions.
Uses
Medicine: The main raw material for producing gaiweiping, a tablet disintegrant; the new drug pss formulation has strong dispersibility and emulsifying properties.
Food: It can combine with various ions to form a series of alginate products, used in the production of health food and health food additives, such as sodium alginate, potassium alginate, calcium alginate, etc.
Environmental protection: Utiliz its adsorption properties for wastewater purification and treatment.
Executive standards: National Standard WS1-211-87, British Pharmacopoeia BP2007, and US pharmacopoeia USF30.
Introduction To Raw Materials
