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.

Brief Introduction
Fluorescent brightener is a substance that can absorb ultraviolet rays from sunlight or other light sources and emit blue to purple fluorescence, so that materials can produce whitening and luster effects. It is also called optical whitening agent because it uses the optical complementary color function to make the dark matter appear white and bright after fluorescent whitening.
