Hyaluronic Acid (MMW)

Medium Molecular Weight Hyaluronic Acid

Supports sustained hydration, skin smoothness, and improved moisture distribution within cosmetic formulations.

INCI Name: Sodium Hyaluronate

Molecular Weight: 100–300 kDa 

Appearance: White to off-white powder

Solubility: Water soluble

Function: Humectant, skin-conditioning agent

Medium Molecular Weight Sodium Hyaluronate offers a balance between surface hydration and more uniform moisture distribution, making it well suited for daily-use cosmetic formulations where hydration longevity and skin feel are key.

What It Does

Medium Molecular Weight Sodium Hyaluronate is commonly used in cosmetic formulations to provide effective hydration while maintaining a smooth, lightweight skin feel. Its molecular size allows it to distribute moisture more evenly compared to high molecular weight grades.

This grade is often selected for formulations targeting improved skin texture, comfort, and hydration balance without excessive surface film formation.

Key Benefits

• Supports sustained skin hydration
• Helps improve skin smoothness and softness
• Balances moisture distribution within the skin surface
• Provides a lightweight, non-sticky feel
• Suitable for daily-use skincare products

Suggested Use Level

• Typical use: 0.05–0.3%

How to Incorporate

• Dissolve gradually into cold or room-temperature water.
• Mix until fully hydrated and uniform.
• Can be added during the water phase or pre-hydrated before formulation.

Formulation Notes

• Hydrates faster than high molecular weight grades.
• Compatible with most water-based cosmetic systems.
• Can be combined with high or low molecular weight hyaluronic acid for layered hydration systems.
