Introduction
Pharmaceutical-grade sodium hyaluronate (HA) is a cornerstone of modern medical and cosmetic formulations, prized for its unparalleled biocompatibility, viscoelasticity, and hydration properties. As a high-purity polymer, its performance hinges on precise control of molecular weight (MW) and concentration, which directly influence functionality in applications ranging from injectable dermal fillers to ophthalmic surgical aids. At Runxin Biotech, we specialize in delivering pharmaceutical-grade HA powder tailored to meet rigorous pharmacopeial standards (EP/USP), empowering innovators to develop advanced therapeutic and aesthetic solutions.
The molecular weight of HA determines its physicochemical behavior and biological interactions:
Low MW (10–50 kDa)
Subcutaneous formulations for wound healing.
Intra-articular injections for osteoarthritis management.
Properties: High tissue permeability, anti-inflammatory, and pro-angiogenic effects.
Applications:
Formulation Tip: Use at 0.1–0.3% w/v combined with mid-MW HA to balance penetration and residence time.
Mid MW (100–500 kDa)
Topical gels for post-surgical scar modulation.
Nasal sprays for mucosal hydration.
Properties: Optimal balance of viscosity and bioactivity.
Applications:
Formulation Tip: Ideal at 0.5–1.2% w/v for sustained release in semi-solid matrices.
High MW (1,000–3,000 kDa)
Dermal fillers for facial volumizing.
Ophthalmic viscosurgical devices (OVDs) for cataract surgery.
Properties: Superior viscoelasticity, lubrication, and space-filling capacity.
Applications:
Formulation Tip: Use at 1.0–2.5% w/v in crosslinked or non-crosslinked systems for long-lasting effects.
| Application | Recommended Concentration | Rationale |
|---|---|---|
| Injectable Dermal Fillers | 1.8–2.4% w/v | Ensures mechanical stability and natural feel. |
| Ophthalmic Viscosurgical Devices | 1.0–1.5% w/v | Balances flow properties and corneal protection. |
| Topical Wound Dressings | 0.5–1.0% w/v | Enhances moisture retention without impeding gas exchange. |
| Intra-articular Injections | 0.8–1.2% w/v | Optimizes synovial fluid supplementation. |
