Product Overview

Sodium Hyaluronate Medium Molecular Weight (INCI: Sodium Hyaluronate, CAS 9067-32-7, MW 1,000-1,500 kDa) occupies the versatility sweet spot between high MW (1,500-2,000 kDa, surface film-forming only) and low MW (400-1,000 kDa, deep epidermal penetration) HA grades. At 1.0-1.5 million Daltons, the polymer chains are long enough to provide effective surface film-forming, moisture retention, and moderate viscosity building (0.3-0.8% w/w produces elegant, non-stringy texture), yet small enough to enable partial penetration into the upper epidermis (stratum corneum through stratum granulosum) via the intercellular lipid pathway — delivering sustained sub-surface hydration that pure surface-film HA grades cannot achieve. This dual-action performance — immediate surface moisturization via film-forming + extended sub-surface hydration via partial epidermal penetration — makes medium MW HA the most adaptable single HA grade. It can serve as a standalone humectant in formulations where balanced performance is preferred over extreme specialization, or as the central component in multi-MW HA blends (with high MW for added surface film and low MW for deeper penetration). The moderate viscosity and smooth sensory profile (no stringiness or tackiness characteristic of high MW HA at equivalent concentrations) make it particularly well-suited for light-textured formulations — serums, essences, lotions, BB/CC creams — where consumer-preferred rapid absorption and silky after-feel are critical. In food and nutraceutical applications, medium MW HA is used as a premium dietary supplement ingredient supporting joint health (synovial fluid viscoelasticity) and beauty-from-within (skin hydration from oral supplementation). UPOR Biotech manufactures under c-GMP and ISO 9001:2015 with COSMOS natural certification and full regulatory documentation.

As a specialized HA manufacturer and bulk supplier, UPOR Biotech provides medium MW sodium hyaluronate for B2B cosmetic brands, contract manufacturers, and nutraceutical companies. OEM formulations available. Free sample for qualified B2B buyers.

Medium MW HA — The Versatile All-Rounder

High MW HA (1,500-2,000 kDa) is a heavy surface film-former — excellent for rich creams but limited to stratum corneum hydration only. Low MW HA (400-1,000 kDa) penetrates deep into the epidermis for anti-aging — ideal for serums but provides minimal surface film. Medium MW HA (1,000-1,500 kDa) bridges both worlds: enough chain length for effective surface film-forming and moisture retention, plus sufficient chain flexibility for partial upper-epidermis penetration delivering sustained sub-surface hydration. It is the most adaptable HA grade — a single-ingredient solution for light creams, lotions, essences, BB creams, and all-purpose moisturizers where balanced, versatile performance matters more than extreme specialization at either end of the MW spectrum.

Key Benefits — Medium MW Sodium Hyaluronate

Balanced Dual-Action Performance

Occupies the optimal middle ground: surface film-forming for immediate moisturization + partial upper-epidermis penetration for sustained sub-surface hydration. A true dual-action humectant — versatile standalone or central component in multi-MW HA blends.

Balanced MW

Smooth, Elegant Texture — Moderate Thickening

At 0.3-0.8% w/w, delivers smooth, non-stringy viscosity without the heavy gel character of high MW HA. Ideal for light creams, lotions, and serums where rapid absorption and silky after-feel are consumer priorities.

Smooth Texture

Extended Hydration — Surface + Sub-Surface

The mid-range MW enables partial intercellular lipid pathway penetration into the upper epidermis (SC through stratum granulosum) while retaining enough surface film for lasting moisturization — dual-level hydration from a single HA grade.

Dual Action

Certified Quality — Cosmetic and Food Grade

c-GMP (ICH Q7) manufacturing, USP/EP compliant, COSMOS Natural Certified, HALAL, KOSHER. Full documentation: COA, MSDS, TSE/BSE statement, stability data, lot traceability. Suitable for cosmetic and dietary supplement applications.

Applications

Light Creams and Lotions — Balanced Moisturization

Ideal mid-range thickener and moisturizer for fluid creams, body lotions, and daily moisturizers at 0.3-0.8%. Silky, non-greasy finish with smooth spreading and quick absorption.

Hydrating Serums and Essences — Fast-Absorbing

Lightweight, fast-absorbing texture perfect for water-based and emulsion serums. Delivers balanced surface and sub-surface hydration without the heaviness of high MW HA.

Frequently Asked Questions

Medium MW HA (1,000-1,500 kDa) is a versatile all-rounder for light creams, lotions, serums, BB creams, foundations, body care, and eye care. It provides balanced dual-action: moderate surface film-forming and thickening + upper-epidermis penetration for extended sub-surface hydration. In food applications, used as a dietary supplement for joint health and beauty-from-within.

Medium MW bridges both worlds. High MW (1,500-2,000 kDa) stays on the surface — best for rich creams needing heavy film-forming. Low MW (400-1,000 kDa) penetrates deeper for anti-wrinkle benefits — best for serums. Medium MW offers enough surface presence for moisturization plus partial epidermal penetration for sustained hydration. Many formulators use medium MW as standalone or blend all three MWs for comprehensive multi-level hydration.

ISO 9001:2015, c-GMP (ICH Q7), FDA-registered, HALAL, KOSHER, COSMOS Natural Certified. Meets USP and EP. Every shipment: COA, MSDS, TSE/BSE statement, stability data, complete lot traceability.

0.3-0.8% w/w in cosmetic formulations. At 0.3% — light moisturization with minimal viscosity impact. At 0.5-0.8% — noticeable texture enhancement and balanced hydration. Hydrates more readily than high MW HA (1-3 hours full hydration with gentle stirring). Compatible with most cosmetic ingredients.

15-25°C in a dry, dark place. Keep tightly sealed — sodium hyaluronate is hygroscopic. Shelf life 2-3 years under proper storage. Once dissolved in water, use within 24-48 hours or add appropriate preservatives. Avoid high humidity and direct sunlight.
