    Biological Efficacy Testing in Biocidal Products – Microbial Safety and Effectiveness

    Biocidal products are chemical agents used to control or eliminate microorganisms. By reducing infection risks, they play a critical role in safeguarding both public health and environmental hygiene. Accurate testing of the biological efficacy of biocidal products—such as disinfectants and antiseptics—is essential to ensure safety and effectiveness.


    Antiseptics vs. Disinfectants

    • Antiseptics: Used on living tissues to kill or inhibit the growth of microorganisms. For example, hand antiseptics used for human hygiene.
    • Disinfectants: Used on inanimate surfaces and objects to destroy microorganisms, especially in hospitals, food processing areas, homes, and industrial settings.

    Laboratory testing confirms the ability of these products to kill or inhibit target microorganisms effectively.


    Why Are Biological Efficacy Tests Important?

    The effectiveness of chemical disinfectants and antiseptics depends on the correct formulation and usage conditions. Biological efficacy tests help verify:

    • Effect on Target Microorganisms (bacteria, fungi, spores, mycobacteria, viruses)
    • Minimum Effective Concentration suitable for intended use
    • Compliance with International Standards

    Tests Conducted at Our Laboratory

    At TTS Laboratory Services, we offer the following tests to evaluate the biological efficacy of biocidal products:

    1. Bactericidal Activity

      • Assesses the product’s ability to kill gram-positive and gram-negative bacteria.
    2. Mycobactericidal and Tuberculocidal Activity

      • Evaluates the product’s effect on mycobacteria, including Mycobacterium tuberculosis.
    3. Legionella Bactericidal Activity

      • Measures efficacy against waterborne bacteria like Legionella (especially important for water systems).
    4. Pool and Spa Disinfectant Efficacy Evaluation

      • Tests disinfectants used in swimming pools and spas for their bacterial kill rate.
    5. Fungicidal Activity

      • Determines the product’s effectiveness against fungi and molds.
    6. Sporicidal Activity

      • Evaluates the product’s ability to eliminate spore-form microorganisms.

    Biological Efficacy Tests for Medical Devices

    • Bactericidal, Fungicidal, and Yeasticidal Activity: Tests the disinfectants used for sterilizing medical instruments.
    • Mycobactericidal and Tuberculocidal Activity: Assesses efficacy against mycobacteria in healthcare settings.

    Non-Porous Surface Testing with Mechanical Action

    • Specifically evaluates disinfectant wipes for bacterial and yeast kill rates on surfaces.
