Application
Sodium Hyaluronate, a kind of mucopolysaccharides contains amino-sugar unit and uronic acid. It has physiological function of absorbing and retaining water to form jelly matrix for maintaining cell structure and protecting cell against bacterial infections. It is widely used in cosmetics and dermatologists for antiaging and moisturizing.
Packing In 25kgs net cardboard drum or as required.
