Biocidal chemical analysis is an analysis method that allows detailed examination of the chemical substances contained in biocidal products in terms of quality and quantity. Biocidal products are chemical substances used to destroy or neutralize harmful organisms such as bactericides, fungicides, and virucides. In order for these products to be safe and effective, the active substances they contain must comply with national and international standards. This compliance is determined by biocidal chemical analysis.
A biocidal active substance can be; A chemical compound with a well-defined structure, A mixing process with two or more chemical compounds, A UVCB substance (unknown or variable component, complex reaction products or biological substances), Microorganisms such as bacteria, fungi, viruses, Plant extracts, oils and microorganisms, Products from the fermentation of microorganisms.
Main Parameters Examined in Biocidal Chemical Analyses are as follows:
Active ingredient amount and purity Formulation homogeneity Chemical stability pH and density values Physical properties (color, odor, viscosity, etc.) By-products and impurities
It is important to know the methods used in these analyses as well as parameters examined in biocidal chemical analyses.
Gas Chromatography (GC)
Gas Chromatography (GC) is used in the analysis of volatile biocides and products containing organic solvents. When combined with mass spectrometry (GC-MS), it is possible to detect even very low amounts of residues.
High Performance Liquid Chromatography (HPLC)
It is one of the most commonly used methods for the determination of active ingredients in biocides. This method is especially preferred for the separation and precise measurement of different components in mixed formulations. Both quantitative and qualitative analyses can be performed.
Spectrophotometric Methods
It is used especially in active ingredient analysis in simple biocide formulations. It is a fast and practical analysis method based on color change. UV-Vis spectrophotometers are widely preferred in this method.
They are active substances and preparations that contain one or more active substances, are offered for sale in a ready-to-use form, and have a controlling effect on any harmful organism in terms of chemical or biological aspects or restrict its movement, rendering it harmless. A biocidal product may consist of one or more active substances or may be prepared from one or more active substances. The form that reaches the user may be in the form of an aqueous active substance solution.
All biocidal active substances available on the EU market before 14 May 2000 and those notified and identified according to the Commission Regulation are published as existing biocidal active substances. Biocidal active substances not available on the EU market before 14 May 2000 or not notified or identified are new biocidal active substances that must be approved by each Member State in accordance with Directive 98/8/EC before they can be placed on the EU market.
Effectiveness Tests: Determines whether products are effective on target microorganisms or pests. It is performed according to standards such as EN 1276, EN 13697, EN 14476.
Chemical Analyses: The amount and stability of active substances (e.g. chlorine, alcohol, hydrogen peroxide) are analyzed. Product content, toxicity and deterioration risks are evaluated.
Physical and Stability Tests: The physical properties of the product (pH, viscosity, solubility) and its durability under storage conditions are tested.
Toxicological and Ecotoxicological Assessment: Potential risks to human health and the environment are evaluated.
Microbiological Tests: The presence of undesirable microorganisms in the product is checked.
Within the scope of the regulation, biocidal products must be performed in national/international laboratories accredited in an analysis parameter within the scope of ISO/IEC 17025 'General Requirements for the Competence of Test Calibration Laboratories'.
Purity analysis in biocides is the chemical examinations carried out to determine the purity rate of the active substance in biocidal products and the possible impurities in them. The quality and safety of a biocide is directly dependent on the purity level of the active substance it contains. Therefore, it is mandatory for biocides to be meticulously purified and checked with purity analyses before being put on the market.
Disinfectant chemical analysis is the process of examining the active ingredients and auxiliary components in disinfectant products in detail in terms of content, ratio and quality. These analyses are performed to verify the effectiveness of the product, to assess whether it is safe for health and to document its legal compliance.
Disinfectants are chemical products that are widely used in health institutions, the food industry, public areas and homes, and are intended to destroy or stop the growth of microorganisms. The correct formulation of these products is essential for effective and safe use.
