Biocidal Product Analysis: Microbiological and Chemical Tests
What is a Biocidal Product?
What is a Biocidal Product?
Biocidal products are chemically and microbiologically effective products used to protect public health and ensure environmental hygiene. However, these products must be subjected to various analyzes in order to be used effectively and safely. Microbiological and chemical tests are the tests used to evaluate biocidal products in terms of efficacy, safety and compliance with regulatory standards.
Microbiological Testing: Essential Steps for Efficacy and Reliability
Microbiological tests are performed to assess the efficacy of biocidal products on target microorganisms. These tests are mandatory to verify the efficacy of the product before it is placed on the market.
Commonly Used Microbiological Test Methods
- Minimum Inhibition Concentration (MIC) TestDetermines the minimum concentration required for the product to kill or inhibit the growth of target microorganisms.
- Agar Diffusion TestProvides information about efficacy by measuring the zone of inhibition created by the product on the microorganism.
- Sporicidal and Fungicidal TestsEvaluate product efficacy on particularly challenging organisms such as fungi and spores.
Points to Consider
- Test protocols must comply with the European Union biocidal regulations (BPR).
- Studies must be performed according to ISO standards (e.g. ISO 22196).
- Sterile working conditions must be maintained to avoid the risk of contamination.
Chemical Analyses Content and Stability Check
Chemical analyses are performed to examine the accuracy, quantity and stability of the formulation components of biocidal products. Accurate chemical analysis ensures that the product is both effective and safe.
Featured Chemical Analysis Techniques
- Gas Chromatography (GC) and Mass Spectrometry (GC-MS)Used to determine the amount and type of organic components in the product.
- High Performance Liquid Chromatography (HPLC)Measures the purity and concentration of active ingredients in the product.
- pH and Viscosity MeasurementsControl the physicochemical properties of the product.
Important Considerations in Chemical Tests
- Sampling procedures must be carried out correctly and deterioration must be prevented during transportation and storage of samples.
- Regular calibration and maintenance of the instruments used is essential.
- It is important that test results are comprehensively reported in line with legal requirements.
Importance of Quality in Biocidal Product Analysis
Microbiological and chemical analyses are essential for the effective and safe use of biocidal products. Incorrect or inadequate testing can both increase health risks and jeopardize the product's place in the market.
The following criteria should be considered when selecting laboratories that test biocidal products:
- Being an accredited laboratory (for example, having ISO 17025 certification).
- Implementation of test protocols that are up-to-date and in line with international standards.
- Reliable and accurate reporting of results.
