Safe Injection Grade Sodium Hyaluronate Powder Low Bacterial Endotoxins

Hot Sell Injection Grade Sodium Hyaluronate White Powder With High Quality
 
Injectable grade sodium hyaluronate (SH) is the sodium salt form of hyaluronic acid (HA), a high molecular weight polysaccharide, and its chemical structure consists of D-glucuronic acid and N-acetylglucosamine alternately connected by β-1,3 and β-1,4 glycosidic bonds to form a stable double helix structure. Its aqueous solution has high viscoelasticity, biocompatibility and strong hydrophilicity, and can absorb 500-1000 times its own weight of water.
 
Core features
 

• Super strong water retention: 1 gram of hyaluronic acid can bind up to 1,000 times the water molecules to form a three-dimensional network structure to maintain tissue moisture and elasticity.
• Viscoelastic self-adaptation: Under dynamic stress (such as joint movement or facial expression changes), its viscosity can change with shear force, providing support while avoiding stiffness.
• Biocompatibility: Highly consistent with endogenous hyaluronic acid in the human body, the degradation products are water and carbon dioxide, and there is no residual toxicity.

 
Specifications
 

 
Production method
 

• Microbial fermentation method: mainstream process, using streptococcus fermentation to avoid animal-derived contamination risks.
• Purification steps: ultrafiltration to remove impurities, chromatography technology to reduce endotoxins, ensuring purity >95%.

 
Key points of quality control
 

• Molecular weight detection: Gel permeation chromatography (GPC) determination to ensure batch consistency.
• Safety tests: rabbit pyrogen test, cytotoxicity test, sensitization test, etc.
