HA is a straight chain macromolecular mucopolysaccharide composed of repeat disaccharide units of glucuronic acid and acetylglucosamin. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc.The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million. It's aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food. Specific advantages: (1) High purification of more than *9%, and D-glucuronic acid of more than *7%. (2) Classified in different molecular weights to meet customers various requirements. (3) Protein content is very low thus hypersensitivity is prevented. (4) No antiseptic and thickening agent. Hazardous chemicals aren't allowed to be used during production. (5) Key equipments and raw materials are imported. All materials are non-animal and uncertain infection from animals is avoided. (6) High safety as no bacteria is detected. (7) Its solution is of high transparency of more than *9%
