  • Applications

    Lysozyme Hydrochloride (CAS 9066-59-5) is an antimicrobial enzyme used across industries to control bacterial growth in formulations. In food processing and dairy production, it acts as a natural preservative and antimicrobial agent, including cheese manufacture and beverage stabilization (wine and beer) to limit spoilage bacteria. In cosmetics and personal care, it may be added to improve microbial hygiene and product stability. In household and industrial cleaning, formulations may include Lysozyme Hydrochloride to inhibit microbial contamination on surfaces. In laboratory and biotech contexts, it is used as an enzymatic tool for bacterial cell-wall lysis and in research/reagent kits, with the salt form aiding solubility in aqueous systems. Use is subject to local regulations and formulation limits.
