Menicon Meni Care Pure 250ml Contact lens solution

Natural polymer
ε-PL is a natural homopolymer of the essential amino acid L-lysine.
It is naturally secreted by various Streptomycetaceae bacteria and some filamentous fungi. Industrial production of ε-PL is carried out by aerobic fermentation of Streptomyces albulus strain.

Toxicity
Since ε-Polylysine is natural homopolymer of the essential amino acid L-lysine, the toxicity is lower than other cationic disinfectants used in commercial available multi-purpose solutions.

Antimicrobial activity
Because of the cationic nature of ε-PL, it shows high and wide antimicrobial activity. The predominant mechanism for ε-PL`s antimicrobial activity is its electrostatic adsorption onto the cell surface of microorganisms, leading to a stripping of the outer membrane and abnormal distribution of cytoplasm.

Stability
No degradation/denaturatior was observed after boiling at 100°C for 30 min or autoclaving at 120°C for 20 min, or after storage at room temperature for three years.
