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.

Function:

1, Improving joint function

2, Natural moisturizing lubricant

3,It can prevent arteriosclerosis, pulse disorder and the occurrence of the disease such as the brain atrophy.

4.It is widely used in cosmetics 5.moisture retain 6.anti-ageing, lotion,cream
