A biocidal product (or biocide) can be a pesticide or an antimicrobial containing or generating an active substance(s) that is used to prevent or control various types of harmful or unwanted organisms.
Such products include disinfectants, preservatives, insect repellents, rodenticides and insecticides. Biocides control the intended target organism by a chemical or biological action. Biocides can be used by professionals and members of the public in a wide spectrum of use areas that are classified into product-types. To make sure the use of biocidal products do not have unacceptable risks for people, non-target animals and the environment, they are regulated to control their marketing, sale and use in order to minimise any risk.
