  • Applications

    Lysozyme (CAS 12650-88-3) is a natural antimicrobial enzyme with multiple industrial applications: in food processing as a preservative or antimicrobial agent to help control bacteria and extend shelf life (notably in dairy products and cheese); in cosmetics and personal care as a preservative or active antimicrobial additive to limit microbial growth in creams and cleansers; in cleaning products and household formulations as an enzyme-enhanced antimicrobial component for surface sanitation; in pharmaceutical and biotechnology workflows as a reagent for bacterial cell lysis in analytical and preparative processes such as DNA/RNA isolation and protein purification; and in coatings or inks as an antimicrobial additive in surface coatings. It is also explored for postharvest disease control in agriculture. Use is subject to local regulations and formulation limits.
