In addition, quarternary ammonium compounds (which include our SDAs) are used as agents that are bioactive. They consist of a large range of antimicrobial activity over a broad range of pH and are used as pesticides, wood preservatives, sanitizers/disinfectants, fungicides, and hard-surface cleaners in commercial, medical, domestic, and agricultural applications. At very low temperatures, they are also considered effective against fungi, bacteria, and viruses. (Source: F&S Report)
