Molecular Formula: (C₁₄H₂₁NO₁₁)n
CAS Number: 9004-61-9

Key Features:
1.Dual Molecular Weight Options:
1.1High Molecular Weight (1.3–1.5 MDa): Forms a breathable protective film on the skin surface, locks in moisture, smooths skin texture, and prevents damage from external stressors such as dust and UV radiation.
1.2.Low Molecular Weight (200–400 kDa): Penetrates deeper layers of the skin to promote nutrient absorption, improve elasticity, reduce fine lines and wrinkles, and delay signs of skin aging.

2.Excellent Compatibility:HA-Sol is highly compatible with various cosmetic ingredients, including glycerin, surfactants, peptides, and bioactive compounds, allowing flexible formulation in serums, lotions, creams, masks, sprays, and other personal care products.

3.High Purity and Safety:Produced in ISO9001, HACCP, GMP-certified facilities with ISO14001 environmental management system. Sodium hyaluronate content is stable at 97–99%, glucuronic acid ≥46%, protein ≤0.05%, and endotoxin levels as low as 0.07 EU/mg. Heavy metals and other impurities are strictly controlled, ensuring high product safety for cosmetic, pharmaceutical, and functional food applications.

4.Stable and Reliable:Viscosity remains consistent across batches, with no significant reduction after standing 3–5 days under normal conditions. The solution is clear, color-stable, and demonstrates excellent hydrolytic stability, ensuring long-lasting performance in formulations. pH is maintained at 6–7, avoiding irritation or sensitization.
