Next to their positive role, microorganisms are associated with numerous undesirable effects, including many diseases, food spoilage, and decay. Humanity have been combating microorganisms for centuries. It was observed that water could be carried on long journeys in silver containers or with silver or copper coins, and food was preserved using salt and/or spices. In the modern era, the use of phenol as a disinfectant is well-known. The term "biocides" refers to a group of chemical compounds whose primary purpose is the deactivation or destruction of vegetative microorganisms. Due to their biocidal potential, they are used for disinfection, antiseptic, sterilization, and preservative treatments. Quaternary ammonium compounds belong to the group of cationic surfactants. Their general structure includes a cationic part consisting of a nitrogen atom bonded to four alkyl chains (the functional part of the molecule) and a halogen atom (usually chlorine).
