Biocidal activity analysis is a critical testing process that measures the effect of active ingredients in biocidal products (e.g. disinfectants, antiseptics, preservatives) on harmful microorganisms such as bacteria, fungi, and viruses. These analyses are performed according to international standards (TS EN 1276, TS EN 1656, TS EN 13727, etc.) to determine the microbiological activity of the product. During the testing process, the extent to which the product kills or destroys microorganisms is evaluated; this helps determine whether the final product reduces health risks during use.
In addition, biocidal activity analysis is of great importance in terms of licensing and safety assessments of biocidal products. Compliance with the standards determined by the Ministry of Health and international accreditation institutions is necessary for the product to be accepted in the market. Thanks to these analyses, the product's duration of activity, stability properties, and long-term use safety are revealed; thus, reliable, high-quality products are provided to consumers and industry stakeholders.
Biocidal activity analysis is the testing and evaluation process used to measure the lethal or inhibitory effects of biocidal products (e.g. disinfectants, preservatives and antiseptics) on specific microorganisms. This analysis determines whether the active ingredients in the product are in the correct concentrations, how effective they are on microorganisms and the overall effectiveness of the product.
Biocidal activity analysis is a multi-stage testing process applied to measure the effect of biocidal products on certain pathogens (e.g. bacteria, fungi, viruses). Thanks to this analysis, it is revealed in detail whether the active substances contained in the product are in the correct concentrations, how effective they are on microorganisms, and whether they are safe during use. The process is carried out in a controlled laboratory environment in accordance with international standards.
The stages of biocidal activity analysis are as follows;
Preliminary Preparation and Sample Determination
In the first step, the composition of the biocidal product to be tested, the purpose of use, and the target microorganism groups are determined. Samples taken from the product are homogenized before the test and appropriate dilution processes are applied.
Creating the Test Environment and Conditions
In the laboratory environment, the necessary environment is prepared to evaluate the product's effectiveness in a realistic environment by providing test conditions (such as temperature, humidity, pH value) in accordance with international standards. The necessary cultures and reference strains for the tests are also provided at this stage.
Interaction Time and Application
Prepared samples are subjected to certain contact times with the determined microorganism cultures. This step is critical for the product to be exposed to pathogens for the defined period and to observe whether it is effective.
Measurement and Evaluation of Results
After the interaction, the number of microorganisms in the samples is determined and the log reduction value provided by the product is calculated. This data quantitatively reveals the effectiveness of the product and is compared to international standards.
Reporting and Compliance with Standards
In the final stage, all the data obtained, the methodology used, the applied test conditions and the results are presented in a detailed report. This report creates documents that will ensure the product's compliance with legal regulations and its reliable use in the market.
Biocidal activity analysis is a comprehensive testing process performed to measure how effective biocidal products are on specified microorganisms.
The main elements tested in biocidal activity analysis are as follows:
Bactericidal Activity Test
The lethal effect of the product on gram-positive and gram-negative bacteria is measured. This test evaluates the effectiveness of the product by determining how much the bacterial count is reduced at the end of certain contact times and by ensuring that the log reduction value reaches the target standards.
Fungicidal (Mushroom and Mold) Activity Test
The degree to which the product is lethal or growth inhibitory on fungal microorganisms such as fungi and mold is evaluated. As a result of the test, the capacity to destroy fungal spores and active fungal cells is determined.
Virucidal Activity Test
The product is tested on certain virus strains and the rate of inactivation of viruses is measured. This test is extremely important especially for biocidal products used in health applications or medical fields.
Sporicidal Activity Test
In cases where bacterial spores need to be destroyed due to their difficult structure; the effect of the product on microorganisms in spore form is analyzed. This test shows how effectively disinfectants can eliminate spores.
Mycobactericidal and Tuberculocidal Tests
The effect of the product on more resistant microorganisms, especially mycobacteria and tuberculosis-causing strains, is evaluated. These tests determine whether biocidal products used in the healthcare field meet critical safety and efficacy requirements.
The duration of biocidal activity analysis varies depending on the scope of the tests, the characteristics of the product, and the methodology used. Typically, efficacy tests involve certain contact times and incubation steps, so results can be completed within 24 to 48 hours; however, in cases of more comprehensive stability or long-term effect analyses, the process can take several days to weeks. In all cases, analyses are meticulously planned in accordance with international standards, and after implementation, detailed reports are prepared to document the reliability and effectiveness of the product.
Biocidal activity analysis is a comprehensive testing process used to identify and verify areas where biocidal products work effectively. This test method evaluates whether the product is suitable for its intended use by revealing the effect of the active ingredients in the product on specific microorganisms. This analysis can be applied to a wide range of biocidal product groups to measure the effectiveness of disinfectants, antiseptics, preservatives and many more.
Application areas for biocidal activity analysis are as follows;
Surface and Hand Disinfectants
The lethal or inhibitory effect of disinfectants and hand hygiene products used in areas such as hospitals, laboratories and restaurants on target pathogens such as bacteria, fungi, viruses and spores is tested, ensuring safety and effectiveness of use.
Antiseptic Products
Antiseptic solutions developed for surgical operations, wound cleaning and general medical applications are evaluated by the effect of the active ingredients they contain on microorganisms. In this way, it is confirmed that infection risks are reduced.
Textile and Surface Protective Products
Biocidal agents used in industrial or medical textiles and paints are tested to prevent the growth of harmful microbes on product surfaces. These analyses help provide long-term protection and meet hygiene standards.
Biocidal Products Used in Water Treatment and Cooling Systems
The extent to which biocidal products used in industrial water treatment systems, cooling towers or pool disinfection systems inactivate pathogens in water is determined. In this way, effective applications that protect environmental and human health are guaranteed.
Home Cleaning and Industrial Products
Home cleaning products, surface cleaners and disinfectants used in office and industrial environments are also subject to biocidal activity analysis. The extent to which these products are effective against microorganisms encountered in daily use is determined.
When performing biocidal activity analysis, many details must be meticulously considered in order to accurately and reliably evaluate the effectiveness of the product. In the laboratory environment where both microbiological and chemical tests will be performed; many elements play a critical role, from working conditions to sampling techniques, from the calibration of the devices used to the compliance of test protocols with international standards. The basic points to consider during this analysis are explained below:
In addition to scientifically documenting the effectiveness and safety of biocidal products, biocidal activity analyses offer many advantages for manufacturers, regulatory bodies and end users. The main advantages of these analyses are listed below and explained in items:
