Sodium Hyaluronate (hyaluronic Acid, HA), the sodium salt of hyaluronic acid ,is a linear high molecular weight mucopolysaccharide compose by thousands of repeating disaccharide units of D-glucuronic acid and N-acetyl-D-glucosamine.
Advantages:
1.High safety
2.High purity
3.Professional Service
Customerized products
All-around technical support for HA application in cosmetic
3. Functions
The molecular weight of HA is 1 kDa-3,000kDa. HA with different molecular weight has different function in cosmitics.
Tapes | Molecular weight | Functions |
HA | ≥ 1,000kDa | Lubricating and film-forming, moisturizing, preventing skin damage, thickening and keeping emulsion stable |
Low molecular weight HA | 10kDa~1,000kDa | Nourishing the skin, long lasting moisturizing |
Oligo HA | < 10kDa | Trans-dermal absorption, deep hydrating, anti-ageing, repairing skin damage |
