Description  

Sodium Hyaluronate is a white or similar white powder. It is sparingly soluble in water, and practically insoluble in ethanol.

 

Application

(1) As a carrier for ophthalmic drugs, it prolongs the residence time of the drug on the surface of the eye by increasing the viscosity of the eye drops, improves the bioavailability of the drug, and reduces the irritation of the drug to the eye.

(2) Small molecule hyaluronic acid can penetrate into the dermis layer to promote blood microcirculation, which is beneficial to the absorption of nutrients by the skin and plays a health care role of beauty and anti-wrinkle.

(3) As a moisturizer in cosmetics. Compared with other moisturizer, the relative humidity of the surrounding environment has less influence on its moisture retention.
