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.
It's 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 pharmacy and health and beauty food.
