Product Description
Sodium Hyaluronate Molecular Weight Grades CAS 9067-32-7
Product Overview

Sodium Hyaluronate is available in a range of molecular weight grades that dramatically influence its functional performance in cosmetic and medical formulations. This product line encompasses Low Molecular Weight (LMW: 10-100 kDa), Medium Molecular Weight (MMW: 500-1000 kDa), and High Molecular Weight (HMW: 1.5-3.0 MDa) Sodium Hyaluronate, each engineered to deliver distinct rheological and biological properties. Selecting the correct molecular weight is critical for achieving target formulation viscosity, skin penetration depth, and moisturization longevity.

Key Benefits
  • Tailored Viscosity Control: HMW grades provide superior thickening and film-forming for long-lasting hydration, while LMW grades penetrate deeper into the epidermis for intracellular moisture replenishment.
  • Versatile Formulation Windows: Compatible with oil-in-water, water-in-oil, and gel-based systems across pH 4.0-8.0, making it an indispensable humectant for diverse product types.
  • Enhanced Bioavailability: Our MMW fractions display optimal balance between dermal absorption and surface retention, ideal for daily-wear serums and essences.
  • Batch-to-Batch Consistency: Tight molecular weight distribution control (PDI ≤ 1.5) ensures reproducible formulation performance across production cycles.
  • Multi-Source Fermentation: Produced via Streptococcus zooepidemicus fermentation with solvent-free purification, meeting ECOCERT and COSMOS natural ingredient standards.

Application Areas by Grade
LMW Grade Applications
  • Anti-Aging Serums: Penetrates stratum corneum to deliver hydration directly to viable epidermis; stimulates endogenous HA production in fibroblasts.
  • Eye Contour Treatments: Low viscosity allows precise application around delicate periorbital area without dragging.
  • Acne-Prone Formulations: Non-comedogenic profile at low molecular weight; regulates sebum without occlusive effects.
  • After-Sun Repair: Rapid penetration to soothe UV-stressed keratinocytes and restore NMF (Natural Moisturizing Factor).
HMW Grade Applications
  • Overnight Sleeping Masks: Forms a breathable hydrating film that locks in actives for 8+ hours of continuous moisturization.
  • Sunscreen Vehicles: Enhances spreadability and water-resistance of UV filters while providing non-greasy skin feel.
  • Hair Conditioners and Leave-In Treatments: Deposits a weightless moisture-binding layer on hair cuticles, reducing frizz by up to 40%.
  • Post-Procedure Care: Creates a protective microenvironment over micro-injured skin following chemical peels or laser treatments.
Manufacturing Process

Our Sodium Hyaluronate is manufactured through a controlled bio-fermentation process: (1) Streptococcus zooepidemicus is cultured under strict aseptic conditions in glucose-rich media; (2) the fermentation broth undergoes ethanol precipitation to isolate crude Sodium Hyaluronate; (3) enzymatic hydrolysis precisely controls molecular weight reduction when targeting LMW/MMW grades; (4) multi-stage membrane filtration (0.22 μm terminal sterilization) removes bacterial endotoxins; (5) spray-drying yields a free-flowing powder with residual moisture ≤ 10%. Every batch is tested for molecular weight distribution via Gel Permeation Chromatography (GPC) and endotoxin levels via LAL assay (≤ 0.5 EU/mg).

Why Choose Our Molecular Weight Grade Sodium Hyaluronate
  • Triple-Grade Portfolio: Unlike suppliers offering single-grade Sodium Hyaluronate, we provide all three molecular weight ranges from one source, simplifying supply chain management.
  • GPC-Verified Distribution: Each batch ships with a Gel Permeation Chromatography report showing the complete molecular weight distribution curve—not just a single viscosity value.
  • Endotoxin-Controlled: LAL-tested to ≤ 0.5 EU/mg, meeting the stringent requirements for ophthalmic and injectable-grade applications.
  • Technical Formulation Support: Our applications lab provides viscosity-building curves at 0.1%-2.0% concentration for each grade to guide your formulation development.
Frequently Asked Questions
Which molecular weight grade should I choose for a lightweight daily serum?
For a lightweight, fast-absorbing daily serum, we recommend our LMW grade (10-100 kDa). It provides deep hydration without surface tackiness and is compatible with pump-dispenser packaging due to its low solution viscosity.
What is the difference between cosmetic-grade and injection-grade Sodium Hyaluronate?
Injection-grade Sodium Hyaluronate requires endotoxin levels ≤ 0.05 EU/mg, higher purity (≥ 99%), and sterile processing. Our product is cosmetic-grade (endotoxin ≤ 0.5 EU/mg) and is suitable for topical formulations only. For injectable applications, please inquire about our medical-grade portfolio.
How does molecular weight affect skin feel in a formula?
HMW Sodium Hyaluronate creates a smooth, velvety after-feel with slight film formation. LMW grades absorb quickly with a light, water-like finish. Many formulators blend two or three grades at specific ratios to achieve a customized sensory profile.
What is the recommended usage level in cosmetic formulations?
Typical use levels are 0.1%-0.5% for HMW grades (serums, creams), 0.05%-0.2% for LMW grades (toners, mists), and 0.1%-1.0% for MMW grades (essences, masks). Higher concentrations may cause pilling in leave-on products.
Can different molecular weight grades be blended in a single formulation?
Yes. A popular strategy is to combine 0.1% HMW + 0.05% LMW Sodium Hyaluronate for both surface film hydration and deep penetration. We can provide pre-blended grades or separate components for your own blending.
