Cosmetics for Moisturizing Hyaluronic Acid Sodium Salt

Hyaluronic acid sodium salt (CAS No.: 9067-32-7) is the sodium salt of hyaluronic acid, a glycosaminoglycan found in various connective, epithelial, and neural tissues. Sodium hyaluronate, a long-chain polymer containing repeating disaccharide units of Na-glucuronate-N-acetylglucosamine, occurs naturally on the corneal endothelium, bound to specific receptors for which it has a high affinity. The polyanionic form, commonly referred to as hyaluronan, is a visco-elastic polymer normally found in the aqueous and vitreous humour.
