Description
Sodium hyaluronate is used to be called as hyaluronic acid. It is a water-soluble salt form of hyaluronic acid to
increase stability and lessen the likelihood of oxidization. It is a glycosaminoglycan and long-chain polymer
of disaccharide units of Na-glucuronate-N-acetylglucosamine.
Chemical Properties
INCI name: Sodium hyaluronate/ Hyaluronic Acid

Molecular Weight: (403.31)n
As a natural moisturizing factor , Sodium hyaluronate can be applied to many cosmetics products, such as cream, emulsion, astringent, serum, facial mask, etc. HA in cosmetics have different functions according to its different dosage and molecular weight.
| HA with different M.W | Recommended M.W Range | Efficiency |
| High M.W | >2000kDa
1500kDa~2000kDa |
High water retention，promote the regeneration of the cell tissue. |
| Ordinary M.W | 800kDa~1500kDa | Keep skin moisture and lubrication for a long time. |
| Low M.W | 100kDa~800kDa
10kDa~100kDa 8kDa~50kDa |
easily absorbed by skin, increase skin nutrition |
| Super low M.W. | 3kDa~10kDa | Trans-dermal absorption, deep hydrating |
