Hyaluronic acid (HA) is a straight-chain macromolecular mucopolysaccharide composed of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists of the extracellular space of the human and animal tissue, vitreum, umbilical cord, skin joints synovia, and cockscomb, etc. Commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid.
Now hyaluronic acid is used in microbial fermentation
HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million.
Hyaluronic acid is also one of the components of the dermis in the human body, have the ability to maintain moisture, and weigh up to 100 times its own weight, higher use with hyaluronic acid HA maintains the article, can improve dryness and wrinkled skin, make it restore the original smooth and elastic
Its aqueous solution has outstanding moisture-keeping ability, high viscoelasticity, and lubricity. It is widely used in cosmetics, Like l ‘oreal, Shiseido, and other well-known brands. It is also used in cosmetics pharmacies and health and beauty food.
