Sodium Hyaluronate
Sodium hyaluronate, the sodium salt of hyaluronic acid, is a glycosaminoglycan found extensively in various connective tissues of humans. It is a long-chain polymer of disaccharide units of Na-glucuronate-N-acetylglucosamine, capable of binding to specific receptors with high affinity. The polyanionic form, known as hyaluronan, is a viscoelastic polymer present in the aqueous and vitreous humour of the eye and in the synovial fluid of joints.

Effects in Cosmetics
Serving as a tissue lubricant, sodium hyaluronate plays an important role in skincare products, helping to modulate interactions between adjacent tissues.
Forms a viscoelastic solution in water, providing mechanical protection by absorbing mechanical stress and offering a protective buffer for tissues.
In promoting wound healing, it acts as a protective transport vehicle, delivering peptide growth factors and other structural proteins to the site of action, then being enzymatically degraded to release active proteins to promote tissue repair.
Source
Sodium hyaluronate is obtained by reacting hyaluronic acid with sodium hydroxide.
