High Quality Sodium Hyaluronate Eyedrop Grade
Introduction:
Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed of repeat disaccharide units of glucuronic acid and N-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.
