Product Features
Ultra-Low Endotoxin Control: Ophthalmic preparations have extremely high requirements for endotoxin levels. We employ industry-leading multi-stage ultrafiltration purification technology to control endotoxin levels far below pharmacopoeia requirements, fundamentally eliminating eye inflammation and rejection reactions.
Non-Animal Derivative (Microbial Fermentation): Sodium hyaluronate is produced through non-GMO streptococcal fermentation, completely avoiding the risk of animal-derived virus transmission and meeting the global market's dual demands for clean labeling and safety.
Excellent Biocompatibility and Biomimetic Rheology: Our sodium hyaluronate perfectly mimics the human natural tear film. It thins upon blinking (under shear force) to reduce foreign body sensation and thickens upon opening the eyes to prolong its residence time on the ocular surface, providing lasting lubrication.
High Stability and Tolerability: Sodium hyaluronate possesses excellent heat and shear stability, perfectly suited for aseptic filling processes in both single-dose (preservative-free) and multi-dose eye drops.
Core Applications
1. OTC Prescription and Non-Prescription Artificial Tears
Sodium hyaluronate effectively stabilizes the ocular tear film, reducing friction on the ocular surface and providing immediate and lasting relief for dry eye caused by prolonged computer use or dry environments.
2. Preservative-Free Single-Dose Eye Drops
Sodium hyaluronate is perfectly suited for advanced single-dose or multi-dose packaging with filter valves. The formula requires no added chemical preservatives, deeply protecting sensitive corneal epithelial cells.
3. Contact Lens Solutions and Lubricants
Sodium hyaluronate is a key additive in high-end multi-purpose contact lens solutions and lubricants, effectively improving lens water retention, prolonging wearing comfort, and reducing foreign body sensation.
4. Corneal Wound Healing and Postoperative Repair
After excimer laser surgery, cataract extraction, or corneal transplantation, sodium hyaluronate promotes epithelial cell migration in micro-wounds of the cornea, accelerating postoperative ocular surface repair.
Frequently Asked Questions
Q1: As a Chinese supplier, what international registration and compliance documents can you provide?
We have a comprehensive quality management system and can fully cooperate with global pharmaceutical companies in their registration applications. We can provide: GMP certificates, COA, MSDS, etc.
Q2: What are the storage conditions for pharmaceutical-grade sodium hyaluronate?
To prevent molecular weight degradation during long-term storage, we recommend storing the raw material in a refrigerated environment at 2–8°C and keeping the packaging sealed.
Q3: What is the minimum order quantity (MOQ) for ophthalmic grade? Can you provide samples?
For pharmaceutical-grade eye drop raw materials, our standard commercial MOQ is 100 grams. However, we fully understand the needs of pharmaceutical companies in the R&D and formulation testing stages, therefore we can provide 5-10 gram samples for your laboratory to conduct preliminary feasibility assessments.
