General Description
Sodium Hyaluronate is linear high molecular weight mucopolysaccharide composed by thousands of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-glucosamine. Sodium hyaluronate is so water-friendly and it has functions of the best moisturizing factor and prevents diseases such as skin infections by preventing the penetration of external substances such as bacteria. Therefore, it is regarded as an ideal “natural moisturizer” factor and widely used in cosmetics that suitable for different skins, climates and environments.
