Sodium Hyaluronate
The gold-standard hydrator for long-lasting skin moisture
INCI Name
Sodium Hyaluronate (Hyaluronic Acid)
CAS No.
9067-32-7
Appearance
White crystalline powder, odorless
Purity
95–100%
Overview
Function and skin care benefits
Sodium Hyaluronate is a highly effective moisturizing ingredient with excellent water-binding properties. It is widely used in skin care formulations to help maintain skin hydration and improve the overall appearance of skin.
Molecular Weight Options
Type | Molecular Weight | Typical Properties |
|---|---|---|
High Molecular Weight (HMW) | >1,000 kDa | Excellent film-forming and surface moisturizing properties |
Medium Molecular Weight (MMW) | 500–1,000 kDa | Balanced moisturizing and skin conditioning properties |
Low Molecular Weight (LMW) | 10–500 kDa | Suitable for advanced moisturizing formulations |
Ultra-Low Molecular Weight | <10 kDa | Used in high-performance skincare formulations |
Key benefits
Long-lasting hydration
Helps improve skin smoothness and softness
Helps maintain skin moisture levels
Helps improve the appearance of fine lines caused by dryness
Helps maintain a smooth and hydrated skin appearance
Efficacy evaluation
stratum corneum moisture vs. untreated control
In a hydration evaluation study, Sodium Hyaluronate significantly increased stratum corneum moisture levels. Compared with untreated skin, the Sodium Hyaluronate group achieved nearly 2.8-fold the moisture level of the control group, demonstrating its exceptional moisture-retention capability and ability to support long-lasting skin hydration.
Applications
Solubility
Soluble in water; gentle heating may accelerate hydration and dissolution.
Stability
Relatively stable within the pH range of 5–8 under recommended formulation conditions.
Typical applications
Serums / Essences / Toners / Facial masks / Eye care products / Moisturizing creams
Recommended usage level
0.1%–2.0% depending on grade
Formulation guidelines
Recommended Usage Level — HMW 0.1%–0.5%; MMW 0.1%–0.3%; LMW 0.2%–0.5%; Ultra-Low Molecular Weight 0.5%–2.0%.
Synergistic Hydration — Recommended to be used in combination with polyols (e.g., glycerin, glycols, betaine) to enhance moisturizing performance.
pH & Ionic Compatibility — Avoid direct mixing with strong acids (pH < 4), strong bases (pH > 11), or high-concentration cationic surfactants (such as quaternary ammonium salts) to prevent precipitation or loss of viscosity.
Electrolyte Sensitivity — High concentrations of added salts (e.g., NaCl) should be avoided, as electrolytes can cause the molecular chains to coil, leading to a significant decrease in viscosity. Electrolyte levels must be carefully controlled.
Temperature Control — Maintain processing temperatures below 60°C to prevent thermal degradation of the molecular chains caused by prolonged heating.
Dissolution & Handling — Sodium Hyaluronate is highly hygroscopic. It is recommended to fully hydrate and dissolve it in deionized water before adding other aqueous components. Maintain proper humidity control during handling and filling to protect product quality.
Stability ranges may vary depending on molecular weight grade, concentration, formulation matrix, and processing conditions. Final formulation stability should be confirmed through appropriate stability testing.
