Biocides
Comprehensive testing to assess efficacy of biocides
What Are Biocides?
Biocides are chemical products used to control harmful organisms, for example bacteria, fungi and viruses. Biocides can be disinfectants, preservatives, antimicrobial wipes, antimicrobial surfaces, handwashes and handrubs.
Testing Biocides
Biocidal products on the market must comply with strict regulations. Within the European Union, the placement of biocides on the market is regulated by the Biocidal Products Regulation (BPR) overseen by the European Chemicals Agency (ECHA). In the UK, the Health & Safety Executive (HSE) regulates biocides under GB BPR and other areas will each have their own regulations. These guidelines aim to ensure the activity of biocides on the market while also protecting users and the environment.
Types of tests
Biocidal testing is often broken down into suspension tests, where liquids are challenged with the target organism, and carrier tests, where the selected organism is dried onto a surface which is then treated with the product. Standard test methods will specify which organisms should be tested, contact times and testing temperatures. All of these are designed to mimic the environment in which the product will be used. They may also specify the use of an interfering substance, such as protein or blood, which presents an increased challenge.
