Molecular Formula:C28H44N2O23
Hyaluronic Acid Sodium Salt
Brief Introduction
Hyaluronic acid is an acidic mucopolysaccharide. With its unique molecular structure and physicochemical properties, hyaluronic acid shows a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of vascular wall, regulating protein, water and electricity, chemical Book solute diffusion and operation, promoting wound healing and so on. Especially important, hyaluronic acid has a special water retention effect. It is the best moisturizing substance found in nature. It is called an ideal natural moisturizing factor.

Molecular Formula:C28H42N2Na2O23
Hyaluronesodium; Hyaluronic Acid Sodium Salt
Brief Introduction
Sodium hyaluronate is a kind of physiological active substance widely existing in human body. It is a kind of high molecular weight straight chain mucopolysaccharide polymerized by disaccharide unit composed of glucuronic acid and acetaminohexose. It forms a kind of thick viscoelastic solution in water with physiological pH and ionic strength. Its molecular form is variable, so it can be passed through with a thinner injection needle. The substance that does not produce inflammation in sodium hyaluronate is extracted, which is called Healon. Sodium hyaluronate can promote wound healing. Sodium hyaluronate can form a macromolecular network barrier on the surface of eye tissue, prevent inflammatory substances from entering the wound and lesion area, and can significantly improve the viscosity and adhesion of the drug solution, so that the drug can remain on the corneal surface for a long time and intensively, achieving a long-term and powerful effect. Sodium hyaluronate can stabilize the tear film, prolong the tear film rupture time and relieve the symptoms of dry eyes. It is used for corneal burns caused by keratitis, corneal ulcer, corneal injury or other chemical and physical factors. Therefore, sodium hyaluronate is widely used in high-end cosmetics industry, as well as in the treatment of dry eye syndrome.
