Features
Reduced Formulation Interference
With 97.2% hyaluronic acid and 0.032% protein, it introduces few non-target components into the formulation, minimizing additional impact on the system.
Directly Enables High-Viscosity Systems
With a molecular weight of 1.20 × 10⁶ Da and intrinsic viscosity of 19.83 dL/g, it significantly increases viscosity in aqueous phases, making it suitable for gel construction or improving system consistency.
Suitable for Transparent Formulations
With 99.9% light transmittance and 0.10 absorbance, it does not cause turbidity or color changes in serums, gels, and other systems.
Wide Operating Conditions
With a pH range of 5.0–8.5 (measured at 6.5), it can be directly added to conventional aqueous systems without additional adjustments.
Applications
Skincare and Cosmetics: Used in serums, creams, and lotions as a basic moisturizing and film-forming component, influencing the skin's surface moisture retention.
Gels and High-Viscosity Products: Used in gel products as a primary structural source, participating in system viscosity formation.
Multi-Layer Moisturizing Formulas: Used in combination with low-molecular-weight or modified hyaluronic acid to construct different layers of moisturizing structure.
