NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that achieving the full benefits of Polyhexamethylene Biguanide Hydrochloride (PHMB) hinges on understanding and applying the correct dosage. While PHMB is known for its broad-spectrum antimicrobial activity and low toxicity, optimal performance and safety are directly linked to its concentration in specific applications. This guide outlines general dosage considerations for various uses of PHMB.

For general disinfection purposes, such as in industrial or institutional settings, the recommended PHMB disinfectant dosage typically ranges from 100 mg/L to 500 mg/L (or 0.01% to 0.05% active ingredient). This dosage is effective against a wide range of bacteria and fungi, providing a reliable sanitation solution for surfaces, equipment, and water systems. The exact concentration may need to be adjusted based on factors like the level of microbial contamination and the specific surface being treated.

In the textile industry, where PHMB antimicrobial finishing is applied, the dosage is determined by the desired level of protection and the application method. Manufacturers often use specific impregnation or dip-coating techniques with calibrated PHMB concentrations to ensure even distribution and long-lasting efficacy after washing. The goal is to achieve sufficient binding to the fibers to withstand multiple laundry cycles.

For contact lens solutions, the dosage of PHMB is strictly regulated to ensure ocular safety. Typically, concentrations are maintained at very low levels, often around 0.1% or less, to effectively disinfect lenses without causing irritation or harm to the eyes. The safety profile of PHMB in contact lens solutions is a key factor in its widespread use in this sector.

When used in wound care, the concentration of PHMB is carefully selected by healthcare professionals. While it is effective at low concentrations, the specific wound type, the presence of biofilms, and patient sensitivity are all considered. The aim is to provide a therapeutic environment that promotes healing while combating infection.

NINGBO INNO PHARMCHEM CO.,LTD. provides detailed technical data sheets and expert consultation to help clients determine the most appropriate PHMB disinfectant dosage for their unique applications. Correct dosage ensures not only the efficacy of PHMB but also its safe and responsible use, maximizing its benefits across all its diverse applications.
