Benzethonium chloride is a synthetic quaternary ammonium salt. This compound is an odorless white solid; soluble in water. It has surfactant, antiseptic, and anti-infective properties, and it is used as a topical antimicrobial agent in first aid antiseptics. It is also found in cosmetics and toiletries such as mouthwashes, anti-itch ointments, and antibacterial moist towelettes. Benzethonium chloride is also used in the food industry as a hard surface disinfectant. Benzethonium chloride exhibits a broad spectrum of microbiocidal activity against bacteria, fungi, mold and viruses. Independent testing shows that benzethonium chloride is highly effective against such pathogens as methicillin-resistant Staphylococcus aureus, Salmonella, Escherichia coli, Clostridium difficile, hepatitis B virus, hepatitis C virus, herpes simplex virus (HSV), human immunodeficiency virus (HIV), respiratory syncytial virus (RSV), and norovirus.
