Hyaluronic Acid (High Molecular Weight)

High Molecular Weight Hyaluronic Acid

Film-forming humectant to support surface hydration, moisture retention, and skin comfort

INCI Name: Sodium Hyaluronate

Molecular Weight: 800–1500 kDa 

Appearance: White to off-white powder

Solubility: Water soluble 

Function: Humectant, film former, skin-conditioning agent

High Molecular Weight Sodium Hyaluronate forms a lightweight, breathable hydrating film on the skin surface, helping to improve moisture retention and skin feel without penetrating into deeper layers.

What It Does

High Molecular Weight Sodium Hyaluronate is widely used in cosmetic formulations to provide immediate surface hydration and improve moisture retention through film formation on the skin.

Due to its larger molecular size, this grade remains primarily on the skin surface, making it suitable for formulations focused on skin comfort, smoothness, and barrier support rather than deep penetration.

Key Benefits

• Supports surface hydration and moisture retention
• Forms a breathable, non-occlusive hydrating film
• Improves skin smoothness and comfort
• Helps reduce visible dryness
• Suitable for sensitive-skin and barrier-focused formulas

Suggested Use Level

• Typical use: 0.05–0.5%

How to Incorporate

• Slowly disperse into cold or room-temperature water.
• Allow sufficient hydration time (several hours recommended).
• Mix gently to avoid aeration.

Formulation Notes

• Hydrates slowly; avoid high heat.
• Compatible with most water-based cosmetic systems.
• May be combined with low molecular weight hyaluronic acid for multi-level hydration concepts.

Common Applications

• Hydrating serums and gels
• Moisturizers and emulsions
• Toners and essences
• Soothing and barrier-support formulas
