Cationic detergent - Types of Detergent
These types of detergent are mainly acetates or chlorides of quaternary amines. Being much more restricted than the anionic detergents they find out limited use. Such types of detergents though have germicidal properties and are employed quite broadly as germicides. Cetyltrimethyl-ammonium chloride, is an instance:
