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 has aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food.     

Introduction of cosmetic grade Hyaluronic acid ( HA ) 

HA is a natural biotic component widely presents in skin and other tissues. It has outstanding moisturizing effect, thus called Natural Moisturizing Factor (NMF) in the world. HA is the best component used in cosmetics for moisturizing from the nature.
