Sodium hyaluronate is widely exists in placenta, amniotic fluid, lens, articular cartilage, skin dermis and other tissues. In organs, it is distributed in the cytoplasm and intercellular substance, which can lubricate and nourish the cells and organs, and provide the microenvironment for cell metabolism. Moisturizing effect is the most important role of sodium hyaluronate in cosmetics. Compared with other moisturizers, the relative humidity of the surrounding environment has less influence on its moisturizing properties.Product name:

Sodium Hyaluronate

Molecular Formula:

C14H22NNaO11

Molecular Weight:

799.638

CAS No.:

9067-32-7

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.
