Benzalkonium Chloride (BKC) is a widely recognized and extensively used preservative in the pharmaceutical industry, particularly within ophthalmic formulations. Its potent antimicrobial properties are crucial for maintaining the sterility and safety of eye drops and other ocular preparations throughout their shelf life. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier of high-quality Benzalkonium Chloride, understands the critical requirements for its use in sensitive ophthalmic applications.

The primary role of BKC in ophthalmic solutions is to prevent microbial contamination. Eye preparations, especially multi-dose containers, are susceptible to microbial introduction during use. BKC's broad-spectrum activity against bacteria, fungi, and viruses effectively eliminates any introduced microorganisms, thereby protecting the patient’s eyes from infection. Typical concentrations of BKC in ophthalmic products range from 0.004% to 0.02%, a level that balances antimicrobial efficacy with a minimized risk of ocular irritation.

Beyond its preservative function, BKC also possesses surfactant properties that can enhance the penetration of active pharmaceutical ingredients (APIs) into ocular tissues. This can be advantageous in formulations designed for specific therapeutic outcomes. However, it is also important to note that at higher concentrations or with prolonged exposure, BKC can cause ocular surface toxicity. This underscores the importance of using BKC at optimized concentrations and sourcing it from manufacturers who guarantee consistent purity and quality.
