As a manufacturer specializing in hyaluronic acid production, we provide cosmetic grade sodium hyaluronate covering the full molecular weight spectrum, from ≤10kDa oligo fractions for deep skin penetration to 2,500kDa high molecular weight variants for surface hydration and film-forming protection. All grades are produced in ISO and GMP certified facilities, with a minimum purity of 95%, and undergo strict controls for heavy metals and microorganisms. We offer comprehensive technical formulation support and flexible customization options, partnering with cosmetic brands worldwide to develop skincare products.
Type | Molecular Weight | Function |
|---|---|---|
High Molecular Weight Sodium Hyaluronate | 1800kDa – 2500kDa | Forms protective film, locks moisture |
Intermediate Molecular Weight Sodium Hyaluronate | 800kDa – 1500kDa | Balances hydration and absorption |
Low Molecular Weight Sodium Hyaluronate | 20kDa – 40kDa | Penetrates skin, improves elasticity |
Oligo Sodium Hyaluronate | ≤10kDa | Deep absorption, rapid hydration |
Formulators may select a single grade or combine multiple grades to achieve layered hydration effects, addressing both surface moisture retention and deep skin nourishment in a single product.

Sodium hyaluronate is widely incorporated into cream and lotion formulations. It supports skin moisture retention and contributes to improved skin smoothness, making it suitable for daily hydration-focused skincare products.
In facial mask products, sodium hyaluronate delivers targeted hydration during application. Different molecular weight grades can be selected to match the desired skin feel and penetration profile of mask formulations.
For lightweight serum formulations, lower molecular weight and oligo sodium hyaluronate are commonly used. These grades support skin absorption and contribute to improved skin elasticity with consistent application.
The ingredient is compatible with a range of personal care formulations, adding moisture-related benefits to both leave-on and rinse-off product types.
We support customization of molecular weight and particle size based on specific formulation requirements. Business buyers can request adjusted parameters to align with their product development goals.
Our technical team provides guidance for formulation development, assisting cosmetic brand clients in selecting appropriate sodium hyaluronate grades and optimizing ingredient incorporation processes.
Different molecular weights deliver different skin benefits. Oligo hyaluronic acid supports deep skin penetration, while high molecular weight variants provide surface-level hydration. Formulators may select single grades or combine multiple grades based on their product efficacy targets.
Yes, we offer full customization of molecular weight based on specific application requirements. Clients can consult with our team to define parameters that match their formulation needs.
Cosmetic grade sodium hyaluronate is used in skincare formulations around the world. Our products meet cosmetic grade quality standards, with controlled levels of heavy metals, microorganisms, and impurities to support skin compatibility.
