Application
1. Artificial Tears and Lubricating Eye Drops: Eye drop-grade sodium hyaluronate possesses excellent water-retention and viscoelastic properties, forming a stable hydration protective layer on the ocular surface to help maintain tear film stability. It is commonly used in artificial tears and lubricating eye drops to relieve dry eye and discomfort.
2. Ocular Surface Protection and Repair Formulations: Sodium hyaluronate exhibits good biocompatibility with ocular surface tissues, providing lubrication and protection, reducing blinking friction, and aiding in the stabilization of the ocular surface environment and the repair of minor damage. It is suitable for ocular surface care and postoperative care formulations.
3. Drug Delivery and Formulation Performance Optimization: Due to its excellent adhesion and rheological properties, eye drop-grade sodium hyaluronate helps prolong the residence time of formulations on the ocular surface, enhancing the persistence of action of active ingredients and improving the comfort of eye drops.
4. Preservative-free or low-irritant ophthalmic systems: Eye drop grade sodium hyaluronate is suitable for preservative-free or low-irritant ophthalmic formulations and can be used in single-dose or multi-dose formulations to meet the safety requirements of long-term or high-frequency use and people with sensitive eyes.
