Product Overview

Sodium Hyaluronate High Molecular Weight (1,500-2,000 K Da) is the largest molecular weight grade of hyaluronic acid sodium salt. With its exceptionally long polysaccharide chains, high MW HA forms a breathable, viscoelastic film on the skin surface, delivering powerful immediate surface hydration, superior thickening and rheology modification, and enhanced trans-epidermal water loss (TEWL) reduction. It is the most widely used hyaluronate grade for high-end cosmetic creams, serums, lotions, and facial masks.

In food applications, high MW sodium hyaluronate serves as a premium dietary supplement ingredient supporting joint lubrication and skin hydration from within. UPOR Biotech manufactures this product under strict c-GMP and ISO 9001 conditions with full lot traceability, COA, MSDS, and regulatory support documentation.

Key Benefits — High MW Sodium Hyaluronate

Superior Film-Forming

Forms a breathable, protective viscoelastic film on the skin surface that locks in moisture and shields against environmental aggressors. The exceptionally long polymer chains create a 3D network unmatched by lower MW grades.

TEWL Reduction

Excellent Thickening & Rheology

Provides outstanding viscosity build and gel texture at low concentrations (0.1-0.5%). Enhances product sensory properties — gives creams a rich, luxurious feel and excellent spreadability.

Texture Enhancement

Intense Surface Hydration

Binds up to 1,000 times its weight in water. Delivers immediate, visible skin plumping and smoothing on the skin surface. Ideal for “instant effect” cosmetic formulations.

1000x Water Binding

Certified Quality

Manufactured under strict c-GMP conditions with full lot traceability. USP/EP compliant. Complete regulatory documentation package (COA, MSDS, TSE/BSE statement, stability data) with every shipment.

Frequently Asked Questions

High MW sodium hyaluronate (1,500-2,000 K Da) is used as a film-forming moisturizer, thickener, and rheology modifier in cosmetic creams, serums, lotions, and masks. It stays on the skin surface, forming a protective, breathable barrier that reduces water loss. In food, it is used as a dietary supplement ingredient for joint health.

0.1-1.0% by weight, with 0.3-0.5% being the most common range. At 0.5%, high MW HA forms a viscous, film-forming gel. Due to its high molecular weight, it should be dispersed slowly with high-shear mixing and allowed to fully hydrate (typically 2-4 hours) for optimal viscosity development.

Our sodium hyaluronate is manufactured under ISO 9001:2015, c-GMP, FDA-registered, HALAL, KOSHER, and COSMOS-certified conditions. All products meet USP and EP standards. Full documentation (COA, MSDS, TSE/BSE, stability data) is provided with each shipment.

No — the large molecular size (1,500-2,000 K Da) prevents penetration beyond the stratum corneum. This is by design: high MW HA functions as a surface film-former and moisturizer. For deeper penetration, we recommend our lower molecular weight grades (see comparison table above). Many formulators combine high MW HA (surface film) with low MW HA (deeper delivery) for comprehensive multi-level hydration.

Store at 15-25°C in a dry, dark place. Keep containers sealed to prevent moisture absorption (HA is hygroscopic). Shelf life is 2-3 years under proper storage conditions. Once dissolved in water, use within 24-48 hours or add appropriate preservatives.
