CAS number 9067-32-7
INCI name Sodium Hyaluronate
Low Molecular Hyaluronic Acid is a powerful hydrating ingredient commonly used in personal care and cosmetic products. As a water-soluble form of hyaluronic acid, it functions as a humectant, drawing moisture into the skin. It appears as a fibrous or cream-like powder and is often incorporated into face washes, makeup removers, and serums to enhance skin hydration and overall health.
Origin
Sodium Hyaluronate is derived from Hyaluronic Acid and is essentially its sodium salt. It is also known as hyaluronate sodium or hyalurone sodium. Hyaluronic Acid, from which it is extracted, is typically obtained through bacterial fermentation or from natural sources like animal tissues.
Purpose
Sodium Hyaluronate is widely used in skincare and cosmetics for its superior hydrating properties. It functions as a humectant, attracting and retaining moisture to improve skin hydration, elasticity, and overall health.

Smaller Molecular Size
Sodium Hyaluronate has a lower molecular weight than Hyaluronic Acid, allowing it to penetrate deeper into the skin. This makes it more effective at delivering moisture to the underlying layers, providing long-lasting hydration from within rather than just on the surface.
Superior Water Retention
One of its most remarkable properties is its ability to hold up to 1,000 times its weight in water. This intense moisture-binding capacity helps keep the skin plump, smooth, and well-hydrated, reducing dryness and dehydration-related fine lines.
Enhanced Stability
Unlike Hyaluronic Acid, which can be prone to degradation and oxidation, Sodium Hyaluronate is more stable in formulations. This ensures a longer shelf life and consistent performance in skincare and medical applications.
Fast Absorption
Due to its lightweight nature, Sodium Hyaluronate absorbs quickly into the skin without leaving behind a sticky or greasy residue. This makes it ideal for serums and lightweight skincare formulations that need to deliver hydration without heaviness.
Versatile Compatibility
It is highly compatible with a wide range of skincare products, including serums, creams, masks, and even medical formulations. Its ability to blend seamlessly with other active ingredients makes it a preferred choice in advanced skincare formulations.
Skin Barrier Support
Sodium Hyaluronate strengthens the skin’s natural protective barrier by reinforcing the lipid layer and reducing trans-epidermal water loss. This helps in keeping the skin resilient against environmental aggressors like pollution and harsh weather.
Soothing & Anti-Inflammatory
It has calming properties that help soothe irritated, red, or inflamed skin. This makes it beneficial for individuals with sensitive or reactive skin, including those dealing with conditions like rosacea or eczema.
Non-Comedogenic
Unlike some moisturizing ingredients that can clog pores and contribute to breakouts, Sodium Hyaluronate is non-comedogenic. This makes it suitable for all skin types, including oily and acne-prone skin, without causing congestion.
Bioavailability
Sodium Hyaluronate is more easily recognized and utilized by the skin than standard Hyaluronic Acid. Its improved bioavailability ensures that it delivers optimal hydration and skin benefits more efficiently.
Medical & Cosmetic Use
Beyond skincare, Sodium Hyaluronate is widely used in medical applications, such as ophthalmic solutions for dry eyes, dermal fillers for facial volume, and wound-healing treatments to promote tissue repair. Its multifunctionality makes it an essential ingredient in both beauty and healthcare industries.
