Overview of Selecting Sodium Hyaluronate Choosing sodium hyaluronate requires a 5-step framework: define application and regulatory target, select grade (food, cosmetic, pharmaceutical, injection), match molecular weight to function, set purity specifications, and evaluate supplier capability. Grade depends on exposure route, not purity alone. Molecular weight determines penetration, viscosity, and formulation behavior. Purity thresholds vary by risk level. Supplier assessment should cover testing methods, batch consistency, certifications, traceability, and documentation transparency.

Overview of Sodium Hyaluronate Purity Purity is a multi-dimensional profile, not one percentage. Key parameters: assay, glucuronic acid, protein, nucleic acids, endotoxin, heavy metals, solvents, and microbial limits, each with specific test methods. Criteria vary by grade: cosmetic requires protein ≤0.1%, assay ≥90%; pharma/injectable requires protein ≤0.05%, endotoxin ≤0.05 EU/mg. Impurities come from fermentation or extraction. Supplier evaluation should cover testing methods, batch consistency, certifications, traceability, and transparency.
