Explain cationic detergents.
Cationic detergents:- Cationic detergents are quaternary ammonium salts of amines with chlorides, acetates or bromides. They have cations at the soluble ends of the chain. Anions are chlorides, acetates or bromides, and cations are long chain hydrocarbons with a positive charge on the nitrogen atom. They are used as germicides and are expensive, for example, cetyltrimethyl ammonium chloride is used in hair conditioners. Hence, these cationic detergents are alkyl ammonium salts.
