1. Basic Information
Name: Sodium hyaluronate
Alias: Sodium hyaluronan, HA sodium salt
CAS No.: 9067-32-7
Repeating unit molecular formula: C14H20N1O11Na1
Molecular weight: Variable, ranging from thousands to millions, determined by molecular weight grade
2. Physical and Chemical Properties
Physical Properties
- Appearance: White fibrous powder or fine powder
- Odor: Odorless
- Solubility: Fully soluble in water to form highly viscous transparent gel; insoluble in ethanol, acetone, ether and other organic solvents
- Hygroscopicity: Extremely strong hygroscopicity, quickly absorbs moisture in air to agglomerate
- Aqueous property: Neutral weak viscous aqueous solution, good lubricity and film-forming property
- Viscosity characteristic: Viscosity drops sharply under high temperature, strong acid, strong alkali and high shear force
Chemical Properties
- Molecular structure: Linear polysaccharide sodium salt polymer, alternately composed of D-glucuronic acid and N-acetyl-D-glucosamine disaccharide repeating units
- Acid-base stability: Stable under neutral and weak acid conditions; glycosidic bond hydrolyzes under strong acid/strong alkali heating to reduce molecular weight
- Enzymatic degradation: Hyaluronidase can break molecular chain and degrade viscosity
- Thermal stability: Stable below 40°C; long-term heating above 80°C causes molecular chain breakage and viscosity decline
- Photostability: Sensitive to ultraviolet light; long-term light irradiation accelerates degradation and discoloration
- Compatibility: Compatible with most cosmetic, food and pharmaceutical water-soluble raw materials; incompatible with high-concentration alcohol, strong oxidants, heavy metal ions
3. Main Application Fields
1. Cosmetic Raw Material (Core Application)
- High-efficiency humectant for essence, facial cream, mask, eye care products, forms water-locking protective film on skin surface

Safety Warning
Low-toxicity biological macromolecule raw material. Dust inhalation irritates nasal mucosa and eyes; avoid direct inhalation of fine powder. Wear dust mask and chemical-resistant gloves during operation. Must be completely sealed to prevent deliquescence and molecular weight degradation. Avoid long-term high temperature and light exposure. Waste can be treated as general biodegradable organic waste.
