EC 1.11.1.6 en 9001-05-2 en For formulators and R&D teams in the ophthalmic industry, catalase is a crucial biocatalyst employed in two-step hydrogen peroxide disinfection systems for contact lenses. The enzyme's primary function is the rapid and controlled neutralization of the 3% hydrogen peroxide (H2O2) solution, which, while an effective broad-spectrum antimicrobial agent, is cytotoxic and a significant corneal irritant. Catalase is typically integrated into the system using two common delivery mechanisms: 1) Immobilized enzyme: Coated onto a solid-state catalytic disc (often platinum-based) fixed within the lens case. 2) Solid-Dose Formulation: Delivered as a tablet that dissolves to release the enzyme. The enzyme efficiently catalyzes the decomposition of hydrogen peroxide (2H2O2 --> 2H2O+ O2), rapidly reducing residual H2O2 concentrations to physiologically safe, non-irritating levels (e.g., <100 ppm). This bioconversion transforms the sterilizing solution into a sterile, isotonic, and biocompatible saline buffer, ensuring the lens is safe for ocular insertion after the defined disinfection and neutralization cycle. en Biological activity: 150 IU of Catalase are sufficient to completely remove 3% hydrogen peroxide in 10 minutes.Source: Microbial from Corynebacterium glutamicum en Catalase functions as a specific biocatalyst to neutralize hydrogen peroxide by decomposing it into water and oxygen, supporting applications in industrial processing, diagnostics, and research. en Appearance: Brownish-green, clear solution pH value: 7.0-8.0 Density (according to DAB 10): No limit Activity (+25°C, H2O2): ≥500,000 U/mL Glycerol (enzymatically): 310-430 mg/mL (≙ 25-35%, v/v) Ethanol (enzymatically): 71-87 mg/mL (≙ 9-11%, v/v) Water (calculated): No limit Purity (HPLC, TSK 3000, A280): ≥90 area% Bioburden: Total amount: ≤15 CFU/mL Germ differentiation according to Ph.
