Core Advantages
High Purity & Pharmaceutical-Grade
Boasts high purity and low impurity residue, with strictly controlled endotoxin levels. This ensures safe application in ophthalmic formulation systems, meeting the quality requirements of artificial tears and post-operative care products.
Moisturizing & Lubricating
Forms a stable hydrating protective film on the ocular surface, effectively reducing tear evaporation and improving dryness, fatigue, and foreign body sensation, while enhancing long-term eye comfort.
Biocompatible & Low Irritation
Derived from microbial fermentation and contains no animal-derived components, resulting in higher safety. It is gentle and non-irritating to ocular tissues, suitable for long-term use and sensitive formulations.
Compatibility & Stability
Highly compatible with various eye drop systems and maintains stable performance in different pH and electrolyte environments, making it suitable for the development of single-dose and multi-dose ophthalmic products.
Production Process & Quality Control
1. Microbial Fermentation
Produced using a highly controlled fermentation system, avoiding animal-derived risks from the source and ensuring excellent raw material stability and batch-to-batch consistency.
2. Multi-stage Purification
Impurities are completely removed through ultrafiltration, nanofiltration, and deep deproteinization processes, vastly improving product purity and reducing immunogenicity risks.
3. GMP Standard Management
The entire process is controlled according to strict GMP principles, maintaining a fully traceable production system from initial fermentation to the finished product.
4. Complete Quality Documents
Each batch comes with a Certificate of Analysis (COA), MSDS (Material Safety Data Sheet), and pharmacopoeia compliance documentation to satisfy global regulatory requirements.
Application Areas
Artificial Tears Products
Acts as a core moisturizing ingredient to relieve dry eye symptoms, improve the ocular surface lubrication environment, and enhance daily eye comfort.
Post-Ophthalmic Care
Widely utilized in ocular surface repair formulations following cataract, corneal, and laser surgeries to help reduce irritation and accelerate recovery.
Corneal Protection & Repair
Applied in corneal protection preparations to reduce mechanical friction damage, maintain critical ocular surface moisture, and support barrier functions.
High-End Eye Care & Contact Lenses
Incorporated into premium eye care solutions and contact lens lubricants to significantly improve wearing comfort while reducing dryness and foreign body sensations.
