5. What is sodium hyaluronate?
Sodium hyaluronate, we often call it hyaluronic on the market. Hyaluronic acid is a glycosaminoglycan (a type of polysaccharide) which is present in all living organisms. It belongs to the most numerous group of compounds which have an identical chemical structure in both bacteria and human beings. Its name comes from the Greek word hyalos, meaning glass. Its colourless, translucent, and glassy as the name suggests. Hyaluronic acid present in the skin is one of its key components. The ability to bind water in the epidermis inhibits creation of wrinkles and makes skin elastic. What is more, it maintains water in the organism and the level of tissue fluid contained in the extracellular matrix. Hyaluronic acid protects skin against drying and enhances its defensive.

Applications
Dalton, referred to as Da., is a unit of sodium hyaluronate molecular weight. According to its molecular weight, Sodium Hyaluronate can be classified with the following classification:
High molecular weight: (MW between 1.5m~2.2m Da) can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage.
Middle Molecular weight: (MW between 1.0m~1.5m Da) can tighten the skin and keep skin moisturizing for long term.
Low Molecular Weight:(MW between 3000~100 000 Da) can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and so it has function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.
The molecular weight of Sodium Hyaluronate is very wide, ranging from tens of thousands to millions Dalton. Sodium Hyaluronate has different effect with different molecular weight. It is not more than 1.5 million generally when using in cosmetics.
The role of Sodium Hyaluronate in Cosmetics
1. Moisturizing effect
2. Skin repair effect
3. Skin nutrition and anti-winkles effect
4. Emollient and Film-forming
5. Creaming and Thickening
